GbE Interconnect Switches

Two GbE Interconnect Switches in the ProLiant BL p-Class server blade enclosure provide switch redundancy and redundant paths to the network ports on the server blades.

Each GbE Interconnect Switch has two Gigabit and two 10/100 Ethernet uplink ports and direct connections to two of the four network controllers on each server blade. The four network controllers one each server blade are NIC1, NIC2, NIC3, and Integrated Lights-Out (iLO). NIC1 is Preboot eXecution Environment (PXE)-enabled. Each pair of GbE Interconnect Switches consolidates up to thirty-two 10/100 Ethernet controllers on eight servers into one-to-four Gigabit ports and one-to-four 10/100 uplink port on the back of the system. This design eliminates up to 31 network cables from the back of the server blade enclosure.

NOTE: Refer to the Compaq ProLiant BL p-Class System Setup and Installation Guide for more information about Integrated Lights-Out (iLO) management and the Preboot eXecution Environment (PXE).

Redundant Crosslinks

The two GbE Interconnect Switches are connected through redundant 100-Mb/s crosslinks. These two crosslinks provide an aggregate throughput of 200 Mb/s for traffic between the GbE Interconnect Switches.

Introduction

Redundant Paths to Servers

The three 10/100 NIC ports and the one iLO controller on each server are routed through the enclosure backplane to different GbE Interconnect Switches. PXE NIC1 and NIC2 on each server blade are routed to Switch A. NIC 3 and iLO on each server blade are routed to Switch B. This configuration provides redundant paths to each server.

NOTE: On a heavily used system, using a single uplink port for all 24 NICs and 8 iLOs can cause a traffic bottleneck. For example, if uplink 1 on Switch A is the only uplink used, all traffic to and from NIC 3 and the iLO on any of the server blades must travel over the crosslinks between Switch A and Switch B. The crossover links are intended as a failover route on the switch management link and should not be used as a primary path. For optimum performance, use the uplink ports from both GbE Interconnect Switches.

Supported Technologies

The ProLiant BL p-Class GbE Interconnect Switch supports the following technologies. Refer to Chapter 3 and Chapter 4 for more details on these features.

Introduction

Layer 2 Based Packet Forwarding

The ProLiant BL p-Class GbE Interconnect Switch uses 10/100/1000 Gigabit Layer 2 switching technology. Layer 2 refers to the Data Link layer of the Open Systems Interconnection (OSI) model, which is concerned with moving data packets across a network by enforcing Carrier Sense Multiple Access with Collision Detection (CSMA/CD). This layer performs the following tasks:

• Ethernet packet framing

• MAC addressing

• Physical medium transmission error detection

• Medium allocation (collision avoidance)

• Contention resolution (collision handling)

Layer 2 switching technology allows the GbE Interconnect Switch to look into data packets and redirect them based on the destination MAC address. This reduces traffic congestion on the network because packets, instead of being transmitted to all ports, are transmitted to the destination port only.

IEEE 802.1Q Based Virtual Local Area Network

The ProLiant BL p-Class GbE Interconnect Switch provides support for up to sixty-four

802.1Q Virtual Local Area Networks (VLANs) for server grouping and isolation. A VLAN is

a network segment configured according to a logical scheme rather than a physical layout. VLANs can be used to combine any collection of LAN segments into an autonomous user group that appears as a single LAN. VLANs also logically segment the physical network into different broadcast domains so that packets are forwarded only between ports within the VLAN. This technology enhances performance by conserving bandwidth and improves security by limiting traffic to specific domains.

Example 1-1: You may want to isolate the server blade iLO ports from the rest of the NICs. The iLO ports on Interconnect Switch B can be assigned to their own VLAN and go to a dedicated uplink or share an uplink using VLAN tagging. Refer to the “Configuring VLANs” section in Chapter 3 or Chapter 4 for more information.

Spanning Tree Protocol

The GbE Interconnect Switch supports the Spanning Tree Protocol (STP), which allows the blocking of links that form loops between switches in a network. When multiple links between switches are detected, a primary link is established. Duplicated links are blocked from use and become standby links. If the primary link fails, the standby link is activated. Refer to Appendix D for more information.

Simple Network Management Protocol and Remote Monitoring

Each GbE Interconnect Switch can be configured and monitored remotely from a Simple Network Management Protocol (SNMP)/Remote Monitoring (RMON)-based network management station. The GbE Interconnect Switch supports industry-standard SNMP Management Information Bases (MIBs), proprietary Compaq Switch MIBs, and RMON groups 1 (Statistics), 2 (History), 3 (Alarm), and 9 (Event) for fault detection, configuration, and monitoring of switch functionality.

To secure the management interface, the switch administrator can configure community strings with various levels of access. Access can be restricted to a limited number of management stations by configuring a list of IP addresses of those stations that can access the GbE Interconnect Switch. Refer to Appendix E for more information.

Port Mirroring

The GbE Interconnect Switch allows you to mirror a port to another port for network monitoring and troubleshooting purposes. This technology offers a way for network packet analyzers to view the traffic moving through the GbE Interconnect Switches by providing a copy of the traffic that is currently being passed through any other port. The packets are normally sent to a network packet analyzer or other monitoring device attached to the mirror port.

Introduction

Trunking

The GbE Interconnect Switch port trunking feature allows several ports to be grouped together and act as a single logical link called a trunk. This feature provides a bandwidth that is a multiple of the bandwidth of a single link. It also improves reliability since a configurable way of load balancing is automatically applied to the ports in the trunked group. A link failure within the group causes the network traffic to be directed to the remaining links in the group.

Trivial File Transfer Protocol Support

Trivial File Transfer Protocol (TFTP) support allows the GbE Interconnect Switch firmware to be upgraded by downloading a new firmware file from a TFTP server to the GbE Interconnect Switch. A configuration file can also be loaded into a GbE Interconnect Switch from a TFTP server, configuration settings can be saved to the TFTP server, and a history log can be uploaded from the switch to the TFTP server.

Storage and Forward Switching Scheme

The ProLiant BL p-Class GbE Interconnect Switch provides a storage and forward switching scheme that allows each packet to be buffered (stored) before it is forwarded to its destination. While this method creates latency, it improves reliability in a heavily used interconnect switch. Packets that cannot be forwarded are saved immediately, rather than dropped, so that packets behind them are less likely to be dropped in periods of heavy usage.

Introduction

IEEE 802.1p Based Class of Service for Packet Prioritization

Class of Service (CoS) for packet prioritization allows switch administrators to set priority levels on the GbE Interconnect Switch for forwarding packets based on the priority setting information in the packets. The GbE Interconnect Switch supports four classes of traffic (buffers or queues) for implementing priority and allows administrators to map eight priority levels to the four classes. Traffic from a specific server port can be given priority over packets from other devices according to this range of priority levels. For example, with multiple packets in a buffer, the packet with the highest priority would be forwarded first, regardless of when it was received.

Internet Group Management Protocol Snooping

Internet Group Management Protocol (IGMP) snooping, when enabled and configured properly, manages multicast traffic in a GbE Interconnect Switch by allowing directed switching of the IP multicast traffic. The GbE Interconnect Switch can use IGMP Snooping to configure ports dynamically, so that IP multicast traffic is forwarded only to those ports associated with IP multicast hosts.

IGMP Snooping allows the GbE Interconnect Switch to recognize IGMP queries and reports sent between network stations or devices and an IGMP host that belong to a specific multicast group. When enabled for IGMP Snooping, the GbE Interconnect Switch can open or close a port to a specific device based on IGMP messages passing through the module. This feature further limits unnecessary broadcasts.

Dynamic Host Configuration Protocol or Bootstrap Protocol

By default, the GbE Interconnect Switch is configured to obtain an IP address from a Dynamic Host Configuration Protocol (DHCP) or Bootstrap Protocol (BOOTP) server during the boot process. The IP settings can also be manually configured by means of the console interface. The IP settings are also configurable from other interfaces, such as the Web, but because the connection is based on an IP address for these interfaces, users will have to reconnect with the newly assigned IP address.

Setting Up and Installing the GbE Interconnect Switch

Overview

This chapter describes how to set up and install the ProLiant BL p-Class GbE Interconnect Switches and the interconnect modules.

The setup and installation process includes the following tasks:

1. Installing the GbE Interconnect Switches and interconnect modules

2. Planning the GbE Interconnect Switch configuration

3. Cabling the GbE Interconnect Switch to the network

4. Powering up the GbE Interconnect Switch

5. Accessing the GbE Interconnect Switch

6. Logging on and configuring the GbE Interconnect Switch

Installing the GbE Interconnect Switches and Interconnect Modules

This section describes how to install the hardware in a new GbE Interconnect Switch deployment, a replacement for an existing GbE Interconnect Switch, or an upgrade from an RJ-45 Patch Panel.

IMPORTANT: Record the switch MAC address printed on the MAC address label attached to your GbE Interconnect Switch. The MAC address can be used to find the IP address from a DHCP server.

Installation Guidelines

Observe the following guidelines:

• Always install GbE Interconnect Switches in pairs. Each server blade enclosure requires

two GbE Interconnect Switches for proper connectivity. Do not mix the network interconnect environment. Always install the same type of device (either the Compaq ProLiant BL p-Class C-GbE Interconnect Kit, Compaq ProLiant BL p-Class F-GbE Interconnect Kit, or RJ-45 Patch Panels).

IMPORTANT: Be sure that the interconnect modules are fully seated. The latch/handle will drop into place when the module is firmly seated.

Replacing an Existing GbE Interconnect Switch

CAUTION: Removing an RJ-45 Patch Panel from a powered enclosure will result in the loss

of network communications between the server blade and the network infrastructure.

IMPORTANT: If you are replacing an existing GbE Interconnect Switch or upgrading from an RJ-45 Patch Panel, and have strict security requirements:

• Do not cable the GbE Interconnect Switch until after configuration.

• Connect the GbE Interconnect Switch to the optional Diagnostic Station. The Diagnostic Station

enables you to power up, configure, and diagnose a ProLiant p-Class server blade or a ProLiant p-Class GbE Interconnect Switch outside of the rack environment.

To replace an existing GbE Interconnect Switch:

1. If possible, save the configuration file to a TFTP server for later retrieval. Refer to the

“Saving Settings to a TFTP Server” section in Chapter 3 (console management interface) and “Saving Settings to TFTP Server” in Chapter 4 (Web-based management interface).

2. On the front side of the ProLiant BL p-Class server blade, release the ejector lever for the

GbE Interconnect Switch.

3. Pull down on the ejector lever to unlock the GbE Interconnect Switch from the enclosure.

Setting Up and Installing the GbE Interconnect Switch

4. Slide the GbE Interconnect Switch out of the communication bay.

5. Slide the new GbE Interconnect Switch fully into the communication bay.

6. Close the ejector lever.

7. If you saved the configuration file to a TFTP server, download the configuration. Refer to the “Downloading Configuration File from a TFTP Server” section in Chapter 3 (console management interface) and “Downloading a Configuration File on a TFTP Server” in Chapter 4 (Web-based management interface).

Upgrading from RJ-45 Patch Panels

CAUTION: Removing a GbE Interconnect Switch from a powered enclosure will result in the

loss of network communications between the server blade and the GbE Interconnect Switch.

1. From the front side of the ProLiant BL p-Class server blade enclosure, unlock the ejector lever and slide out the Patch Panels from the left and right communication bays.

2. From the rear side of the server blade enclosure, slide out the top and bottom patch panel RJ-45 modules (four total) from the left and right module bays and unplug the cables.

3. From the rear side of the server blade enclosure, insert the new interconnect modules (two total) that came with the GbE Interconnect Switches into the top-left and top-right module bays.

4. From the front side of the server blade enclosure, slide the GbE Interconnect Switch into the left communication bay.

5. Lock the ejector lever.

6. Repeat steps 4 and 5 to install the second GbE Interconnect Switch in the right communication bay.

Planning the GbE Interconnect Switch Configuration

Before you configure the GbE Interconnect Switch, Compaq recommends that you plan the configuration. As you plan, consider your default settings, security issues and privileges, and whether you want to configure each GbE Interconnect Switch manually or configure multiple GbE Interconnect Switches at the same time.

Default Settings

The GbE Interconnect Switches ship with a default configuration in which all ports are enabled and assigned a default virtual LAN (VLAN) with a VLAN ID (VID) equal to 1. This default configuration simplifies your initial setup by allowing you to use a single uplink cable (from any external Ethernet connector) to connect your server blade enclosure to your network. You need to assess your particular server environment to determine any requirements for other considerations.
