Purpose
The purpose of this Virtual Connect Cookbook is to provide users of Virtual Connect with a better understanding of the concepts and steps required when integrating HP BladeSystem and Virtual Connect Flex-10 or FlexFabric components into an existing network.
The scenarios in this Cookbook vary from simplistic to more complex while covering a range of typical building blocks to use when designing Virtual Connect Flex-10 or FlexFabric solutions. Although these scenarios are shown individually, some scenarios could be combined to create a more complex and versatile Virtual Connect environment, such as the combined use of Shares Uplink Sets (SUS) and vNet Tunnels. Or Active/Active networks for North/South traffic flows, such as iSCSI or VDI, while also having the primary network traffic configured in a separate Shared Uplink Set with Active/Standby uplinks.
Existing users of Virtual Connect will quickly realize that as of VC firmware release 3.30 that the selection between “Mapped” and “Tunneled” modes are no longer of concern. The capabilities provided in those modes are now available in the default installation of VC firmware 3.30 and beyond. These capabilities and changes will be discussed in further detail later in this paper.
In addition to the features added in release 3.30, 4.01 is a major release containing several new features, including QoS and Min/Max downlink speed settings among others. This Cookbook will highlight and discuss some of these added features.
The scenarios as written are meant to be self-contained configurations and do not build on earlier scenarios, with this you may find some repetition or duplication of configuration across scenarios.
This paper is not meant to be a complete or detailed guide to Virtual Connect Flex-10 or FlexFabric, but is intended to provide the reader with some valid examples of how Virtual Connect Flex-10 or FlexFabric could be deployed within their environments. Many additional configurations or scenarios could also be implemented. Please refer to the following section for additional reference material on Virtual Connect, Flex-10 and FlexFabric.

Purpose 4
Introduction to Virtual Connect Flex-10 and FlexFabric
Virtual Connect is an industry standards-based implementation of server-edge virtualization. It puts an abstraction layer between the servers and the external networks so the LAN and SAN see a pool of servers rather than individual servers. Once the LAN and SAN connections are physically made to the pool of servers, the server administrator uses Virtual Connect management tools (Virtual Connect Manager (VCM) or Virtual Connect Enterprise Manager (VCEM)) to create a profile for each server.
Virtual Connect FlexFabric is an extension to Virtual Connect Flex-10 which leverages Fibre Channel over Ethernet (FCoE) protocols. By leveraging FCoE for connectivity to existing Fibre Channel SAN networks, we can reduce the number of switch modules and HBAs required within the server blade and enclosure. This in turn further reduces cost, complexity, power and administrative overhead.
This paper will discuss the differences between Flex-10 and FlexFabric and provide information and suggestions to assist the reader in determining the best option for their implementation of BladeSystem and Virtual Connect. For additional information on Virtual Connect, Flex-10 and/or FlexFabric, please review the documents below.

Connecting to Brocade Fibre Channel Fabric at 8Gb
NOTE: When VC 8Gb 20-port FC or VC FlexFabric 10Gb/24-port module Fibre Channel uplink ports
are configured to operate at 8Gb speed and connecting to HP B-series (Brocade) Fibre Channel SAN switches, the minimum supported version of the Brocade Fabric OS (FOS) is v6.3.1 and v6.4.x. In
addition, a fill word on those switch ports must be configured with option “Mode 3” to prevent
connectivity issues at 8Gb speed.
On HP B-series (Brocade) FC switches use the command;
portCfgFillWord (portCfgFillWord <Port#> <Mode>) to configure this setting:
Although this setting only affects devices logged in at 8G, changing the mode is disruptive regardless of the speed the port is operating at. The setting is retained and applied any time an 8G device logs in. Upgrades to FOS v6.3.1 or v6.4 from prior releases supporting only modes 0 and 1 will not change the existing setting, but a switch or port reset to factory defaults with FOS v6.3.1 or v6.4 will be configured to Mode 0 by default. The default setting on new units may vary by vendor. Please use portcfgshow CLI to view the current portcfgfillword status for that port.
Modes 2 and 3 are compliant with FC-FS-3 specifications (standards specify the IDLE/ARBF behavior of Mode 2 which is used by Mode 3 if ARBF/ARBF fails after 3 attempts). For most environments, Brocade recommends using Mode 3, as it provides more flexibility and compatibility with a wide range of devices. In the event that the default setting or Mode 3 does not work with a particular device, contact your switch vendor for further assistance. When connecting to Brocade SAN Switches at 8Gb, “portCfgFillWord” must be set to Mode 3 – If ARBF/ARBF fails use IDLE/ARBF. In order to use Mode 3, FOS v6.3.1 or v6.4.x or better is required.
Tunneled VLAN and Mapped VLANS
Readers that are familiar with earlier releases of Virtual Connect firmware features will realize that Virtual Connect 3.30 firmware removed the need to configure Virtual Connect in Mapped vs. Tunneled mode. As of Virtual Connect 3.30 firmware release, Virtual Connect now provides the ability to simultaneously take advantage of the features and capabilities that were provided in
either mapped or tunneled modes, there is no need to choose the domain’s mode of operation. The
key feature gained here is the ability to now use Mapped VLANs (multiple networks) and Tunneled networks within the same profile.
Virtual Connect VLAN Support – Shared Uplink Set
Shared Uplink Sets provide administrators with the ability to distribute VLANs into discrete and defined Ethernet Networks (vNet.) These vNets can then be mapped logically to a Server Profile Network Connection allowing only the required VLANs to be associated with the specific server NIC port. This also allows the flexibility to have various network connections for different physical Operating System instances (i.e. VMware ESX host and physical Windows host.)
Introduction to Virtual Connect Flex-10 and FlexFabric 13
Legacy VLAN Capacity
Legacy VLAN capacity mode allows up to 320 VLANs per Ethernet module, 128 VLANs per Shared Uplink Set and, up to 28 VLANs are allowed per FlexNIC port. Care must be taken not to exceed the limit per physical server port.
The following Shared Uplink Set rules apply to legacy capacity mode:
320 VLANs per Virtual Connect Ethernet Module 128 VLANs per Shared Uplink Set (single uplink port) 28 unique server mapped VLANs per server profile network connection
The above configuration rules apply only to a Shared Uplink set. If support for a larger numbers of VLANs is required, a VLAN Tunnel can be configured to support a large number of VLANs. Please see the Virtual Connect Release Notes for future details.
Expanded VLAN Capacity – Added in Virtual Connect 3.30 Release
This mode allows up to 1000 VLANs per domain when implementing a Share Uplink Set (SUS). The number of VLANs per shared uplink set is restricted to 1000. In addition, up to 162 VLANs are allowed per physical server port, with no restriction on how those VLANs are distributed among the server connections mapped to the same physical server port. Care must be taken not to exceed the limit per physical server port. For example, if you configure 150 VLAN mappings for a server connection (FlexNIC:a) of a FlexFabric physical server port, then you can only map 12 VLANs to the remaining three server connections (FlexNIC:b, FlexNIC:c, and FlexNIC:d) of the same physical server port. If you exceed the 162 VLAN limit, the physical server port is disabled and the four server connections are marked as Failed. Also, keep in mind that the FCoE SAN or iSCSI connection is also counted as a network mapping. In the event that greater numbers of VLANs are needed a vNet Tunnel can be used simultaneously with VLAN mapping.
The following Shared Uplink Set rules apply:
1000 VLANs per Virtual Connect Ethernet domain, 162 VLANs per Ethernet server port The above configuration rules apply only to a Shared Uplink set. If support for a greater
numbers of VLANs is required, a VLAN Tunnel can be configured to support a large number of VLANs. Please see the Virtual Connect Release Notes for further details.
When creating the Virtual Connect Domain, the default configuration in 3.30 is Legacy VLAN Capacity Mode (in Virtual Connect 4.01, the default mode is now Expanded VLAN Capacity), however, Multiple Networks and Tunnel mode can be used simultaneously. After Expanded VLAN Capacity mode is configured, in order to revert back to Legacy VLAN capacity mode, you must delete and recreate the Virtual Connect Domain.
Note: Expanded VLAN Capacity mode is not supported on the following 1Gb based Virtual Connect
Ethernet modules, such as:
HP 1/10Gb VC Ethernet Module HP 1/10Gb-F VC Ethernet Module
If these modules are inserted into an enclosure that is in Expanded VLAN Capacity mode, they are marked as incompatible. If these modules are installed in an enclosure, converting to Expanded VLAN Capacity mode will not be permitted.

Figure 9 - Configuring Expanded VLAN Capacity support
Bulk VLAN Creation
In addition to providing support for a greater number of VLANs, Virtual Connect now provides the ability to create several VLANs, within a Shared Uplink Set (SUS), in a single operation. Using the Bulk VLAN creation feature in the GUI or the add network-range command in the CLI many VLANs can be added to a SUS. In addition, copying an existing SUS is also now possible. When creating an Active/Active SUS configuration, you can create the first SUS, and then copy it.
Figure 10 - Example of adding multiple VLANs to a SUS through the GUI
Here is an example of creating a shared Uplink Set using the CLI command “add network-range” to create the more than 400 VLANs shown above.

Note: Earlier release of Virtual Connect firmware supported only 320 VLANs, in addition, to create each VLAN with SmartLink enabled required two lines of script. In the example above, over 300 VLANs are created in a single statement.
Copying a Shared Uplink Sets
Virtual Connect provides the ability to copy a Shared Uplink Set. This can be very handy when defining an Active/Active Shared Uplink Set design. You simply create the first SUS, and then copy it.
For example, after creating Shared Uplink Set VLAN-Trunk-1 you can copy it to VLAN-Trunk-2. You will then need to add uplinks to the new SUS and ensure all networks have SmartLink enabled. This can be accomplished as follows;
copy uplinkset VLAN-Trunk-1 VLAN-Trunk-2 fromVlanStr=1 toVlanStr=2 replace=last add uplinkport enc0:2:X5 Uplinkset=VLAN-Trunk-2 speed=auto add uplinkport enc0:2:X6 Uplinkset=VLAN-Trunk-2 speed=auto set network-range -quiet UplinkSet=VLAN-Trunk-1 VLANIds=101-105,2100-2400 SmartLink=enabled
vNets, Tunnels and Shared Uplink Sets
There are two types of vNets. The first is a simple vNet that will pass only untagged frames. The second is a vNet tunnel which will pass tagged frames for one or many VLANs.
vNet
The vNet is a simple network connection between one or many server NICs to one or many uplink ports.
A vNet could be used to connect a single VLAN, without tagging, to one or many server NICs. If this network is configured as a VLAN, by configuring the upstream switch port as an access or untagged port, by extension, any server connected to this vNet would reside in that VLAN, but would not need to be configured to interpret the VLAN tags.
Benefits of a vNet
A vNet can be utilized in one of two ways, a simple vNet, used to pass untagged frames and a tunneled vNet. A tunneled vNet can be used to pass many VLANs without modifying the VLAN tags, functioning as a transparent VLAN Pass-Thru module.
vNet Tunnel
A tunneled vNet will pass VLAN tagged frames, without the need to interpret or forward those frames based on the VLAN tag. Within a tunneled vNet the VLAN tag is completely ignored by Virtual Connect and the frame is forwarded to the appropriate connection (server NIC[s] or uplinks) depending on frame direction flow. In this case, the end server would need to be configured to interpret the VLAN tags. This could be a server with a local operating system, in which the network stack would need to be configured to understand which VLAN the server was in, or a virtualization host with a vSwitch supporting multiple VLANs.
The tunneled vNet can support up to 4096 VLANs.
Benefits of a vNet Tunnel
A vNet Tunnel can present one or many VLANs to a server NIC. When additional VLANs are added to the upstream switch port, they are made available to server with no changes required within Virtual Connect. All presented VLANs are pass through the tunnel, unchanged.
Introduction to Virtual Connect Flex-10 and FlexFabric 16
Shared Uplink Set (SUS)
The SUS provides the ability to support VLAN tagging and forward frames based on the VLAN tags of those frames. The SUS connects one or many server NICs to one or many uplink ports. A SUS would be configured for the specific VLANs it will support. If support for additional VLANs is required, those VLANs need to be configured within the SUS. When connecting a server NIC to a network within a SUS, there are two choices provided. The key difference between these two options is the state in which the frame is passed to the server NIC. When configuring a server NIC for network connection;
1. Selecting a single network – which would be mapped to a specific VLAN.
If a single network is selected, the frames will be presented to the server NIC WITHOUT a VLAN tag. In this case the host operating system does not need to understand which VLAN it resides in. When the server transmits frames back to Virtual Connect, those frames will not be tagged, however; Virtual Connect will add the VLAN tag and forward the frame onto the correct VLAN.
2. Selecting multiple networks – which would provide connectivity to several VLANs.
The Map VLAN Tags feature provides the ability to use a Shared Uplink Set to present multiple networks to a single NIC. If you select Multiple Networks when assigning a Network to a server NIC, you will have the ability to configure multiple Networks (VLANS) on that server NIC. At this point Virtual Connect tags ALL the packets presented to the NIC unless the Native check box is selected for one of the networks, in which case packets from this network (VLAN) will be untagged, and any untagged packets leaving the server will be placed on this Network (VLAN).
With Mapped VLAN Tags, you can create a Shared Uplink Set that contains ALL the VLANs you want to present to your servers, then present only ONE network (the one associated with the VLAN we want the server NIC in) to the Windows, LINUX or the ESX Console NIC, then select Multiple Networks for the NIC connected to the ESX vSwitch and select ALL the networks that we want presented to the ESX host vSwitch. The vSwitch will then break out the VLANs into port groups and present them to the guests. Using Mapped VLAN Tags minimizes the number of uplinks required.
Benefits of a SUS
A Shared Uplink Set can be configure to support both tagged and un-tagged network traffic to a server NIC, which simplifies the overall configuration and minimizes the number of uplink cables required to support the network connections.
MAC Cache Failover
When a Virtual Connect Ethernet uplink that was previously in standby mode becomes active, it can take several minutes for external Ethernet switches to recognize that the c-Class server blades can now be reached on this newly-active connection. Enabling Fast MAC Cache Failover causes Virtual Connect to transmit Ethernet packets on newly-active links, which enables the external Ethernet switches to identify the new connection more quickly (and update their MAC caches appropriately). This transmission sequence repeats a few times at the MAC refresh interval (5 seconds recommended) and completes in about 1 minute.
When implementing Virtual Connect in an Active/Standby configuration, where some of the links connected to a Virtual connect Network (whether a SUS or vNet) are in standby, MAC Cache Fail-over would be employed to notify the switch as a link transitions from Standby to Active within Virtual Connect.
Note: Be sure to set switches to allow MAC addresses to move from one port to another without waiting for an expiration period or causing a lock out.
Introduction to Virtual Connect Flex-10 and FlexFabric 17
Role Management
New to Virtual Connect 4.01 is the ability to provide a more granular control of each of the operational user roles provided. In prior releases, each role had a set level of access.
Figure 11 – Role Operations provides the ability to set the level of access a specific operational role is provided
Virtual Connect DirectAttach Virtual Connect SAN fabrics (FlatSAN with 3PAR)
Virtual Connect Direct Attached SAN fabrics, provides the ability to directly connect HP FlexFabric to an HP 3PAR storage array and completely eliminate the need for a traditional SAN fabric and the administrative overhead associated with maintaining the fabric. FlatSAN is supported on FlexFabric modules through Ports X1-X4, simply connect the FlexFabric modules to available ports on the 3PAR array and configure the Virtual Connect fabrics for “DirectAttach”.
Figure 12 - When configuring FlatSAN, chose the Fabric Type of “DirectAttach”
Note: See Scenario 6 in the Virtual Connect Fibre Channel Cookbook for a details on implementation
of FlatSAN. http://bizsupport1.austin.hp.com/bc/docs/support/SupportManual/c01702940/c01702940.pdf
Virtual Connect QoS
QoS is used to provide different priorities for designated networking traffic flows and guarantee a certain level of performance through resource reservation. QoS is important for reasons such as:
Providing Service Level Agreements for network traffic and to optimize network utilization Different traffic types such as management, back up, and voice having different
requirements for throughput, jitter, delays and packet loss
IP-TV, VOIP and expansion of internet is creating additional traffic and latency
requirements
Introduction to Virtual Connect Flex-10 and FlexFabric 18
In some cases, capacity cannot be increased. Even when possible, increasing capacity may
still encounter issues if traffic needs to be re-routed due to a failure
Traffic must be categorized and then classified. Once classified, traffic is given priorities and scheduled for transmission. For end to end QoS, all hops along the way must be configured with similar QoS policies of classification and traffic management. Virtual Connect manages and guarantees its own QoS settings as one of the hops within the networking infrastructure.
Network Access Groups (NAG)
Before Virtual connect 3.30, any server profile could be assigned any set of networks. If policy dictated that some networks should not be accessed by a system that accessed other networks (for example, the Intranet and the Extranet or DMZ networks) there was no way to enforce that policy automatically.
With Virtual Connect 3.30 and later, network access groups are defined by the network administrator and associated with a set of networks that can be shared by a single server. Each server profile is associated with one network access group. A network cannot be assigned to the server profile unless the profile is a member of the network access group associated with that network. A network access group can contain multiple networks. A network can reside in more than one network access group, such as a management or VMotion VLAN.
Up to 128 network access groups are supported in the domain. Ethernet networks and server profiles that are not assigned to a specific network access group are added to the domain Default network access group automatically. The Default network access group is predefined by VCM and cannot be removed or renamed.
If you are updating to Virtual Connect 3.30, all current networks are added to the Default network access group and all server profiles are set to use the Default network access group. Network communication within the network access group behaves similarly to earlier versions of Virtual Connect firmware, because all profiles can reach all networks.
If you create a new network access group, NetGroup1, and copy or move existing networks from the Default network access group to NetGroup1, then a profile that uses NetGroup1 cannot use networks included in the Default network access group. Similarly, if you create a new network and assign it to NetGroup1 but not to the Default network access group, then a profile that uses the Default network access group cannot use the new network. Therefore, an administrator cannot inadvertently, or intentionally, place a server on networks that reside in different Network Access Groups.
Virtual Connect LACP Timers
Virtual Connect provides two options for configuring uplink redundancy (Auto and Failover). When the connection mode is set to "Auto", Virtual Connect uses Link Aggregation Control Protocol to aggregate uplink ports from a Network or Shared Uplink Set into Link Aggregation Groups. As part of the LACP negotiation to form a LAG, the remote switch sends a request for the frequency of the control packets (LACPDU). This frequency can be "short" or "long." Short is every 1 second with a 3 second timeout. Long is every 30 seconds with a 90 second timeout.
Prior to Virtual Connect 4.01 this setting defaulted to short. Starting with Virtual Connect 4.01 this setting can be set to short or long. The domain-wide setting can be changed on the Ethernet Settings (Advanced Settings) screen. Additionally, each Network or Shared Uplink Set also has a LACP timer setting. There are three possible values: Domain-Default, Short, or Long. The domain default option sets the LACP timer to the domain-wide default value that is specified on the Advanced Ethernet Settings screen.
This setting specifies the domain-wide default LACP timer. VCM uses this value to set the duration of the LACP timeout and to request the rate at which LACP control packets are to be received on LACP-supported interfaces. Changes to the domain-wide setting are immediately applied to all existing networks and shared uplink sets.
Using the "long" setting can help prevent loss of LAGs while performing in-service upgrades on upstream switch firmware.
Introduction to Virtual Connect Flex-10 and FlexFabric 19
Multiple Networks Link Speed Settings (Min/Max Bandwidth Control)
A new feature to Virtual Connect 4.01 provides the ability to configure a minimum and maximum preferred NIC link speed for server downlinks. This setting can be configured as a global default for NICs configured with multiple networks, but can also be fine-tuned at the individual NIC level. The
default global Preferred Speed is set to 10Gb. The new “Maximum Link Connection Speed” setting can be configured to enable a NIC to transmit at a speed greater that it’s configured speed. The
default Maximum speed is set to 10Gb. If these settings are remain as default, each NIC, although configured for a set speed (minimum guaranteed speed), will be able to transmit at a rate as high as 10Gb. This feature is also known as “Min/Max”.
Configuring Multiple Networks Link Speed Settings (Min/Max)
Configure the global default setting for Preferred Link Speed to 2Gb and the Maximum Speed to 8Gb. This global setting applies to connections configured for Multiple Networks only.

Sample rate of 4 minutes, collecting up to 20 hours of samples. Sample rate of 5 minutes, collecting up to 25 hours of samples. Sample rate of 1 hour, collecting up to 12.5 days of samples.
Configuring Throughput Statistics
Telemetry support for network devices caters to seamless operations and interoperability by providing visibility into what is happening on the network at any given time. It offers extensive and useful detection capabilities which can be coupled with upstream systems for analysis and trending of observed activity.
The Throughput Statistics configuration determines how often the Throughput Statistics are collected and the supported time frame for sample collection before overwriting existing samples. When the time frame for sample collection is reached, the oldest sample is removed to allocate room for the new sample. Configuration changes can be made without having to enable Throughput Statistics. Applying configuration changes when Throughput statistics is enabled clears all existing samples.
Some conditions can clear existing Throughput Statistics:
Disabling the collection of Throughput Statistics clears all existing samples. Changing the sampling rate clears all existing samples. Power cycling a Virtual connect Ethernet module clears all Throughput Statistics samples
for that module.
Collected samples are available for analysis on the Throughput Statistics screen (on page 226 of the Virtual Connect 4.01 User Guide), accessible by selecting Throughput Statistics from the Tools pull-down menu.
The following table describes the available actions for changing Throughput Statistics settings.
Connecting VC Flex-10/10D or VC FlexFabric to the CORE
The baseline Virtual Connect technology adds a virtualization layer between the edge of the server and the edge of the existing LAN and SAN. As a result, the external networks connect to a shared resource pool of MAC addresses and WWNs rather than to MACs/WWNs of individual servers.
LAN-Safe
From the external networking view, Virtual Connect FlexFabric, Flex-10, or Ethernet uplinks appear to be multiple NICs on a large server. Virtual Connect ports at the enclosure edge look like server connections. This is analogous to a VMware environment that provides multiple MAC addresses to the network through a single NIC port on a server.
Virtual Connect works seamlessly with your external network:
Does not participate in Spanning Tree Protocol (STP) on the network uplinks to the data
Introduction to Virtual Connect Flex-10 and FlexFabric 21
center. This avoids potential STP configuration errors that can negatively affect switches in the network and the servers connected to those switches
Uses an internal loop prevention algorithm to automatically detect and prevent loops
inside a Virtual Connect domain. Virtual Connect ensures that there is only one active uplink for any single network at one time
Allows aggregation of uplinks to data center networks (using LACP and fail-over) Supports VLAN tagging on egress or pass-thru of VLAN tags in tunneled mode Supports Link Layer Discovery Protocol (LLDP) and Jumbo Frames
Virtual Connect was designed to connect to the network as an endpoint device, as such, it is capable of connecting to any network switch, at any layer, including directly to the core switch, providing the ability to flatten the network as required.
Choosing VC Flex-10/10D or VC FlexFabric
When choosing between Flex-10/10D and FlexFabric, the first question to ask is whether a direct connection to a Fibre Channel SAN fabric will be required, today or in the future. The key difference between Flex-10 and FlexFabric is that FlexFabric modules leverage the built in Converged Network Adapter (CNA) provided in the G7 and Gen 8 BladeSystem servers to provide FCoE (Fibre Channel) connectivity. FCoE connectivity is provided through the integrated Converged Network Adapter (CNA) and the FlexFabric modules, the FlexFabric modules connect directly to the existing Fibre Channel switch fabrics, no additional components would be required, such as a traditional HBA.
With the release of Virtual connect firmware 4.01, the Flex-10/10D and FlexFabric modules can also be utilized to provide dual hop FCoE connectivity to a switch that supports FCoE connections, in which case the FCoE traffic would traverse the Ethernet uplinks and connect to the SAN through the ToR or Core switch.
Virtual Connect 3.70 provided a new capability when connecting to HP’s 3PAR storage arrays using
Fibre Channel, allowing the 3PAR array to be directly connected to the FlexFabric modules. This
feature is call “FlatSAN” and provides the ability to completely eliminate the need for a fibre
channel SAN fabric, further reducing the cost of implementation and management of a blade server environment.
If direct connection to a Fibre Channel SAN fabric is not required, then all the capabilities of the CNA in the G7 and Gen 8 Blade and Virtual Connect can be obtained through the use of the Flex-10/10D modules, the only feature not available would be direct connection to a fibre channel SAN fabric. Fibre Channel connectivity could be later added through the use of traditional Virtual Connect Fibre Channel modules, and FC HBAs. iSCSI support is provided through either FlexFabric or Flex-10 modules.
If Fibre Channel is not used, then the second Physical Function (pf) on each port would be used for Ethernet. If Flex-10 modules are used with Virtual connect Fibre Channel modules, ensure an HBA is installed in the appropriate MEZZ slot in the blade and simply configure a “FC HBA” within the server profile and map it to the appropriate FC SAN Fabrics. In this case, FCoE SAN Fabrics and FCoE CNAs would not be utilized. An example of this configuration is provided in Scenario 9.
The Scenarios provided in this document could be implemented on either; Flex-10, Flex-10/10D (with VC-FC Modules for FC connections) or FlexFabric modules, with the exception of the dual hop FCoE, which would not be supported on Flex-10 modules.
FlexFabric also provides the ability to support “Direct Attached” SAN fabrics to an HP 3PAR SAN, which provides the ability to eliminate the SAN fabric.
Note: Dual hop FCoE connectivity is provided through Flex-10/10D and FlexFabric modules only. The original Flex-10 module does not support dual hop FCoE.

Note: All 1Gb Blade LAN adapters will function with any of the Virtual Connect 10Gb Ethernet modules, however, will operate at 1Gb.
Determining Network Traffic Patterns and Virtual Connect network design (Active/Standby vs. Active/Active)
When choosing which Virtual Connect network design to use (Active/Active (A/A) vs. Active/Standby (A/S) uplinks), consider the type of network traffic this enclosure will need to support. For example, will there be much server to server traffic needed within the enclosure, or is the traffic flow mainly in/out bound of the enclosure.
Network traffic patterns, North/South (N/S) vs. East/West (E/W), should be considered when designing a Virtual Connect solution as network connectivity can be implemented in a way to maximize the connected bandwidth and/or minimize the need for server to server traffic to leave the enclosure when communicating on the same VLAN with other servers within the same enclosure.
Introduction to Virtual Connect Flex-10 and FlexFabric 23
For example; if the solution being implemented will have a high level of in/out or North/South traffic flow, an A/A network design would likely be the better solution as it would enable all connected uplinks. However, if a greater level of network traffic is between systems within the same enclosure/VLAN, such as a multi-tiered application, then a better design may be A/S, as this would minimize or eliminate any server to server communications from leaving the enclosure.
Determining whether network connectivity is A/A vs. A/S is not a domain configuration issue or concern. Networks are independent of one another and both A/A and A/S networks could be implemented in the same Virtual Connect domains. As an example, an iSCSI connection could be configured as A/A to support a high rate of N/S traffic between targets and initiators. Whereas the LAN connectivity for the users and applications could be more E/W where an A/S network design could be implemented.
In an active/standby network design, all servers would have both NICs connected to the same Virtual Connect network. All communications between servers within the Virtual Connect Domain would occur through this network, no matter which network adapter is active. In the example below, if Windows Host 1 is active on NIC 1 and Windows Host 2 is active on NIC 2, the communications between servers will cross the internal stacking links. For external communications, all servers in the enclosure will use the Active uplink (currently) connected to Bay 1, no matter which NIC they are active on.
Figure 14 - This is an example of an Active/Standby network configuration. One uplink is active, while the other is in standby, and available in the event of a network or module failure
In an A/A network design, all servers would have their NICs connected to opposite Virtual Connect networks. Communications between servers within the Virtual Connect Domain would depend on which NIC each server was active on. In the following example, if Windows Host 1 is active on NIC 1 and Windows Host 2 is active on NIC 2, the communications between servers will NOT cross the internal stacking links and would need to leave the enclosure and re-enter via the opposite module; however, if a higher rate of external communications is require, vs. peer to peer, then an active/active configuration may be preferred as both uplinks would be actively forwarding traffic. Also, if both servers were active on the same NIC, then communications between servers would remain within the module/enclosure.
Introduction to Virtual Connect Flex-10 and FlexFabric 24
Figure 15 - This is an example of an Active/Active network configuration. Both uplinks are actively forwarding traffic.
Figure 16 - Both A/A (iSCSI_x) and A/S (vNet_PROD) networks are used in this example.
Note: Alternatively, if Fibre Channel will not be required, the iSCSI networks could be connected as
iSCSI hardware accelerated and would be connected to the FlexHBA.

Single Domain/Enclosure Scenarios
Overview
This Cookbook will provide several configuration scenarios of Virtual Connect Flex-10/10D and FlexFabric, using an HP BladeSystem c7000 enclosure. Virtual Connect also supports Multi­Enclosure stacking, for up to 4 enclosures, which provides a single point of management and can further reduce cable connectivity requirements. For Virtual connect stacked configurations, see the Virtual Connect Multi-Enclosure Stacking Reference Guide. Each scenario will provide an overview of the configuration, show how to complete that configuration and include both GUI and CLI (scripted) methods. Where possible, examples for Windows and/or VMware vSphere will also be provided.
Requirements
This Cookbook will utilize a single HP BladeSystem c7000 enclosure with TWO Virtual Connect FlexFabric or Flex-10/10D modules installed in I/O Bays 1 and 2 and a BL460c Gen 8 half height BladeSystem Servers in server Bay 1. Some of the scenarios will provide Ethernet only connections, in which case Flex-10/10D modules may be used. In the scenarios where Fibre Channel connectivity is required, FlexFabric modules will be used, with the exception of Scenario 9 which uses Flex­10/10D and Virtual Connect Fibre Channel modules.
The server’s integrated converged network adapters (CNA) will connect to Bays 1 and 2, with two 10Gb FlexFabric adapter ports. Each FlexFabric Adapter port supports Ethernet and iSCSI or Fibre Channel over Ethernet (FCoE) when connected to FlexFabric modules. Port 1 will connect to the FlexFabric module in Bay 1 and Port 2 will connect to the FlexFabric module in Bay 2.
The Flex-10/10D modules are connected to a pair of 10Gb Ethernet switches for standard LAN connectivity.
The FlexFabric modules and VC-FC modules are linked to a pair of 8Gb Brocade fibre channel switches for SAN connectivity.
In each scenario, it’s assumed that a Virtual Connect Domain has been created either through the GUI or a CLI script and no Virtual Connect Networks, uplink sets or Server Profiles have been created. Virtual Connect scripting examples are provided within each scenario as well as additional examples in Appendix C.

Single Domain/Enclosure Scenarios 29
Scenario 1 – Simple vNet with Active/Standby Uplinks – Ethernet and FCoE – Windows 2008 R2
Overview
This simple configuration uses the Virtual Connect vNet along with FCoE for SAN connectivity. When VLAN mapping is not required, the vNet is the simplest way to connect Virtual Connect to a network and server. In this scenario, the upstream network switch connects a network to a single port on each FlexFabric module. In addition, Fibre Channel uplinks will also be connected to the FlexFabric modules to connect to the existing Fibre Channel infrastructure.
No special upstream switch configuration is required as the switch is in the factory default configuration, typically configured as an Access or untagged port on either the default VLAN or a specific VLAN. In this scenario, Virtual Connect does not receive VLAN tags.
When configuring Virtual Connect, we can provide several ways to implement network fail-over or redundancy. One option would be to connect TWO uplinks to a single vNet; those two uplinks would connect from different Virtual Connect modules within the enclosure and could then connect to the same or two different upstream switches, depending on your redundancy needs. An alternative would be to configure TWO separate vNets, each with a single or multiple uplinks configured. Each option has its advantages and disadvantages. For example; an Active/Standby configuration places the redundancy at the VC level, where Active/Active places it at the OS NIC teaming or bonding level. We will review the first option in this scenario.
In addition, several vNets can be configured to support the required networks to the servers within the BladeSystem enclosure. These networks could be used to separate the various network traffic types, such as iSCSI, backup and VMotion from production network traffic.
This scenario will also leverage the Fibre Channel over Ethernet (FCoE) capabilities of the FlexFabric modules. Each Fibre channel fabric will have one uplink connected to each of the FlexFabric modules.
Requirements
This scenario will support both Ethernet and fibre channel connectivity. In order to implement this scenario, an HP BladeSystem c7000 enclosure with one or more server blades and TWO Virtual Connect FlexFabric modules, installed in I/O Bays 1& 2 are required. In addition, we will require ONE or TWO external Network switches. As Virtual Connect does not appear to the network as a switch and is transparent to the network, any standard managed switch will work with Virtual Connect. The Fibre Channel uplinks will connect to the existing FC SAN fabrics. The SAN switch ports will need to be configured to support NPIV logins. One uplink from each FlexFabric module will be connected the existing SAN fabrics.

Installation and configuration
Switch configuration
As the Virtual Connect module acts as an edge switch, Virtual Connect can connect to the network at either the distribution level or directly to the core switch.
The appendices provide a summary of the cli commands required to configure various switches for connection to Virtual Connect. The configuration information provided in the appendices for this scenario assumes the following information:
The switch ports are configured as ACCESS or untagged ports, either presenting the
Default VLAN or a specific VLAN and will be forwarding untagged frames
As an alternative, if the switch ports were configured as TRUNK ports and forwarding
multiple VLANS, Virtual Connect would forward those tagged frames to the host NICs configured for this network, however; the Virtual Connect network would need to be configured for VLAN Tunneling. The connected host would then need to be configured to interpret those VLAN tags.
The network switch port should be configured for Spanning Tree Edge as Virtual Connect appears to the switch as an access device and not another switch. By configuring the port as Spanning Tree Edge, it allows the switch to place the port into a forwarding state much quicker than otherwise, this allows a newly connected port to come online and begin forwarding much quicker.
The SAN switch ports connecting to the FlexFabric module must be configured to accept NPIV logins.
Configuring the VC module
Physically connect Port 1 of network switch 1 to Port X15 of the VC module in Bay 1 Physically connect Port 1 of network switch 2 to Port X5 of the VC module in Bay 2
Note: if you have only one network switch, connect VC port X5 (Bay 2) to an alternate port on the same switch. This will NOT create a network loop and Spanning Tree is not required.
Physically connect Port X1 on the FlexFabric in module Bay 1 to a switch port in SAN Fabric A Physically connect Port X1 on the FlexFabric in module Bay 2 to a switch port in SAN Fabric B
VC CLI commands
In addition to the GUI many of the configuration settings within VC can also be accomplished via a CLI command set. In order to connect to VC via a CLI, open an SSH connection to the IP address of the active VCM. Once logged in, VC provides a CLI with help menus. The Virtual Connect CLI guide also provides many useful examples. Throughout this scenario the CLI commands to configure VC for each setting are provided.
Configuring Expanded VLAN Capacity via GUI
Virtual Connect release 3.30 provided an expanded VLAN capacity mode when using Shared Uplink Sets, this mode can be enabled through the Ethernet Settings tab or the VC CLI. The default configuration for a new Domain install is “Expanded VLAN Capacity” mode, Legacy mode is no longer available and the Domain cannot be downgraded.
Scenario 1 – Simple vNet with Active/Standby Uplinks – Ethernet and FCoE – Windows 2008 R2 32
To verify the VLAN Capacity mode
On the Virtual Connect Manager screen, Left pane, click Ethernet Settings, Advanced
Settings
Select Expanded VLAN capacity Verify Expanded VLAN Capacity is configured and Legacy VLAN Capacity is greyed out.
Note: Legacy VLAN mode will only be presented if 1Gb Virtual Connect Modules are present, in which case the domain would be limited to Firmware version 3.6x.
Configuring Expanded VLAN Capacity via CLI
The following command can be copied and pasted into an SSH based CLI session with Virtual Connect;
# Set Expanded VLAN Capacity set enet-vlan -quiet VlanCapacity=Expanded
Figure 24 - Enabling Expanded VLAN Capacity
Note: If a 1Gb VC Ethernet module is present in the Domain, Expanded VLAN capacity will be greyed
out, this is only supported with 10Gb based VC modules. Also, once Expanded VLAN capacity is selected, moving back to Legacy VLAN capacity mode will require a domain deletion and rebuild.
Configuring Fast MAC Cache Failover
When an uplink on a VC Ethernet Module that was previously in standby mode becomes active, it can take several minutes for external Ethernet switches to recognize that the c-Class server blades must now be reached on this newly active connection.
Enabling Fast MAC Cache Failover forces Virtual Connect to transmit Ethernet packets on newly active links, which enables the external Ethernet switches to identify the new connection more quickly (and update their MAC caches appropriately). This transmission sequence repeats a few times at the MAC refresh interval (five seconds is the recommended interval) and completes in about one minute.
Configuring the VC Module for Fast Mac Cache Fail-over via GUI (Ethernet settings)
Set Fast MAC Cache Fail-over to 5 Seconds
On the Virtual Connect Manager screen, Left pane, click Ethernet Settings, Advanced

Defining a new vNet via GUI
Create a vNet and name it “vNet-PROD”
Login to Virtual Connect, if a Domain has not been created, create it now, but cancel out of
the configuration wizards after the domain has been created.
On the Virtual Connect Manager screen, click Define, Ethernet Network to create a vNet  Enter the Network Name of “vNet-PROD”
o Note; Do NOT select the options (ie; SmartLink, Private Networks or Enable VLAN
Tunnel)
Select Add Port, then add the following ports;
o Enclosure 1 (enc0), Bay 1, Port X5 o Enclosure 1 (enc0), Bay 2, Port X5
Leave Connection Mode as Auto Optionally, Select Advanced Network Settings and set the Preferred speed to 4Gb and the
Maximum speed to 6Gb.
Select Apply
Note: By connecting TWO Uplinks from this vNet we have provided a redundant path to the network. As each uplink originates from a different VC module, one uplink will be Active and the second will be in Standby. This configuration provides the ability to lose an uplink cable, network switch or depending on how the NICs are configured at the server (teamed or un-teamed), even a VC module. An Active/Standby configuration also provides better East/West connectivity.
Note: SmartLink – In this configuration SmartLink should NOT be enabled. SmartLink is used to turn off downlink ports within Virtual Connect, if ALL available uplinks to a vNet are down. We will use SmartLink in a later scenario.

Review
In this scenario we have created a simple vNet utilizing uplinks originating from each FlexFabric Module, by doing so we provide redundant connections out of the Virtual Connect domain, where one uplink will be active and the alternate uplink will be in standby. We create two FCoE SAN Fabrics, utilizing a single uplink each.
We created a server profile, with two NICs connected to the same vNet, which provides the ability to sustain a link or module failure and not lose connection to the network, this configuration also guarantees that ALL server to server communications within the enclosure will remain inside the enclosure. Alternatively, we could have created two vNets and assigned uplinks from one module to each vNet, providing an Active/Active uplink scenario.
Additionally, FCoE port 1 is connected to SAN fabric FCoE_A and FCoE SAN port 1 is connected to SAN Fabric FCoE_B, providing a multi-pathed connected to the SAN.
Additional uplinks could be added to either the San fabrics or the Ethernet networks, which could increase performance and/or availability.
Results – Windows 2008 R2 Networking Examples
We have successfully configured FlexFabric with a simple vNet and redundant SAN fabrics. We have created a server profile to connect to the vNet with TWO NICs and the SAN fabrics using the FCoE connections created within the profile.
Although both Ethernet and Fibre channel connectivity is provided by the CNA adapter used in the G7 and Gen 8 servers; each capability (LAN and SAN) is provided by a different component of the adapter, they appear in the server as individual network and SAN adapters.
Figure 32 - Example of Emulex's OneCommand Manager Utility (formerly known as HBA Anywhere). Note that there are 3 Ethernet personalities and one FCoE personality per port, as configured in the server profile.
The following graphics show a Windows 2008 R2 server with TWO FlexNICs configured at 6Gb. You will also notice that Windows believes there are 6 NICs within this server. However, only TWO NICs are currently configured within the FlexFabric profile, the extra NICs are offline and could be disabled. If we did not require SAN connectivity on this server, the FCoE connections could be deleted and the server would then have 8 NIC ports available to the OS.

Note: The NICs that are not configured within VC will appear with a red x as not connected. You can
go into Network Connections for the Windows 2008 server and disable any NICs that are not currently in use. Windows assigns the NICs as NIC 1-6, whereas three of the NICs will reside on LOM:1 and three on LOM:2. You may need to refer to the FlexFabric server profile for the NIC MAC addresses to verify which NIC is which.

The following graphics provides an example of a Windows 2008 R2 server with TWO NICs connected to the network, initially each NIC has its own TCP/IP address, alternatively, both NICs could be teamed to provide NIC fail-over redundancy. If an active uplink or network switch were to fail, Virtual Connect would fail-over to the standby uplink. In the event of a Virtual Connect FlexFabric module failure, the server’s NIC teaming software would see one of the NICs go offline, assuming it was the active NIC, NIC teaming would fail-over to the standby NIC.
Figure 37 - Both NICs for Profile App-1are connected to the network through vNet-PROD
NIC Teaming
If higher availability is desired, NIC teaming in Virtual Connect works the same way as in standard network configurations. Simply, open the NIC teaming Utility and configure the available NICs for teaming. In this example, we have only TWO NICs available, so selecting NICs for teaming will be quite simple. However, if multiple NICs are available, ensure that the correct pair of NICs is teamed. You will note the BAY#-Port# indication within each NIC. Another way to confirm you have the correct NIC is to verify through the MAC address of the NIC. You would typically TEAM a NIC from Bay 1 to Bay 2 for example.
The following graphics provide an example of a Windows 2008 R2 server with TWO NICs teamed and connected to the network. In the event of an Uplink or switch failure, VC will fail-over to the standby uplinks, if a VC FlexFabric module were to fail, the NIC teaming software would fail-over to the standby NIC.

Summary
We presented a Virtual Connect Network scenario by creating a simple vNet, we configured the new Min/Max Network speed setting for the vNet. A dual path SAN fabric for storage connectivity was also configured.
When VC profile App-1 is applied to the server in bay1 and the server is powered up, it has one NIC connected through each FlexFabric module connected to “vNet-PROD”, which connects to the network infrastructure through the 10Gb uplinks. These NICs could now be configured as individual NICs with their own IP address or as a pair of TEAMED NICs. Either NIC could be active. As a result, this server could access the network through either NIC or either uplink cable, depending on which is active at the time. Each NIC is configured for a guaranteed minimum bandwidth of 4Gb, with a maximum of 6Gb of network bandwidth and each FCoE port is configured for 4Gb of SAN bandwidth with the ability to burst to a maximum of 8Gb.
Additional NICs could be added within FlexFabric, by simply powering the server off and adding up to a total of 6 NICs, the NIC speed can then be adjusted accordingly to suit the needs of each NIC. If additional or less SAN bandwidth is required, the speed of the SAN connection can also be adjusted.
As additional servers are added to the enclosure, simply create additional profiles, or copy existing profiles, configure the NICs for LAN and SAN fabrics as required and apply them to the appropriate server bays and power the server on.

Scenario 2 –Shared Uplink Sets with Active/Active uplinks and 802.3ad (LACP) ­Ethernet and FCoE – Windows 2008 R2
Overview
This scenario will implement the Shared Uplink Set (SUS) to provide support for multiple VLANs. Virtual Connect 3.30 increased the number of VLANs supported on a Shared Uplink Set and provides some enhanced GUI and CLI features that reduce the effort required to create large number of VLANs. The upstream network switches connect to each FlexFabric module and two separate Shared Uplink Sets, providing an Active/Active configuration, LACP will be used to aggregate those links.
As multiple VLANs will be supported in this configuration, the upstream switch ports connecting to the FlexFabric modules will be configured to properly present those VLANs. In this scenario, the upstream switch ports will be configured for VLAN trunking/VLAN tagging.
When configuring Virtual Connect, we can provide several ways to implement network fail-over or redundancy. One option would be to connect TWO uplinks to a single Virtual Connect network; those two uplinks would connect from different Virtual Connect modules within the enclosure and could then connect to the same upstream switch or two different upstream switches, depending on your redundancy needs. An alternative would be to configure TWO separate Virtual Connect networks, each with a single, or multiple, uplinks configured. Each option has its advantages and disadvantages. For example; an Active/Standby configuration places the redundancy at the VC level, where Active/Active places it at the OS NIC teaming or bonding level. We will review the second option in this scenario.
In addition, several Virtual Connect Networks can be configured to support the required networks to the servers within the BladeSystem enclosure. These networks could be used to separate the various network traffic types, such as iSCSI, backup and VMotion from production network traffic.
This scenario will also leverage the Fibre Channel over Ethernet (FCoE) capabilities of the FlexFabric modules. Each fibre channel fabric will have two uplinks connected to each of the FlexFabric modules.
Requirements
This scenario will support both Ethernet and fibre channel connectivity. In order to implement this scenario, an HP BladeSystem c7000 enclosure with one or more server blades and TWO Virtual Connect FlexFabric modules, installed in I/O Bays 1& 2 are required. In addition, we will require ONE or TWO external Network switches. As Virtual Connect does not appear to the network as a switch and is transparent to the network, any standard managed switch will work with Virtual Connect. The Fibre Channel uplinks will connect to the existing FC SAN fabrics. The SAN switch ports will need to be configured to support NPIV logins. Two uplinks from each FlexFabric module will be connected to the existing SAN fabrics.
Scenario 2 –Shared Uplink Sets with Active/Active uplinks and 802.3ad (LACP) - Ethernet and FCoE – Windows 2008 R2 47
Figure 44 - Physical View; Shows two Ethernet uplinks from Ports X5 and X6 on Module 1 and 2 to Ports 1 and 2 on each network switch. The SAN fabrics are also connected redundantly, with TWO uplinks per fabric, from ports X1 and X2 on module 1 to Fabric A and ports X1 and X2 to Fabric B.
Figure 45 - Logical View; the server blade profile is configured with TWO FlexNICs and 2 FlexHBAs. NICs 1 and 2 are connected to VLAN-101-x which are part of the Shared Uplink Sets, VLAN-Trunk-1 and VLAN-Trunk-2 respectively. The VLAN-Trunks are connected, at 10Gb, to a network switch, through Ports X5 and X6 on each FlexFabric Module in Bays 1 and 2. The FCoE SAN connections are connected through ports X1 and X2 on each FlexFabric module. In addition, SAN Fabric FCoE_A connects to the existing SAN Fabric A through port X1 on Module 1 (Bay 1) and FCoE_B connects to the existing SAN Fabric B through port X1 on Module 2 (Bay 2)

Installation and configuration
Switch configuration
As the Virtual Connect module acts as an edge switch, Virtual Connect can connect to the network at either the distribution level or directly to the core switch.
The appendices provide a summary of the cli commands required to configure various switches for connection to Virtual Connection. The configuration information provided in the appendices for this scenario assumes the following information:
The switch ports are configured as VLAN TRUNK ports (tagging) to support several VLANs.
All frames will be forwarded to Virtual Connect with VLAN tags. Optionally, one VLAN could be configured as (Default) untagged, if so, then a corresponding vNet within the Shared Uplink Set would be configured and set as “Default”
Note: when adding additional uplinks to the SUS, if the additional uplinks are connecting from the same FlexFabric module to the same switch, in order to ensure all the uplinks are active, the switch ports will need to be configured for LACP within the same Link Aggregation Group.
The network switch port should be configured for Spanning Tree Edge as Virtual Connect appears to the switch as an access device and not another switch. By configuring the port as Spanning Tree Edge, it allows the switch to place the port into a forwarding state much quicker than otherwise, this allows a newly connected port to come online and begin forwarding much quicker.
The SAN switch ports connecting to the FlexFabric module must be configured to accept NPIV logins.
Configuring the VC module
Physically connect Port 1 of network switch 1 to Port X5 of the VC module in Bay 1 Physically connect Port 2 of network switch 1 to Port X6 of the VC module in Bay 1 Physically connect Port 1 of network switch 2 to Port X5 of the VC module in Bay 2 Physically connect Port 2 of network switch 2 to Port X6 of the VC module in Bay 2
Note: if you have only one network switch, connect VC ports X5 and X6 (Bay 2) to an alternate ports on the same switch. This will NOT create a network loop and Spanning Tree is not required.
Physically connect Ports X1/X2 on the FlexFabric in module Bay 1 to switch ports in SAN Fabric A
Physically connect Ports X1/X2 on the FlexFabric in module Bay 2 to switch ports in SAN Fabric B

Scenario 2 –Shared Uplink Sets with Active/Active uplinks and 802.3ad (LACP) - Ethernet and FCoE – Windows 2008 R2 54
Note: In this scenario we have created two independent Share Uplink Sets (SUS), each originating from the opposite FlexFabric Modules, by doing so we provide the ability to create separate and redundant connections out of the Virtual Connect domain. When we create the server profiles, you will see how the NICs will connect to VLANs accessed through the opposite VC module, which provides the ability to create an Active / Active uplink scenario. Alternatively, we could have created a single SUS and assigned both sets of these uplink ports to the same SUS, however, this would have provided an Active/Standby uplink scenario, as shown in Scenario 5.
Note: As we did not configure the Min/Max network speed setting for any of these networks, you will notice in each profile that ALL configured NICs will have a configured speed of 10Gb. If you wish to limit the speed of specific networks, you could edit each network and configure a maximum speed.

Review
In this scenario we have created Two Shared Uplink Sets (SUS), providing support for many VLANs. Uplinks originating from each FlexFabric Module connect to each SUS, by doing so we provide redundant connections out of the Virtual Connect domain. As multiple uplinks are used for each SUS, we have also leveraged LACP to improve uplink performance. In this scenario, all uplinks will be active. We also created two FCoE SAN Fabrics.
We created a server profile, with two NICs connected to the same external VLAN (101) through VC networks VLAN-101-1 and VLAN-101-2, which provides the ability to sustain a link or module failure and not lose connection to the network. VLAN101-1 and VLAN101-2 are configured to support VLAN 101, frames will be presented to the NIC(s) without VLAN tags (untagged), these two NICs are connected to the same VLAN, but taking a different path out of the enclosure.
Additionally, FCoE port 1 is connected to SAN fabric FCoE_A and FCoE SAN port 2 is connected to SAN Fabric FCoE_B, providing a multi-pathed connected to the SAN.
Additional uplinks could be added to either the San fabrics or the Ethernet networks, which could increase performance and/or availability.
Scenario 2 –Shared Uplink Sets with Active/Active uplinks and 802.3ad (LACP) - Ethernet and FCoE – Windows 2008 R2 58
Results – Windows 2008 R2 Networking Examples
We have successfully configured FlexFabric with a shared uplink set and redundant SAN fabrics. We have created a server profile to connect the TWO NICs to VLAN 101 and the SAN fabrics using the FCoE connections created within the profile.
Although both Ethernet and Fibre channel connectivity is provided by the CNA used in the G7 and Gen 8 servers; each capability (LAN and SAN) is provided by a different component of the adapter, they appear in the server as individual network and SAN adapters.
Figure 55 - Example of Emulex's OneCommand Manager Utility (formerly known as HBA Anywhere). Note that there are 3 Ethernet personalities and one FCoE personality per port, as configured in the server profile.
The following graphics show a Windows 2008 R2 server with TWO FlexNICs configured at 6Gb. You will also notice that Windows believes there are 6 NICs within this server. However, only TWO NICs are currently configured within the FlexFabric profile, the extra NICs are offline and could be disabled. If we did not require SAN connectivity on this server, the FCoE connections could be deleted and the server would then have 8 NIC ports available to the OS.
Note: the BL465c G7 and BL685c G7 utilize an NC551i chipset (BE2), whereas the BL460c G7, BL620c G7 and BL680c G7 utilize an NC553i chipset (BE3) and the Gen 8 blades typically have a NC554 adapter which also utilizes the BE3 chipset. Both the BE2 and BE3 chipsets share common drivers and firmware.

Note: The NICs that are not configured within VC will appear with a red x as not connected. You can
go into Network Connections for the Windows 2008 server and Disable any NICs that are not currently in use. Windows assigns the NICs as NIC 1-6, whereas three of the NICs will reside on LOM:1 and three on LOM:2. You may need to refer to the FlexFabric server profile for the NIC MAC addresses to verify which NIC is which.

Note: In Windows 2008 and later the actual NIC speed is displayed as configured in server Profile. Also, note that the speed displayed is the maximum speed setting, not the minimum setting.
Figure 59 - Windows 2008 R2, Device Manager, SIX NICs are shown, however, we have only configured two of the NICs and two FCoE HBAs.
The following graphics provides an example of a Windows 2008 R2 server with TWO NICs connected to the network, initially each NIC has its own TCP/IP address, alternatively, both NICs could be teamed to provide NIC fail-over redundancy. If an active uplink or network switch were to fail, Virtual Connect would fail-over to the standby uplink. In the event of a Virtual Connect FlexFabric
module failure, the server’s NIC teaming software would see one of the NICs go offline, assuming it
was the active NIC, NIC teaming would fail-over to the standby NIC.
Figure 60 – Each NIC is connected to VLAN 101
Scenario 2 –Shared Uplink Sets with Active/Active uplinks and 802.3ad (LACP) - Ethernet and FCoE – Windows 2008 R2 61
NIC Teaming
If higher availability is desired, NIC teaming in Virtual Connect works the same way as in standard network configurations. Simply, open the NIC teaming Utility and configure the available NICs for teaming. In this example, we have only TWO NICs available, so selecting NICs for teaming will be quite simple. However, if multiple NICs are available, ensure that the correct pair of NICs is teamed. You will note the BAY#-Port# indication within each NIC. Another way to confirm you have the correct NIC is to verify through the MAC address of the NIC. You would typically TEAM a NIC from Bay 1 to Bay 2 for example.
The following graphics provide an example of a Windows 2008 R2 server with TWO NICs teamed and connected to the network. In the event of an Uplink or switch failure, VC will fail-over to the standby uplinks, if a VC FlexFabric module were to fail, the NIC teaming software would fail-over to the standby NIC.
Figure 61 – Team both NICs, using the HP Network Configuration Utility
Figure 62 - Both NICs for Profile App-1are teamed and connected to the network through vNet-PROD
Various modes can be configured for NIC Teaming, such as NFT, TLB etc. Once the Team is created, you can select the team and edit its properties. Typically, the default settings can be used.

Summary
We presented a Virtual Connect Network scenario by creating two shared uplink sets (SUS), each SUS is connected with TWO active uplinks, both SUS’ can actively pass traffic. We included a dual path SAN fabric for storage connectivity.
When VC profile App-1 is applied to the server in bay1 and the server is powered up, it has one NIC connected through FlexFabric module 1 (connected to VLAN-101-1), the second NIC is connected through FlexFabric module 2 (connected to VLAN-101-2). Each NIC is configured at 6Gb. These NICs could now be configured as individual NICs with their own IP address or as a pair of TEAMED NICs. Either NIC could be active. As a result, this server could access the network through either NIC or either uplink, depending on which NIC is active at the time. Each NIC is configured for a guaranteed minimum bandwidth of 4Gb, with a maximum of 10Gb of network bandwidth and each FCoE port is configured for 4Gb of SAN bandwidth with the ability to burst to a maximum of 8Gb.
Additional NICs could be added within FlexFabric, by simply powering the server off and adding up to a total of 6 NICs, the NIC speed can then be adjusted accordingly to suit the needs of each NIC. If additional or less SAN bandwidth is required, the speed of the SAN connection can also be adjusted.
As additional servers are added to the enclosure, simply create additional profiles, or copy existing profiles, configure the NICs for LAN and SAN fabrics as required and apply them to the appropriate server bays and power the server on.
Scenario 2 –Shared Uplink Sets with Active/Active uplinks and 802.3ad (LACP) - Ethernet and FCoE – Windows 2008 R2 64
Scenario 3 – Shared Uplink Set with Active/Active Uplinks and 802.3ad (LACP) ­Ethernet and FCoE Boot from SAN – Windows 2008 R2
Overview
This scenario will implement the Shared Uplink Set (SUS) to provide support for multiple VLANs. The upstream network switches connect a shared uplink set to two ports on each FlexFabric modules, LACP will be used to aggregate those links. This scenario is identical to Scenario 2, however, scenario 3 also provides the steps to configure a Windows 2008 R2 server to Boot from SAN using the FCoE connections provided by FlexFabric. When using Virtual Connect/FlexFabric in a Boot from SAN implementation, no custom or special HBA configuration is required. The HBA configuration is controlled by Virtual Connect and maintained as part of the server profile. Once the server profile has been configured and applied to the server bays, the controller will be configured on the next and subsequent boot. When we later configure the server profile, we will also configure the HBA boot parameters.
As multiple VLANs will be supported in this configuration, the upstream switch ports connecting to the FlexFabric modules will be configured to properly present those VLANs. In this scenario, the upstream switch ports will be configured for VLAN trunking/VLAN tagging.
When configuring Virtual Connect, we can provide several ways to implement network fail-over or redundancy. One option would be to connect TWO uplinks to a single Virtual Connect network; those two uplinks would connect from different Virtual Connect modules within the enclosure and could then connect to the same upstream switch or two different upstream switches, depending on your redundancy needs. An alternative would be to configure TWO separate Virtual Connect networks, each with a single, or multiple, uplinks configured. Each option has its advantages and disadvantages. For example; an Active/Standby configuration places the redundancy at the VC level, where Active/Active places it at the OS NIC teaming or bonding level. We will review the second option in this scenario.
In addition, several Virtual Connect Networks can be configured to support the required networks to the servers within the BladeSystem enclosure. These networks could be used to separate the various network traffic types, such as iSCSI, backup and VMotion from production network traffic.
This scenario will also leverage the Fibre Channel over Ethernet (FCoE) capabilities of the FlexFabric modules. Each fibre channel fabric will have two uplinks connected to each of the FlexFabric modules.
Requirements
This scenario will support both Ethernet and fibre channel connectivity. In order to implement this scenario, an HP BladeSystem c7000 enclosure with one or more server blades and TWO Virtual Connect FlexFabric modules, installed in I/O Bays 1& 2 are required. In addition, we will require ONE or TWO external Network switches. As Virtual Connect does not appear to the network as a switch and is transparent to the network, any standard managed switch will work with Virtual Connect. The fibre channel uplinks will connect to the existing FC SAN fabrics. The SAN switch ports will need to be configured to support NPIV logins. Two uplinks from each FlexFabric module will be connected to the existing SAN fabrics.
Scenario 3 – Shared Uplink Set with Active/Active Uplinks and 802.3ad (LACP) - Ethernet and FCoE Boot from SAN – Windows 2008 R2 65
Figure 67 - Physical View; Shows two Ethernet uplinks from Ports X5 and X6 on Module 1 and 2 to Ports 1 and 2 on each network switch. The SAN fabrics are also connected redundantly, with TWO uplinks per fabric, from ports X1 and X2 on module 1 to Fabric A and ports X1 and X2 to Fabric B.
Figure 68 - Logical View; the server blade profile is configured with TWO FlexNICs and 2 FlexHBAs. NICs 1 and 2 are connected to VLAN-101-x which are part of the Shared Uplink Sets, VLAN-Trunk-1 and VLAN-Trunk-2 respectively. The VLAN-Trunks are connected, at 10Gb, to a network switch, through Ports X5 and X6 on each FlexFabric Module in Bays 1 and 2. The FCoE SAN connections are connected through ports X1 and X2 on each FlexFabric module. In addition, SAN Fabric FCoE_A connects to the existing SAN Fabric A through port X1 on Module 1 (Bay 1) and FCoE_B connects to the existing SAN Fabric B through port X1 on Module 2 (Bay 2).
Scenario 3 – Shared Uplink Set with Active/Active Uplinks and 802.3ad (LACP) - Ethernet and FCoE Boot from SAN – Windows 2008 R2 66
Installation and configuration
Switch configuration
As the Virtual Connect module acts as an edge switch, Virtual Connect can connect to the network at either the distribution level or directly to the core switch.
The appendices provide a summary of the cli commands required to configure various switches for connection to Virtual Connect. The configuration information provided in the appendices for this scenario assumes the following information:
The switch ports are configured as VLAN TRUNK ports (tagging) to support several VLANs.
All frames will be forwarded to Virtual Connect with VLAN tags. Optionally, one VLAN could be configured as (Default) untagged, if so, then a corresponding vNet within the Shared Uplink Set would be configured and set as “Default”
Note: when adding additional uplinks to the SUS, if the additional uplinks are connecting from the same FlexFabric module to the same switch, in order to ensure all the uplinks are active, the switch ports will need to be configured for LACP within the same Link Aggregation Group.
The network switch port should be configured for Spanning Tree Edge as Virtual Connect appears to the switch as an access device and not another switch. By configuring the port as Spanning Tree Edge, it allows the switch to place the port into a forwarding state much quicker than otherwise, this allows a newly connected port to come online and begin forwarding much quicker.
The SAN switch ports connecting to the FlexFabric module must be configured to accept NPIV logins.
Configuring the VC module
Physically connect Port 1 of network switch 1 to Port X5 of the VC module in Bay 1 Physically connect Port 2 of network switch 1 to Port X6 of the VC module in Bay 1 Physically connect Port 1 of network switch 2 to Port X5 of the VC module in Bay 2 Physically connect Port 2 of network switch 2 to Port X6 of the VC module in Bay 2
Note: if you have only one network switch, connect VC ports X5 and X6 (Bay 2) to an alternate port on the same switch. This will NOT create a network loop and Spanning Tree is not required.
Physically connect Ports X1/X2 on the FlexFabric in module Bay 1 to switch ports in SAN Fabric A
Physically connect Ports X1/X2 on the FlexFabric in module Bay 2 to switch ports in SAN Fabric B
VC CLI commands
Many of the configuration settings within VC can also be accomplished via a CLI command set. In order to connect to VC via a CLI, open an SSH connection to the IP address of the active VCM. Once logged in, VC provides a CLI with help menus. Through this scenario the CLI commands to configure VC for each setting will also be provided.
Configuring Expanded VLAN Capacity via GUI
Virtual Connect release 3.30 provided an expanded VLAN capacity mode when using Shared Uplink Sets, this mode can be enabled through the Ethernet Settings tab or the VC CLI. The default configuration for a new Domain install is “Expanded VLAN Capacity” mode, Legacy mode is no longer available and the Domain cannot be downgraded.
Scenario 3 – Shared Uplink Set with Active/Active Uplinks and 802.3ad (LACP) - Ethernet and FCoE Boot from SAN – Windows 2008 R2 67
To verify the VLAN Capacity mode
On the Virtual Connect Manager screen, Left pane, click Ethernet Settings, Advanced
Settings
Select Expanded VLAN capacity Verify Expanded VLAN Capacity is configured and Legacy VLAN Capacity is greyed out.
Note: Legacy VLAN mode will only be presented if 1Gb Virtual Connect Modules are present, in which case the domain would be limited to Firmware version 3.6x.
Configuring Expanded VLAN Capacity via CLI
The following command can be copied and pasted into an SSH based CLI session with Virtual Connect;
# Set Expanded VLAN Capacity set enet-vlan -quiet VlanCapacity=Expanded
Figure 69 - Enabling Expanded VLAN Capacity
Note: if a 1Gb VC Ethernet module is present in the Domain, Expanded VLAN capacity will be greyed
out, this is only supported with 10Gb based VC modules. Also, once Expanded VLAN capacity is selected, moving back to Legacy VLAN capacity mode will require a domain deletion and rebuild.
Defining a new Shared Uplink Set (VLAN-Trunk-1)

Scenario 3 – Shared Uplink Set with Active/Active Uplinks and 802.3ad (LACP) - Ethernet and FCoE Boot from SAN – Windows 2008 R2 72
Note: In this scenario we have created two independent Share Uplink Sets (SUS), each originating from the opposite FlexFabric Modules, by doing so we provide the ability to create separate and redundant connections out of the Virtual Connect domain. When we create the server profiles, you will see how the NICs will connect to VLANs accessed through the opposite VC module, which provides the ability to create an Active / Active uplink scenario. Alternatively, we could have created a single SUS and assigned both sets of these uplink ports to the same SUS, however, this would have provided an Active/Standby uplink scenario, as shown in Scenario 5.

Scenario 3 – Shared Uplink Set with Active/Active Uplinks and 802.3ad (LACP) - Ethernet and FCoE Boot from SAN – Windows 2008 R2 76
Review
In this scenario we have created Two Shared Uplink Sets (SUS), providing support for many VLANs. Uplinks originating from each FlexFabric Module connect to each SUS, by doing so we provide redundant connections out of the Virtual Connect domain. As multiple uplinks are used for each SUS, we have also leveraged LACP to improve uplink performance. In this scenario, all uplinks will be active. We also created two FCoE SAN Fabrics.
We created a server profile, with two NICs connected to the same external VLAN (101) through VC networks VLAN-101-1 and VLAN-101-2, which provides the ability to sustain a link or module failure and not lose connection to the network. VLAN101-1 and VLAN101-2 are configured to support VLAN 101, frames will be presented to the NIC(s) without VLAN tags (untagged), these two NICs are connected to the same VLAN, but taking a different path out of the enclosure.
Additionally, FCoE port 1 is connected to SAN fabric FCoE_A and FCoE SAN port 2 is connected to SAN Fabric FCoE_B, providing a multi-pathed connected to the SAN. The server profile was also configured for Boot to SAN over the FCoE connections. With Virtual Connect, there is no need to configure the SAN HBA directly when booting to SAN, all required configuration is maintained in the server profile. During installation of windows 2008 R2, ensure that Microsoft the MPIO role is enabled.
The FCoE SAN fabric connects to each SAN fabric over two uplinks per module.
Results – Windows 2008 R2 Networking Examples
We have successfully configured FlexFabric with a shared uplink set and redundant SAN fabrics. We have created a server profile to connect the TWO NICs to VLAN 101 and the SAN fabrics using the FCoE connections created within the profile. We also configured the profile to Boot Windows 2008 R2 from a SAN LUN.
Although both Ethernet and Fibre channel connectivity is provided by the CNA used in the G7 and Gen 8 servers; each capability (LAN and SAN) is provided by a different component of the adapter, they appear in the server as individual network and SAN adapters.
Figure 79 - Example of Emulex's OneCommand Manager Utility (formerly known as HBA Anywhere). Note that there are 3 Ethernet personalities and one FCoE personality per port, as configured in the server profile.
The following graphics show a Windows 2008 R2 server with TWO FlexNICs configured at 6Gb. You will also notice that Windows believes there are 6 NICs within this server. However, only TWO NICs
Scenario 3 – Shared Uplink Set with Active/Active Uplinks and 802.3ad (LACP) - Ethernet and FCoE Boot from SAN – Windows 2008 R2 77
are currently configured within the FlexFabric profile, the extra NICs are offline and could be disabled. If we did not require SAN connectivity on this server, the FCoE connections could be deleted and the server would then have 8 NIC ports available to the OS.
Note: the BL465c G7 and BL685c G7 utilize an NC551i chipset (BE2), whereas the BL460c G7, BL620c G7 and BL680c G7 utilize an NC553i chipset (BE3) and the Gen 8 blades typically have a NC554 adapter which also utilizes the BE3 chipset. Both the BE2 and BE3 chipsets share common drivers and firmware.

Note: The NICs that are not configured within VC will appear with a red x as not connected. You can
go into Network Connections for the Windows 2008 server and Disable any NICs that are not currently in use. Windows assigns the NICs as NIC 1-6, whereas three of the NICs will reside on LOM:1 and three on LOM:2. You may need to refer to the FlexFabric server profile for the NIC MAC addresses to verify which NIC is which.

Scenario 3 – Shared Uplink Set with Active/Active Uplinks and 802.3ad (LACP) - Ethernet and FCoE Boot from SAN – Windows 2008 R2 79
The following graphics provides an example of a Windows 2008 R2 server with TWO NICs connected to the network, initially each NIC has its own TCP/IP address, alternatively, both NICs could be teamed to provide NIC fail-over redundancy. If an active uplink or network switch were to fail, Virtual Connect would fail-over to the standby uplink. In the event of a Virtual Connect FlexFabric
module failure, the server’s NIC teaming software would see one of the NICs go offline, assuming it
was the active NIC, NIC teaming would fail-over to the standby NIC.
Figure 84 - Each NIC is connected to VLAN 101
NIC Teaming
If higher availability is desired, NIC teaming in Virtual Connect works the same way as in standard network configurations. Simply, open the NIC teaming Utility and configure the available NICs for teaming. In this example, we have only TWO NICs available, so selecting NICs for teaming will be quite simple. However, if multiple NICs are available, ensure that the correct pair of NICs is teamed. You will note the BAY#-Port# indication within each NIC. Another way to confirm you have the correct NIC is to verify through the MAC address of the NIC. You would typically TEAM a NIC from Bay 1 to Bay 2 for example.
The following graphics provide an example of a Windows 2008 R2 server with TWO NICs teamed and connected to the network. In the event of an Uplink or switch failure, the SUS will lose connection to the network; SmartLink will alert the NIC teaming software to this event, by turning the server NIC port off, causing the NIC teaming software to fail-over to the alternate NIC.

Summary
We presented a Virtual Connect Network scenario by creating two shared uplink sets (SUS), each
SUS is connected with TWO active uplinks, both SUS’ can actively pass traffic. We included a dual
path FCoE SAN fabric for storage connectivity and boot to SAN.
When VC profile App-1 is applied to the server in bay1 and the server is powered up, it has one NIC connected through FlexFabric module 1 (connected to VLAN-101-1), the second NIC is connected through FlexFabric module 2 (connected to VLAN-101-2). Each NIC is configured at 6Gb. These NICs could now be configured as individual NICs with their own IP address or as a pair of TEAMED NICs. Either NIC could be active. As a result, this server could access the network through either NIC or either uplink, depending on which NIC is active at the time. Each NIC is configured for a guaranteed minimum bandwidth of 8Gb, with a maximum of 10Gb of network bandwidth and each FCoE port is configured for 4Gb of SAN bandwidth with the ability to burst to a maximum of 8Gb.
We also configured the server profile to Boot to SAN, this configuration is part of the profile, if the profile is moved to a different server bay, the Boot to SAN information will follow with the profile. The profile can also be copied and assigned additional server bays, each new profile will retain the Boot to SAN configuration, however, will also acquire new WWN addresses.
Additional NICs could be added within FlexFabric, by simply powering the server off and adding up to a total of 6 NICs, the NIC speed can then be adjusted accordingly to suit the needs of each NIC. If additional or less SAN bandwidth is required, the speed of the SAN connection can also be adjusted.
As additional servers are added to the enclosure, simply create additional profiles, or copy existing profiles, configure the NICs for LAN and SAN fabrics as required and apply them to the appropriate server bays and power the server on.

Scenario 4 – Shared Uplink Set with Active/Active Uplinks and 802.3ad (LACP) – Ethernet, FCoE SAN - Windows 2008 R2 Hyper-V
Overview
This scenario will implement the Shared Uplink Set (SUS) to provide support for multiple VLANs. The upstream network switches connect a shared uplink set to two ports on each FlexFabric modules, LACP will be used to aggregate those links.
As multiple VLANs will be supported in this configuration, the upstream switch ports connecting to the FlexFabric modules will be configured to properly present those VLANs. In this scenario, the upstream switch ports will be configured for VLAN trunking/VLAN tagging.
When configuring Virtual Connect, we can provide several ways to implement network fail-over or redundancy. One option would be to connect TWO uplinks to a single Virtual Connect network; those two uplinks would connect from different Virtual Connect modules within the enclosure and could then connect to the same upstream switch or two different upstream switches, depending on your redundancy needs. An alternative would be to configure TWO separate Virtual Connect networks, each with a single, or multiple, uplinks configured. Each option has its advantages and disadvantages. For example; an Active/Standby configuration places the redundancy at the VC level, where Active/Active places it at the OS NIC teaming or bonding level. We will review the second option in this scenario.
In addition, several Virtual Connect Networks can be configured to support the required networks to the servers within the BladeSystem enclosure. These networks could be used to separate the various network traffic types, such as iSCSI, backup and VMotion from production network traffic.
This scenario will also leverage the Fibre Channel over Ethernet (FCoE) capabilities of the FlexFabric modules. Each fibre channel fabric will have two uplinks connected to each of the FlexFabric modules.
Requirements
This scenario will support both Ethernet and fibre channel connectivity. In order to implement this scenario, an HP BladeSystem c7000 enclosure with one or more server blades and TWO Virtual Connect FlexFabric modules, installed in I/O Bays 1& 2 are required. In addition, we will require ONE or TWO external Network switches. As Virtual Connect does not appear to the network as a switch and is transparent to the network, any standard managed switch will work with Virtual Connect. The fibre channel uplinks will connect to the existing FC SAN fabrics. The SAN switch ports will need to be configured to support NPIV logins. Two uplinks from each FlexFabric module will be connected to the existing SAN fabrics.
Scenario 4 – Shared Uplink Set with Active/Active Uplinks and 802.3ad (LACP) – Ethernet, FCoE SAN - Windows 2008 R2 Hyper-V 84
Figure 91 - Physical View; Shows two Ethernet uplinks from Ports X5 and X6 on Module 1 and 2 to Ports 1 and 2 on each network switch. The SAN fabrics are also connected redundantly, with TWO uplinks per fabric, from ports X1 and X2 on module 1 to Fabric A and ports X1 and X2 to Fabric B.
Figure 92 - Logical View; the server blade profile is configured with Four FlexNICs and 2 FlexHBAs. NICs 1 and 2 are connected to VLAN-101-x, NICs 3 and 4 are connected to multiple networks VLAN­102-x through VLAN-105-x and VLAN-2100 through 2150-x, which are part of the Shared Uplink Sets, VLAN-Trunk-1 and VLAN-Trunk-2 respectively. The VLAN-Trunks are connected, at 10Gb, to a network switch, through Ports X5 and X6 on each FlexFabric Module in Bays 1 and 2. In addition, SAN Fabric FCoE_A connects to the existing SAN Fabric A through port X1 on Module 1 (Bay 1) and FCoE_B connects to the existing SAN Fabric B through port X1 on Module 2 (Bay 2)

Installation and configuration
Switch configuration
Appendices A and B provide a summary of the commands required to configure the switch in either a Cisco or HP Networking (with both ProCurve and Comware examples). The configuration information provided in the appendices assumes the following information:
The switch ports are configured as VLAN TRUNK ports (tagging) to support several VLANs.
All frames will be forwarded to Virtual Connect with VLAN tags. Optionally, one VLAN could be configured as (Default) untagged, if so, then a corresponding vNet within the Shared Uplink Set would be configured and set as “Default”.
Note: when adding additional uplinks to the SUS, if the additional uplinks are connecting from the same FlexFabric module to the same switch, in order to ensure all the uplinks are active, the switch ports will need to be configured for LACP within the same Link Aggregation Group.
The network switch port should be configured for Spanning Tree Edge as Virtual Connect appears to the switch as an access device and not another switch. By configuring the port as Spanning Tree Edge, it allows the switch to place the port into a forwarding state much quicker than otherwise, this allows a newly connected port to come online and begin forwarding much quicker.
The SAN connection will be made with redundant connections to each Fabric. SAN switch ports connecting to the FlexFabric module must be configured to accept NPIV logins.
Configuring the VC module
Physically connect Port 1 of network switch 1 to Port X5 of the VC module in Bay 1 Physically connect Port 2 of network switch 1 to Port X6 of the VC module in Bay 1 Physically connect Port 1 of network switch 2 to Port X5 of the VC module in Bay 2 Physically connect Port 2 of network switch 2 to Port X6 of the VC module in Bay 2
Note: if you have only one network switch, connect VC ports X5 and X6 (Bay 2) to an alternate port on the same switch. This will NOT create a network loop and Spanning Tree is not required.
Physically connect Ports X1/X2 on the FlexFabric in module Bay 1 to switch ports in SAN Fabric A Physically connect Ports X1/X2 on the FlexFabric in module Bay 2 to switch ports in SAN Fabric B
VC CLI commands
Many of the configuration settings within VC can also be accomplished via a CLI command set. In order to connect to VC via a CLI, open an SSH connection to the IP address of the active VCM. Once logged in, VC provides a CLI with help menus. Through this scenario the CLI commands to configure VC for each setting will also be provided.
Configuring Expanded VLAN Capacity via GUI
Virtual Connect release 3.30 provided an expanded VLAN capacity mode when using Shared Uplink Sets, this mode can be enabled through the Ethernet Settings tab or the VC CLI. The default configuration for a new Domain install is “Expanded VLAN Capacity” mode, Legacy mode is no longer available and the Domain cannot be downgraded.
To verify the VLAN Capacity mode
On the Virtual Connect Manager screen, Left pane, click Ethernet Settings, Advanced
Settings
Select Expanded VLAN capacity Verify Expanded VLAN Capacity is configured and Legacy VLAN Capacity is greyed out.
Note: Legacy VLAN mode will only be presented if 1Gb Virtual Connect Modules are present, in which case the domain would be limited to Firmware version 3.6x.
Scenario 4 – Shared Uplink Set with Active/Active Uplinks and 802.3ad (LACP) – Ethernet, FCoE SAN - Windows 2008 R2 Hyper-V 86
Configuring Expanded VLAN Capacity via CLI
The following command can be copied and pasted into an SSH based CLI session with Virtual Connect;
# Set Expanded VLAN Capacity set enet-vlan -quiet VlanCapacity=Expanded
Figure 93 - Enabling Expanded VLAN Capacity
Note: if a 1Gb VC Ethernet module is present in the Domain, Expanded VLAN capacity will be greyed
out, this is only supported with 10Gb based VC modules. Also, once Expanded VLAN capacity is selected, moving back to Legacy VLAN capacity mode will require a domain deletion and rebuild.
Defining a new Shared Uplink Set (VLAN-Trunk-1)
Connect Ports X5 and X6 of FlexFabric module in Bay 1 to Ports 1 and 2 on switch 1 Create a SUS named VLAN-Trunk-1 and connect it to FlexFabric Ports X5 and X6 on Module 1
On the Virtual Connect Home page, select Define, Shared Uplink Set Insert Uplink Set Name as VLAN-Trunk-1 Select Add Port, then add the following port;
o Enclosure 1, Bay 1, Port X5 o Enclosure 1, Bay 1, Port X6

Note: Optionally, if one of the VLANs in the trunk to this shared uplink set were configured as Native
or Untagged, you would be required to “edit” that VLAN in the screen above, and configure Native as TRUE. This would need to be set for BOTH VLAN-Trunk-1 and VLAN-Trunk-2.
Defining a new Shared Uplink Set (VLAN-Trunk-2)(Copying a Shared Uplink Set)
The second Shared Uplink Set could be created in the same manner as VLAN-Trunk-1 however; VC now provides the ability to COPY a VC Network or Shared Uplink Set.

Scenario 4 – Shared Uplink Set with Active/Active Uplinks and 802.3ad (LACP) – Ethernet, FCoE SAN - Windows 2008 R2 Hyper-V 91
Note: In this scenario we have created two independent Share Uplink Sets (SUS), each originating from the opposite FlexFabric Modules, by doing so we provide the ability to create separate and redundant connections out of the Virtual Connect domain. When we create the server profiles, you will see how the NICs will connect to VLANs accessed through the opposite VC module, which provides the ability to create an Active / Active uplink scenario. Alternatively, we could have created a single SUS and assigned both sets of these uplink ports to the same SUS, however, this would have provided an Active/Standby uplink scenario, as shown in Scenario 5.

NICs 1&2 should be connected to networks VLAN-101-x, NICs 3&4 should be connected to networks VLAN102-x through VLAN105-x and VLAN-2100-x through VLAN-2150-x. FCoE SAN fabrics are connected to, Port 1 - FCoE_A and Port 2 - FCoE_B.
Defining a Server Profile via CLI
The following command(s) can be copied and pasted into an SSH based CLI session with Virtual Connect
# Create Server Profile App-1 add profile App-1 -nodefaultfcconn -nodefaultfcoeconn set enet-connection App-1 1 pxe=Enabled Network=VLAN-101-1 SpeedType=Custom Speed=1000 set enet-connection App-1 2 pxe=Disabled Network=VLAN-101-2 SpeedType=Custom Speed=1000 add enet-connection App-1 pxe=Disabled add server-port-map-range App-1:3 UplinkSet=VLAN-Trunk-1 VLanIds=102-105,2100­2150 add enet-connection App-1 pxe=Disabled add server-port-map-range App-1:4 UplinkSet=VLAN-Trunk-1 VLanIds=102-105,2100­2150 set enet-connection App-1 3 SpeedType=Preferred set enet-connection App-1 4 SpeedType=Preferred add fcoe-connection App-1 Fabric=FCoE_A SpeedType=4Gb add fcoe-connection App-1 Fabric=FCoE_B SpeedType=4Gb poweroff server 1
assign profile App-1 enc0:1 Note: The “add server-port-map-range” command is new to VC firmware release 3.30 and can be used to map many VLANs to a server NIC, in a single command. Prior releases would have required one command to create the NIC and one additional command per VLAN mapping added. This command will make profile scripting much easier, less complicated and quicker.
Note: The speed of the NIC and SAN connections, as well as the MAC and WWN. Also, note that the FCoE connections are assigned to the two SAN fabrics created earlier and use ports LOM:1-b and LOM:2-b.

Note: “Server VLAN ID” and “Untagged” boxes can be edited. One network per port could be marked
as “Untagged’, in which case the server would not be configured for tagging on that VLAN. It is also possible to change the VLAN ID that is presented to the server (VLAN translation), in which case the communications between Virtual Connect and the network would be the VLAN ID in grey, if the Server VLAN ID box to the right were changed, VC would communication with the server on the new VLAN ID, providing a VLAN translation function. VLAN translation could be a very useful feature, in the event that VLAN renumbering is required within the datacenter. The network VLAN numbers and Shared Uplink Set configurations could be changed to reflect the new VLAN IDs used, however, the old VLAN IDs could still be presented to the server providing the ability to delay or eliminate the need to change the VLAN ID used within the server/vSwitch.

Review
In this scenario we have created Two Shared Uplink Sets (SUS), providing support for many VLANs. Uplinks originating from each FlexFabric Module connect to each SUS, by doing so we provide redundant connections out of the Virtual Connect domain. As multiple uplinks are used for each SUS, we have also leveraged LACP to improve uplink performance. In this scenario, all uplinks will be active. We also create two FCoE SAN Fabrics.
We created a server profile, with FOUR NICs. Two connected to the same VLAN (101), Port 1 connects to VLAN-101-1 and Port 2 connects to VLAN-101-2, which provides the ability to sustain a link or module failure and not lose connection to the network. VLAN-101-1 and VLAN-101-2 are configured to support VLAN 101, frames will be presented to the NIC(s) without VLAN tags (untagged), these two NICs are connected to the same VLAN, but taking a different path out of the enclosure.
Network Ports 3 and 4 were added, these NICs will be connected to “Multiple Networks” and each NIC will then be configured for networks VLAN-102-x through VLAN-105-x and networks VLAN-
Scenario 4 – Shared Uplink Set with Active/Active Uplinks and 802.3ad (LACP) – Ethernet, FCoE SAN - Windows 2008 R2 Hyper-V 97
2100-x through VLAN-2150-x. As these networks are tagging, frames will be presented to the server with VLAN tags. NICs 3 and 4 will be teamed and connected to a Hyper-V virtual switch. VLAN tagged frames for these networks will be forwarded to the Virtual switch and then passed on to the appropriate Virtual Machine, VLAN tags will be removed as the frames are passed to the virtual machine. NICs 3 and 4 had their speed set to Auto, as NICs 1 and 2 were set to 1Gb, NICs 3 and 4 received 5Gb of bandwidth. As the networks had a maximum speed configured for 8Gb, the maximum speed for all NICs is 8Gb.
Additionally, FCoE port 1 is connected to SAN fabric FCoE_A and FCoE SAN port 2 is connected to SAN Fabric FCoE_B, providing a multi-pathed connected to the SAN.
The FCoE SAN fabric connects to each SAN fabric over a pair of uplinks per module. SAN logins are distributed across the multiple paths.
Results – Windows 2008 R2 Networking Examples
We have successfully configured FlexFabric with two shared uplink sets and redundant SAN fabrics. We have created a server profile with FOUR NICs, two connected to VLAN 101 and TWO connected to multiple tagged VLANs. We also configured SAN fabrics using the FCoE connections created within the profile.
Although both Ethernet and Fibre channel connectivity is provided by the CNA used in the G7 and Gen 8 servers; each capability (LAN and SAN) is provided by a different component of the adapter, they appear in the server as individual network and SAN adapters.
Figure 104 - Example of Emulex's OneCommand Manager Utility (formerly known as HBA Anywhere). Note that there are 3 Ethernet personalities and one FCoE personality per port, as configured in the server profile.
The following graphics show a Windows 2008 R2 server with FOUR FlexNICs configured, two at 1Gb and two at 5Gb. You will also notice that Windows believes there are 6 NICs within this server. However, only four NICs are currently configured within FlexFabric, the extra NICs are offline and could be disabled. If we did not require SAN connectivity on this server, the FCoE connections could be deleted and the server would then have 8 NIC ports available to the OS.
Note: the BL465c G7 and BL685c G7 utilize an NC551i chipset (BE2), whereas the BL460c G7, BL620c G7 and BL680c G7 utilize an NC553i chipset (BE3) and the Gen 8 blades typically have a NC554 adapter which also utilizes the BE3 chipset. Both the BE2 and BE3 chipsets share common drivers and firmware.

Figure 105 - Windows 2008 R2 Network Connections (4 Connections Active)
Note: The NICs that are not configured within VC will appear with a red x as not connected. You can
go into Network Connections for the Windows 2008 R2 server and disable any NICs that are not currently in use. Windows assigns the NICs as NIC 1-6, whereas three of the NICs will reside on LOM:1 (a,c &d)and three on LOM:2 (a,c &d). You may need to refer to the FlexFabric server profile for the NIC MAC addresses to verify which NIC is which.

Figure 107 - Windows 2008 R2 Network Connection Status
Note: In windows 2003 the NIC speeds may not be shown accurately when speeds are configured in
100MB increments above 1Gb. ie: if a NIC is configured for 2.5Gb it will be displayed in Windows 2003 as a 2Gb NIC. Windows 2008 does not have this limitation. In addition, as Virtual Connect 4.01 now provides the Min/Max network speed setting, even though we set the NIC to 1 and 5Gb, and set the maximum to 8Gb, the NIC displays the speed of 8Gb.
Scenario 4 – Shared Uplink Set with Active/Active Uplinks and 802.3ad (LACP) – Ethernet, FCoE SAN - Windows 2008 R2 Hyper-V 99
Figure 108 - Windows 2008 R2, Device Manager, SIX NICs are shown, however, we have only configured four of the NICs and two FCoE HBAs.
The following graphics provides an example of a Windows 2008 R2 server with four NICs connected to the network, initially each NIC has its own TCP/IP address, alternatively, NICs could be teamed to provide NIC fail-over redundancy. In this scenario we will create two teams, one for the management network (VLAN 101) and one for the Virtual guest networks (VLANs 102 through 105 and VLANs 2100 through 2150). If an active uplink or network switch were to fail, Virtual Connect would fail-over to the standby uplink. In the event of a Virtual Connect FlexFabric module failure,
the server’s NIC teaming software would see one of the NICs go offline, assuming it was the active
NIC, NIC teaming would fail-over to the standby NIC.
Figure 109 – Two NICs for Profile App-1are connected to the network through VLAN-101 and two NICs are connected to support all other VLANs. Those VLANs are tagged and no DHCP server is present on that network.
