Introduction

Product introduction

The EMC® VNX VG2/VG8 servers are network-attached storage (NAS) gateways that connect to EMC Symmetrix arrays or both.

In the VG2 and VG8 systems, a blade (or Data Mover) is a logical identifier that is defined as a CPU module with associated I/O modules.

The VG2 system is equipped with one or two blades; the VG8 system has two to eight blades. If two blades are equipped, the NAS installation software automatically configures one blade as a standby for high availability.

Note: This document uses the terms blade and Data Mover interchangeably.

Each VG2/VG8 system can have one or two Control Stations.

A fabric-connected VNX gateway is cabled to one or more Fibre Channel (FC) switches or Fibre Channel over Ethernet (FCoE) switches by using fiber-optic cables and small form-factor pluggable (SFP) optical modules. The VNX gateway then connects through the Fibre Channel fabric to one or more arrays.

Other servers may also connect to the arrays through the fabric. You can use a single switch, or for added redundancy, you can use two switches. The VNX server can be installed anywhere in the fabric as long as it has a path to the storage array.

(DMX™, VMAX™, or VMAXe™) or VNX storage

A direct-connected VNX gateway is directly cabled to the storage area network (SAN) ports of the storage processors (SPs) of a storage array by using fiber-optic cables and SFPs. Other hosts can connect to the remaining SAN ports of the array, either directly or through a Fibre Channel switch. FCoE is not supported for direct-connected gateways.

If you are connecting the VNX gateway to more than one array, the gateway requires one storage array on which to load the VNX operating environment (VNX OE) and configure for booting the blades. This primary array should be the highest-performance system and must be set up first. The other arrays cannot be used to boot the blades and must be configured after the other setup steps are complete.

If the VNX configuration includes a Symmetrix array, the Symmetrix system should always be the boot array. Advanced Symmetrix features, such as Symmetrix Remote Data Facility Symmetrix array. Symmetrix DMX, Symmetrix VMAX, and Symmetrix VMAXe arrays are supported.

The Celerra Network Server Concepts Guide contains an overview of VNX servers. The Celerra Network Server System Operations technical module provides information on operating a VNX server.

The customer may have ordered the system with an EMC cabinet. Systems ordered with a cabinet have all components installed in the cabinet and most cables connected at the factory. Otherwise, you will install the individual system components in an existing cabinet at the customer’s facility.

(SRDF®), are supported only when the VNX gateway boots from the

EMC VNX VG2/VG8 Gateway Configuration Setup Guide

Page 21

Setup process overview

Installation and configuration of a VNX VG2/VG8 gateway is typically done in three phases:

◆ Phase 1: Plan the installation and collect configuration information from the

customer. The customer completes site preparation.

◆ Phase 2: Cable hardware to the customer’s SAN, local area network (LAN), and

power system; install the software; and configure the Control Station and ConnectHome. At this point, the system is functional but cannot be used by clients to store and retrieve files.

◆ Phase 3: Configure client network connections, file systems, shares, exports, and

so on. When this phase is complete, the system is fully usable by clients. Instructions for Phase 3 of the setup process are presented in Chapter 10,

“Complete Phase 3 Installation.”

Multiple individuals from different EMC or authorized service provider organizations may work together to complete the different phases of the installation. If the individuals are not at the customer’s site at the same time, it is critical that they provide each other the information needed for each phase.

EMC CONFIDENTIAL

Introduction

Phase 1: Planning and data collection

The first phase starts when the customer agrees to the installation and ends when all of the required information has been collected. Missing information, such as IP addresses, can cause significant delays later in the installation process:

1. Follow the EMC Change Control Activity (CCA) process to obtain an approval for the VNX installation. The CCA requirements may be found on the NAS Support website or the EMC Services Partner website. An approved CCA will direct you as to where and how to obtain the correct version of EMC NAS software to use in the installation.

2. Review the VNX release notes for the version of EMC NAS software specified by the CCA for this installation. Release notes are available from the EMC

Powerlink

website. Pay special attention to any installation-related items.

3. Verify that the customer has completed all site preparation steps, including providing appropriate power and network connections.

4. If the VNX gateway is being connected to a new array, verify that the array has been installed and configured before starting to install the VNX gateway. Verify that the required revision of the array software is installed and committed.

5. Fill out the configuration worksheets with the customer.

6. Give the Phase 2 configuration information to the installer who will complete the next phase.

Setup process overview

Page 22

EMC CONFIDENTIAL

Introduction

Phase 2: Physical installation and initial configuration

The second phase includes physically installing the system if it did not ship in an EMC cabinet, cabling the system to the customer’s network, installing the NAS code, and configuring the Control Station and ConnectHome. The second phase is complete when the system successfully calls home and you have filled out the “Phase

2 completion hand-off worksheet” on page 282.

Always install and configure the system according to the instructions in this guide. Ensure that you follow the steps in the order given.

To install a VNX gateway:

1. Verify that you have received the required Phase 2 configuration information from the individual who completed Phase 1.

2. Verify that all required components are on site.

3. For systems that shipped without a cabinet, install the components in the customer's cabinet. Chapter 3, “Install Components in Customer’s Cabinet,” provides more details.

4. For systems that shipped without a cabinet, connect the system cables (Fibre Channel, network, and power cables). For factory-cabled systems, verify that the cables are connected correctly. Connect additional cables if necessary.

5. Power on the system and verify the software revisions. Install software as needed. You will need your service laptop computer.

6. Configure the primary Control Station 0 (CS 0).

7. Configure and test ConnectHome.

8. Enable licenses in the EMC Unisphere™ interface for features that you require (for example, Network File System (NFS)).

Introduction

Phase 3: Final configuration

The third and final phase includes all of the configuration required to make the VNX gateway available to clients. The specific steps depend on which services the customer purchased. For example, a customer may elect to have only one initial file system created, or may choose an advanced configuration with multiple file systems, advanced networking configurations, and so on.

The required and optional steps of Phase 3 are documented in Chapter 10, “Complete

Phase 3 Installation.”

Required for all configurations

The following steps are required for all configurations:

1. Configure storage.

2. Run the Setup Celerra Wizard to configure Control Station, blades, network services, and interfaces. Also, create file systems and share file systems. Create exports, netgroups, and users.

3. Generate SSL certificates.

Optional

The following steps are optional for all configurations:

◆ Add or remove arrays.

◆ Upgrade server software to correct a failure of the backend storage requirements

check.

◆ Configure EMC VNX Replicator™.

The third phase is complete when all planned configuration steps are complete and the customer has signed off the implementation phase.

Introduction

How setup works

This section explains how the setup process works. Use this information if you have problems with the setup process.

Note: Automated routines can zone the Fibre Channel (FC) switches and create the system LUNs on a VNX array. You must manually zone Fibre Channel over Ethernet (FCoE) switches.

Factory configuration

Boot array

All VNX gateways have the EMC NAS software loaded on the Control Station internal drive at the factory. Like other gateways, the NAS software is never installed on the array, even if the system is delivered in a cabinet from the factory with a VNX array.

The factory always loads the latest software on the Control Station at the time of manufacture. However, the installation can take place several months after the hardware was shipped, so it is very important to install the latest software version.

VNX server blades do not have any internal storage. They boot their operating environment from a designated area on a Symmetrix or VNX array. Although a VNX gateway can store data on several arrays, it always boots from one array, called the boot array in this guide.

The designated area on the array that stores the blade operating system and other related files is referred to as the system LUNs or sometimes control LUNs.

Note: Appendix F, “Manually Zone Switches and Configure System LUNs,” includes the

instructions for manually zoning switches and creating the system LUNs if the target array does not meet the auto-configuration requirements, or if the customer has specific policies that cannot be met by using auto-configuration, or if the array is connected to an FCoE switch.

The Control Station in the VNX VG2/VG8 gateways does not boot from the array. The Control Station stores copies of its configuration data on the array, but the Control Station boots from an internal disk drive. Therefore, you can boot the Control Station of the VNX gateway even if there is no connection to the boot array.

Because the blades boot from the array, any problem with the connection between the blade and the boot array can prevent the blade from booting. Appendix D, “Resolve

Blade Boot Failures,” explains what to do if the blades cannot boot.

VNX arrays When connected to an FC switch, a VNX boot array must be installed and can be

auto-configured during the installation. However, auto-configuration is not supported when the VNX boot array is connected to an FCoE switch.

For VNX arrays, the system LUNs can be created automatically during the VNX gateway setup process.

Symmetrix arrays A Symmetrix boot array must be installed and manually configured before installing

the VNX gateway. Symmetrix DMX, VMAX, and VMAXe are supported arrays for VNX gateways.

Also, EMC generates a new bin file to create the system LUNs. For more information, see:

Introduction

Installing software in the field

PXE booting blades

Assigned blade identifiers

To install the NAS software on the VNX gateway as part of a new installation, you need installation media with the correct software version. Do not use the NAS software media that shipped with the system—it may contain a software version that is out-of-date. The required software version should be verified as part of the Change Control Authorization (CCA) process prior to installation.

The Control Station runs an EMC-customized version of the Linux operating system. You can install the NAS software from authorized EMC NAS installation media.

When the correct NAS software version is installed on the Control Station, you power up the blades for the first time. The blades cannot boot from the array because the array does not have the EMC NAS software installed. Instead, the blades boot from the Control Station over the private LAN connections. This is called PXE (preboot execution environment) or network booting.

During this boot process, the blade BIOS and POST versions are automatically upgraded if needed.

The blade identifiers are based on the enclosure number. Blade enclosure 0 houses blades 2 and 3. (The Control Station reserves ID 0 and 1 for itself, and for this reason, the first blade has an ID of 2.) The right-most blade in a blade enclosure (viewed from the rear) has the lower blade number. Figure 6 on page 37 shows this detail.

A VG2 system has up to two blades (blades 2 and 3) in a single blade enclosure (enclosure 0). A VG8 system has between two and eight blades (housed in one, two, three, or four blade enclosures). In a VG8 system, enclosure 0 houses blades 2 and 3; enclosure 1 houses blades 4 and 5; and so on.

Configuring the private (internal) LAN

The VNX VG2/VG8 gateway uses two fully redundant private (internal) LANs for communication between the Control Stations, enclosure management modules, and blades. These private LANs use IP addresses in two subnets. A dynamic host configuration protocol (DHCP) service on the Control Station assigns addresses to each component on the private LANs. However, the address assigned to a component is always the same.

Note: During fresh installs of NAS software, the private LAN addresses can be changed, if required; otherwise, the installation program uses default addresses.

The default subnets are:

◆ 128.221.252.nnn — This subnet is the primary private LAN. It connects to the

ports (eth0) labeled A on the Control Stations and to the management module ports on the right side of the blade enclosures, when viewed from the rear.

◆ 128.221.253.nnn — This subnet is the backup private LAN. It connects to the port

(eth2) labeled B on the Control Stations and to the management module ports on the left side of the blade enclosures, when viewed from the rear.

◆ 128.221.254.nnn — This subnet is for the intelligent platform management

interface (IPMI) between two Control Stations. The IPMI enables one Control Station to monitor and reboot the other. The subnet consists of a crossover cable between ports labeled CS on the two Control Stations.

Blade 8 (optional) 8

Blade 9 (optional) 9

Note: Blade 3 is optional for the VG2 but required for the VG8. Blades 4–9 do not apply to the VG2.

It is best to change the internal IP addresses of the VNX gateway from the system defaults during installation. Changing the private IP addresses after the installation is a complex process that involves blade downtime. Appendix B, “Change IP

Addresses,” provides steps to change the VNX gateway internal IP address after

installation.

If the customer is already using these default subnets in their public network, the private LAN addresses should be changed at the installation time. Even though the private LAN does not connect to the customer’s public LAN, the blades and Control Station connect to both networks.

Note: If a customer has multiple VNX gateways, each system can have the same set of private LAN addresses. A conflict occurs only if the same network exists in both the public and private LANs. All VNX gateways attached to the same VNX array must have unique network addresses in the Initiator Record Host IP Address field in the Unisphere interface to ensure that the Host display for those VNX gateways appears correctly.

During the Control Station configuration, you can accept the defaults or enter different addresses for the Control Station private LAN ports. The other components are automatically configured to match. The new private LAN addresses must:

◆ Use a subnet mask of 255.255.255.0.

◆ Be in a subnet that is not used in the customer’s public network.

Introduction

For example, if you set the primary private address for the Control Station (default

128.221.252.100) to 10.12.17.100, then the primary private addresses are set to:

◆ 10.12.17.2 for blade 2

◆ 10.12.17.4 for blade 4

◆ 10.12.17.50 for the enclosure 0 right-side management module

◆ 10.12.17.100 for Control Station 0

The same rules apply to the backup subnet.

“Private LAN worksheet” on page 280 provides details for the default addresses. If

you need to change the private LAN addresses, record the new values in this worksheet.

Zoning FC switches

Once the blades have been network-booted, the Control Station collects the World Wide Names (WWNs) of the Fibre Channel ports in the blades. A WWN identifies a port in a Fibre Channel fabric, much like a MAC address in an Ethernet network, and is based on the enclosure WWN seed value. The WWNs are used to zone the Fibre Channel switches.

When selected, the auto-configuration script automatically sets up the Fibre Channel switch zones by using single initiator zoning. The auto-configuration script configures each gateway blade with four zones (each blade port is zoned to one port on each SP).

The script prompts for the network address and login credentials of each switch. The setup script supports Fibre Channel switches from the following manufacturers: McDATA, Brocade, and Cisco. Refer to the EMC E-Lab™ Interoperability Navigator on Powerlink for supported firmware revisions of your switch. If a Fibre Channel switch works with the VNX gateway, then it will work with auto-configuration.

The setup script cannot automatically zone the FC switch if:

◆ The switch password is still set to its default value. Set the switch password to a

value other than the default before using the script.

◆ The switch contains uncommitted zones or configurations. Commit or delete

these zones or configurations before you continue. This prevents the setup script from overwriting any existing fabric zoning, or configurations the customer might want saved but has not committed to the configuration.

◆ The gateway system has a 10 Gb FCoE I/O module in slot 0 of the VNX blade

enclosures. See “Zoning FCoE switches” on page 28.

If the auto-configuration script cannot zone the customer’s Fibre Channel switches, or if the default zoning is not acceptable, then you can manually zone the switches. Manual zoning uses the administration program provided by the switch manufacturer.

The correct switch zoning enables the blades to communicate with the arrays over the Fibre Channel fabric. By default, each blade is zoned to each SP on a VNX array. For Symmetrix arrays (DMX, VMAX, and VMAXe), each blade is zoned to two different channel directors.

Note: You must manually zone the FC switch if you are using a Symmetrix array for the boot array. Appendix F, “Manually Zone Switches and Configure System LUNs,” provides information about manually zoning the FC switch.

Introduction

Zoning FCoE switches

Creating Host LUNs

The VNX VG2 and VG8 gateways can be connected to the following Fibre Channel over Ethernet (FCoE) switches: Connectrix MP-8000B (Brocade), Cisco Nexus 5010, and Cisco Nexus 5020. To connect to an FCoE switch, the gateways require a 10 Gb FCoE I/O module in slot 0 of the VNX blade enclosures.

Note: If connecting a Cisco switch, configure the switch parameter “no errdisable detect cause all” for optimal performance.

You must manually zone the FCoE switches (no auto-configuration script exists for zoning FCoE switches). Manual zoning uses the administration program provided by the switch manufacturer.

Note: Appendix F, “Manually Zone Switches and Configure System LUNs,” provides

information about manually zoning the FCoE switch.

The correct switch zoning enables the blades to communicate with the arrays over the Fibre Channel fabric. By default, each blade is zoned to each SP on a VNX array.

For information on FCoE switch configurations, refer to the EMC Techbook: Fibre Channel over Ethernet (FCoE) on the EMC Powerlink website.

Tab le 2 lists the Host LUN values that you need to use for the VNX. The LUNs must

be created and masked to the VNX unless you are using auto-configuration. Auto-configuration works for direct-connected gateways or fabric-connected gateways that connect to an FC switch. Gateways that are connected to an FCoE switch must be manually configured as described in

Switches and Configure System LUNs.”

After the switches are zoned, the Control Station can install the NAS software to the system LUNs on the boot array. This installation is part of the setup script running on the Control Station.

Note that a Control Station cannot copy data directly to an array. The Control Station does not have a Fibre Channel host bus adapter (HBA). Instead, the Control Station uses an EMC-proprietary system called network block service (NBS), which is explained in the following section.

Introduction

Understanding the network block service

Figure 1 Network block service

The network block service (NBS) enables the Control Station to access LUNs on an array. For example, the Control Station uses NBS to read and write its database information stored in the system (or control) LUNs, and to install NAS software on the array.

NBS data is sent from the Control Station to a blade over a private LAN connection. The blade then sends the data to the array over the Fibre Channel connection.

Figure 1 shows the physical path used for the virtual NBS connection.

Configuring dual Control Stations

An NBS client daemon on the Control Station communicates with the NBS server on the blades.

The Control Station must have at least one blade running normally and accessible over the local network to run any administrative commands. Administration is not possible without the NBS connection.

Array management traffic between the Control Station and the array does not use the NBS service.

A VNX VG2/VG8 gateway optionally has a second Control Station for high availability. At installation time, CS 0 is the primary CS, and CS 1 is the standby. After installation, CS 0 is always the active CS. If the primary CS fails, the standby becomes primary. The former standby remains primary until another failure or reboot. Therefore, at any time, depending on the circumstances, either CS may become primary.

Network connections to dual Control Stations can use IP aliasing. This enables the administrator to contact the primary Control Station with a consistent address, regardless of which physical Control Station is primary. The Celerra Network Server System Operations technical module provides details for IP aliasing instructions.

A complete software installation is first performed on CS 0 (CS 1 must be powered down and its power cable disconnected). When that installation is complete, you perform the software installation on CS 1. When the installation on the second Control Station is complete, CS 0 is primary and CS 1 is in standby mode. The software setup script prompts you about installing the secondary Control Station; it does not detect this automatically.

Introduction

Note: Both Control Stations must be running exactly the same version of the EMCNAS software. You should verify the software on both Control Stations, even if the first one you check has the correct version.

Booting blades from the array

Remaining setup steps

Unisphere interface

After the Control Station has installed the NAS software on the array, the blades are rebooted. This time, the blades boot from system LUN 0 on the array. During this boot process, the blade BIOS and POST versions are automatically upgraded if needed.

If Fibre Channel configuration problems exist, you would encounter them now. Problems such as incorrect zoning, incompatible switch software versions, or incorrect array initiator records can cause the boot to fail.

The remaining steps set the configuration values, and then create the user volumes. These steps are typically performed by using the Setup Celerra wizard in the EMC Unisphere interface. The Setup Celerra wizard walks you through the various settings—you can perform the same tasks by using the CLI. EMC recommends that you use the Setup Celerra wizard to prevent accidentally skipping a required setting.

Chapter 10, “Complete Phase 3 Installation,” provides information on the Setup

Wizard.

User tasks that require a user interface are performed by using the EMC Unisphere™ interface. The Unisphere interface replaces the Celerra Manager and Navisphere Manager interfaces of earlier releases. However, if the backend array is using FLARE release 29 or earlier, Navisphere Manager is required for some of the backend tasks.

Appendix I provides the procedures to perform these tasks.

VNX gateways and domain support

A domain is a group of EMC storage systems that are centrally administered. A VNX VG2/VG8 gateway cannot form or join a domain.

components

Verify that all components are on site. Components may already be installed in an EMC cabinet, or you may need to install them in the customer’s existing 19-inch NEMA rack. Most required parts are provided with the system, but some are shipped with particular components and others, like external LAN cables, are provided by the customer.

Verify that the following items are at the installation site before starting setup. For a system that was factory-installed in an EMC cabinet, most components are already mounted in the cabinet.

The VG2 has one blade enclosure. The VG8 has between one and four blade enclosures. Each blade enclosure includes:

◆ One or more of the following network Host Bus Adaptors (HBAs):

• I/O module with two 10 GbE optical ports

• I/O module with four 1 gigabit Ethernet (GbE) copper ports

• I/O module with two 1 GbE copper ports plus two 1 GbE optical ports

◆ One Fibre HBA in slot 0 of each blade:

• Fibre Channel (FC) I/O module with four 2/4/8 GbE ports

• FC I/O module with four 1/2/4 GbE ports

• Fibre Channel over Ethernet (FCoE) I/O module with two 10 GbE ports

Note: The maximum number of I/O modules in each blade for the VG2 is four; for the VG8, the maximum is five. The combination of I/O modules must be the same for each blade in a VNX VG2/VG8 gateway.

◆ One or two CPU modules per blade enclosure (for VG8, two CPU modules are

required in enclosure 0 with one or two CPU modules in the remaining enclosures)

◆ Two management modules per blade enclosure

◆ Two power supply/cooling modules per CPU module

◆ Mounting rails with hardware

modules

Each blade (also called a Data Mover) in an VG2/VG8 system has one CPU module and one or more I/O modules to provide backend and frontend connectivity. A management module provides ports for communication between the Control Stations and the blades.

A Fibre Channel (FC) I/O module in slot 0 of each blade provides two ports for either direct-connecting to the back-end storage array or connecting to an FC switch or tape backup device (Figure 12).

Two versions of this module support fibre speeds of either:

◆ 1, 2, or 4 Gb/s

◆ 2, 4, or 8 Gb/s

The default configuration includes the 2/4/8 Gb/s version of this module.

Your customer may have ordered a VNX or Symmetrix array with the VNX gateway, or your customer may already have the array. If your customer ordered the optional cabinet, the components are installed in the cabinet at the EMC factory.

The installation of the array is outside the scope of this guide. Refer to the VNX or Symmetrix installation documentation.

A working system requires a fully operational VNX array (for example, the VNX5300) and a cabinet.

Figure 20 shows an example of a VNX VG2 gateway (two blades and one Control

Station) with a CX4-120 storage array. Because components can have different depths, you should stack them within the cabinet to facilitate easy access to the rear.

Note: FCoE is not supported in a direct-connected system.

Step 2: Confirm site preparation

The following site preparation must be completed by the customer before you can install and set up a VNX VG2/VG8 gateway. Some steps differ depending on whether the system was installed in a cabinet at the factory or will be installed in the customer’s cabinet on site.

EMC CONFIDENTIAL

Before Installing

EMC factory-installed cabinet

Customer’s cabinet

If the VNX gateway was factory-installed in an EMC cabinet, confirm the following:

◆ Electrical wiring to accommodate the cabinet’s power cables is in place at the

facility.

◆ EMC cabinets include four 240-volt AC power cables. To support all

high-availability features, EMC recommends that you connect the power cables to two different circuits.

If the network server is being installed in the customer’s existing cabinet:

◆ Verify that the customer’s cabinet is a standard 19-inch NEMA cabinet, such as an

EMC cabinet.

Verify that the customer ’s cabinet has sufficient space for the network server. Vertical rack space is measured in units called “U.” One U equals 1.75 inches (4.45 centimeters). A maximum VNX VG2 gateway requires 4U of vertical space; a maximum VG8 gateway requires 10U of vertical space.

◆ Verify that the cabinet is deep enough to accommodate the components (at least

31 inches/79 centimeters). Verify the supplied rail kits fit the spacing between the front and rear channels in the cabinet.

◆ Verify that the customer’s cabinet has sufficient power for the network server. The

following values should be balanced between the four circuits. Each circuit should be able to carry the full load in case another circuit fails:

• Maximum VG2 configuration (two blades and two Control Stations) requires 790 V Amp

• Maximum VG8 configuration (eight blades and two Control Stations) requires 2360 V Amp

◆ Verify that the facility has adequate network connections for required subnets.

Each blade requires separate network connections.

Celerra Tools on Powerlink provides more information on space and power requirements.

All systems

For all systems:

◆ Verify that the array being used as the boot array is already installed and

configured. If you are installing a new array with the VNX gateway, complete the array installation first.

◆ Verify that there are at least two available ports on the FC or FCoE switch for each

blade. Check the EMC E-Lab Interoperability Navigator on Powerlink to verify that the switch is supported for the VNX gateway you are installing. This is not applicable for direct-connected VNX gateways.

Step 2: Confirm site preparation

Page 48

EMC CONFIDENTIAL

Before Installing

◆ Verify the switch or switches have available ports to connect to the array. The

FC/FCoE connections between a Symmetrix array and a switch used for the VNX gateway cannot be used for any other host computer. VNX arrays can share the connection between the switch and the array with other hosts. This is not applicable for direct-connected VNX gateway.

◆ Verify that the facility has adequate network connections for required subnets.

Each blade requires separate network connections:

• “Step 6: External network cables” on page 76 provides information for the cable and connector requirements for a fabric-connected VG2 system.

• “Step 5: External network cables” on page 87 provides information for the cable and connector requirements for a direct-connected VG2 system.

• “Step 6: External network cables” on page 110 provides information for the cable and connector requirements for a fabric-connected VG8 system.

• “Step 5: External network cables” on page 123 provides information for the cable and connector requirements for a direct-connected VG2 system.

◆ Verify that the supplied cables have the correct connectors for the customer’s

FC/FCoE switches (optical cables for FC switches; optical or active twinaxial cables for FCoE switches). This is not applicable for direct-connected VNX gateways.

Systems with Symmetrix arrays

Fabric-connected systems with VNX arrays

If you are connecting the VNX VG2/VG8 gateway to a Symmetrix array (DMX, VMAX, or VMAXe):

◆ Check the EMC E-Lab Interoperability Navigator on Powerlink to verify that the

array is supported and the required array software versions are installed.

◆ Verify that each of two different channel directors has at least one Fibre Channel

port (two ports total) for the exclusive use of the VNX VG2/VG8 gateway.

Verify that EMC has configured the Symmetrix array with the required hypervolumes for the VNX gateway volumes and user volumes. For more information, see:

http://www.cs.isus.emc.com/config/Products/ EMCProducts/Celerra/Celerra.htm

◆ You must manually zone the FC switch if you are using a Symmetrix array for the

boot array. Appendix F, “Manually Zone Switches and Configure System LUNs,” provides information about manually zoning the FC switch.

If you are connecting the VNX gateway to a fabric-connected VNX array:

◆ Check the EMC E-Lab Interoperability Navigator on Powerlink to verify that the

array is a supported model. Verify that the required array software versions are installed.

◆ Verify that all SAN ports on the array are connected to the Fibre Channel switch

or switches. If some SAN ports are not in use, verify that there are available switch ports to connect them.

◆ Verify that there are at least four unused disks available in the array (these are the

vault disks). The array must also have an available hot spare disk or another unused disk that can be configured as a hot spare.

◆ Verify that both SPs are up and functioning, that write cache is enabled, and that

existing LUNs are not trespassed or faulted.

If you are connecting the VNX gateway to a direct-connected VNX array:

◆ Verify that the array being used is already installed and configured. If you are

installing a new array with the VNX gateway, complete the array installation first.

◆ Check the EMC E-Lab Interoperability Navigator on Powerlink to verify that the

array is a supported model. Verify that the required array software versions are installed.

◆ Verify that one or two SAN ports on each array SP are available to connect to the

blades.

◆ Verify that there are at least four unused disks available in the array (these are the

vault disks). The array must also have an available hot spare disk or another unused disk that can be configured as a hot spare.

◆ Verify that both SPs are up and functioning, that write cache is enabled, and that

existing LUNs are not failed over.

EMC Access Logix™ is a licensed software option for a VNX array. If the customer does not already have Access Logix enabled for an existing array, a license may have been ordered with the VNX gateway system. If Access Logix is not enabled and a license was not included in the order, contact the EMC Software Refresh group to determine entitlement prior to enabling Access Logix.

Begin with the lowest component in the cabinet and work towards the top. The VNX gateway, FC/FCoE switches, and arrays do not have to be in the same cabinet.

If you are installing a new Symmetrix or VNX array at the same time, refer to the appropriate installation documentation for the array.

The relative position of the components within the rack is not critical as long as:

◆ Cables can reach connecting ports or receptacles

◆ Access to connections at the rear of the cabinet is possible

Note: Enclosures have different depths. You should stack enclosures within the cabinet to facilitate access to the rear of the components.

Ta bl e 4 provides information about the VG2/VG8 components and examples of

stacking these components.

IMPORTANT

Connect Cables for a Fabric-connected VG2

Step 1: Blade Fibre Channel cables

The figures in this section of the document contain logical drawings of cable connections. To view the physical port locations, see “Identifying blades and I/O

modules” on page 40.

Fibre Channel cables connect the I/O modules in the blades to the Symmetrix and VNX arrays through FC/FCoE switches. Each blade has two Fibre Channel ports that must be connected to both storage processors of the VNX array.

The Fibre Channel cables have not been connected.

Different switches use different cable connectors. The supplied optical cables always have LC connectors on both ends. If the customer’s switch needs different connectors, additional cables may have been ordered.

The cabling and zoning rules for a VNX gateway system are minimum requirements. You can have additional paths between the array and the blades, but you must observe the following blade limits:

◆ 16 paths per LUN for Symmetrix storage arrays

◆ 8 paths per LUN for VNX storage arrays

◆ 4 paths per LUN is recommended for most configurations

Use the “FC/FCoE cabling worksheet” on page 273 to record the ports you actually cable.

Arrange the cables so that a failed component can be removed without disconnecting other cables.

Use small form-factor pluggable (SFP) modules in the SP and I/O module ports to connect the Fibre Channel cables (see “SFP modules” on page 43).

The Fibre Channel connections from the blades to the switch or switches are always the same, regardless of the array to which you are connecting. Two switches are recommended for highest availability.

If you are using:

◆ Two switches, connect the cables as shown in Figure 23 on page 59.

◆ One switch, connect the cables as shown in Figure 24 on page 59.

The four-port Fibre Channel I/O module is available in two versions:

◆ 4 Gb/s supporting fibre speeds of 1, 2, or 4 Gb/s

◆ 8 Gb/s supporting fibre speeds of 2, 4, or 8 Gb/s

The two-port FCoE I/O module supports fibre speeds of up to 10 Gb/s.

Verify that the switch ports are configured for auto-negotiation (see switch documentation for steps to configure auto-negotiation). The FC/FCoE ports automatically adjust to the appropriate rate, depending on the rate of the attached client.

If the blades fail to boot from the array, you may have to manually force the Fibre Channel speed setting. If you must do this, set the switch ports to the highest speed (1, 2, 4, or 8 Gb/s) that the switch can support. Appendix D, “Resolve Blade Boot

Failures,” provides more information.

Connecting a Symmetrix array

For a Symmetrix array (DMX, VMAX, or VMAXe), you need two channel director ports dedicated to the VNX gateway system. These ports must be on different channel directors as shown in the examples in Figure 25 or Figure 26 on page 61.

EMC VNX VG2/VG8 Gateway Configuration Setup Guide

Figure 25 Example of Symmetrix channel directors connected to two switches

Note: The Symmetrix DMX, VMAX, and VMAXe directors may have different numbers of ports than shown in Figure 25.

To make connections to two switches for high availability as illustrated in the example in Figure 25:

1. Verify from the CCA activity or the Symmetrix administrator the channel director ports to use for the VNX gateway system.

2. Connect the specified channel director port to the first switch.

3. Connect the specified port on another channel director to the second switch.

4. Record the channel director ports you connected to the switch ports by using the

Figure 35 VNX5100 connected to two switches for high availability (example)

If all of the SAN ports on the array are already connected to the fabric, you need not change these connections. If the array has two available ports on each SP, the recommended practice is to cable these ports to the switches and dedicate them to the VNX gateway system.

If you are using two switches to connect a VNX5100 array, connect the cables as shown in the example in Figure 33.

The array SAN ports 2 and 3 are used in this example, but you can use any two ports on each SP:

1. Connect SP A slot 0, port 2 to switch A.

2. Connect SP B slot 0, port 2 to switch A.

3. Connect SP A slot 0, port 3 to switch B.

4. Connect SP B slot 0, port 3 to switch B.

5. Record the SP ports you connected to the switch ports by using the “FC/FCoE

The VNX gateway can connect to tape backup devices by using optical cables, either directly or through an FC/FCoE switch.

If you have an FC I/O module in the boot slot, use ports 2 and 3 to connect a tape device (Figure 39). If you have an FCoE I/O module in the boot slot, connect the tape device to any two ports of an FC I/O module in a different slot (Figure 40).

The ports sense the:

◆ Speed of the device they connect to and automatically adjust to the appropriate

speed (depending on the type of I/O module installed).

◆ Topology of the Fibre Channel network they are connected to and automatically

configure for arbitrated loop or switched fabric as needed.

To connect the FC I/O module:

1. Connect one end of the appropriate cable to the FC I/O module in blade 2 (see examples in Figure 39 and Figure 40).

Step 5: Private LAN cables

The private (internal) LAN cables connect the Control Station to the blades through the blade enclosure’s management modules. These cables and switches make up a private network that does not connect to any external network.

The blade enclosure has two management modules, which are redundant. If module A fails, module B assumes control of the private network. The Control Stations communicate to the blades through the management modules.

Figure 41 shows VG2 management module with the private LAN ports 0, 1, and 2.

Figure 41 VG2 management modules

Do not connect any other cables to the management modules, such as public LAN cables, or array management port cables.

To connect the private LAN cables:

1. Connect an RJ-45 Ethernet cable from port 1 on management module A to the port labeled A on CS 0 (cable 1 in Figure 42).

2. Connect an RJ-45 Ethernet cable from port 1 on management module B to the port labeled B on CS 0 (cable 2 in Figure 42).

3. For dual Control Station systems, connect an RJ-45 Ethernet cable from port 2 on management module A to the port labeled A on CS 1 (cable 3 in Figure 42).

4. For dual Control Station systems, connect an RJ-45 Ethernet cable from port 2 on management module B to the port labeled B on CS 1 (cable 4 in Figure 42).

Step 6: External network cables

The external network cables connect clients of the VNX system to the I/O modules in the blades. Another external network cable connects the Control Station to the customer’s network for remote management of the system.

Note: For successful blade failover, you must establish identical network connections for the primary and standby blades.

The external network cables are provided by the customer. The category and connector type of the cable must be appropriate for use in the customer network.

The VG2 system has these network I/O module types:

◆ Two 10 GbE optical ports (Figure 14 on page 42).

◆ Four 1 GbE copper 10/100/1000 ports (Figure 15 on page 42).

◆ Two 1 GbE copper 10/100/1000 ports and two optical 1 GbE ports (Figure 16 on

page 43).

The copper Ethernet network ports on the I/O modules support 10, 100, or 1000 megabit connections and have standard RJ-45 connectors.

The optical Gigabit Ethernet network ports have LC optical connectors and support 50 or 62.5 micron multimode optical cables. SFP modules are installed in the ports at the factory (see “SFP modules” on page 43 for more information).

Any advanced configuration of the external network ports is beyond the scope of this setup guide. The VNX system supports many network configuration options such as Ethernet channels, link aggregation, and Fail-Safe Networks (FSNs).The Configuring

and Managing Celerra Networking and Configuring and Managing Celerra Network High Availability technical modules provide more information.

Connect the external network cables as follows:

1. Connect the Ethernet LAN cable (labeled MGMT) on the first CS to the customer’s 10/100 Ethernet network that will be used to manage the VNX gateway. On factory-installed gateways, this cable is pre-attached to the MGMT port on CS 0 (Figure 44).

Note: You can also disconnect the pre-attached cable and directly connect a cable supplied by the customer.

EMC VNX VG2/VG8 Gateway Configuration Setup Guide

Figure 44 External network connection on Control Station

2. For dual Control Station systems, connect the cable from the MGMT port of CS 1 to the customer’s 10/100 Ethernet network. If possible, the two CSs should connect to different Ethernet switches in the customer’s network for high availability.

Note: For successful blade failover, you must establish identical network connections for the primary and standby blades.

4. Connect up to two optical Ethernet cables from ports on the I/O modules (Figure 45 on page 77) to the customer’s Gigabit Ethernet network.

Note: If the link light is off when the optical cables are connected, try swapping the receive and transmit connections. Some combinations of patch panels and multiple cables between the blade and the Ethernet switch can result in the connections being reversed.

5. If you are using the VNX VG2 gateway with a VNX array, ensure the Control Station external network is configured to have a network path to the VNX SPs. The network connectivity will be verified when you configure the Control Station.

Do not connect the VNX SPs to the management modules that connect the blades to the Control Station.

Note: The Control Station does not connect to a Symmetrix array through the Ethernet network. All Symmetrix management is done outside the Control Station.

6. Go to Chapter 8, “Configure the boot array.”

Connect Cables for a Fabric-connected VG8

Step 1: Blade Fibre Channel cables

The figures in this section of the document contain logical drawings of cable connections. To view the physical port locations, see “Identifying blades and I/O

modules” on page 40.

Fibre Channel cables connect the blades to the Symmetrix and VNX arrays through FC/FCoE switches. Each blade has two Fibre Channel ports that must be connected to both storage processors of the VNX array.

The Fibre Channel cables have not been connected.

The cabling and zoning rules for a VNX gateway system are minimum requirements. You can have additional paths between the array and the blades, but you must observe the following blade limits:

◆ 16 paths per LUN for Symmetrix storage arrays

◆ 8 paths per LUN for VNX storage arrays

◆ 4 paths per LUN is recommended for most configurations

Use the “FC/FCoE cabling worksheet” on page 273 to record the ports you actually cable.

Arrange the cables so that a failed component can be removed without disconnecting other cables.

Use small form-factor pluggable (SFP) modules in the SP and I/O module ports to connect the Fibre Channel cables (see “SFP modules” on page 43).

If you are using:

◆ Two switches, connect the cables as shown in Figure 55 on page 91.

◆ One switch, connect the cables as shown in Figure 56 on page 92.

The four-port Fibre Channel I/O module has two module types:

◆ 4 Gb/s supporting fibre speeds of 1, 2, or 4 Gb/s

◆ 8 Gb/s supporting fibre speeds of 2, 4, or 8 Gb/s

The two-port FCoE I/O module supports fibre speeds of up to 10 GB/s.

If the blades fail to boot from the array, you may have to manually force the Fibre Channel speed setting. If you must do this, set the switch ports to the highest speed (1 Gb, 2 Gb, 4 Gb, or 8 Gb) the switch can support. Appendix D, “Resolve Blade Boot

Failures,” provides more information.

Connect Cables for a Fabric-connected VG8

Connecting a Symmetrix array

For a Symmetrix array, you need two channel director ports dedicated to the VNX gateway system. These ports must be on different channel directors as shown in the examples in Figure 57 or Figure 58 on page 94.

Figure 57 Example of Symmetrix channel directors connected to two switches

Note: The Symmetrix DMX, VMAX, and VMAXe directors may have different numbers of ports than shown in Figure 57.

To make connections to two switches for high availability as illustrated in the example in Figure 57:

1. Verify the channel director ports to use from the CCA activity or the Symmetrix administrator for the VNX gateway system.

2. Connect the specified channel director port to the first switch.

3. Connect the specified port on another channel director to the second switch.

4. Record the channel director ports you connected to the switch ports by using the

“FC/FCoE cabling worksheet” on page 273.

Note: The Symmetrix VMAX and VMAXe channel directors have fewer ports than shown in

Figure 58.

To make connections to one switch as illustrated in the example in Figure 58:

1. Verify the channel director ports to use from the CCA activity or the Symmetrix administrator for the VNX gateway system.

2. Connect one specified channel director port to the switch.

3. Connect the specified port on another channel director to the switch.

4. Record the channel director ports you connected to the switch ports by using the

“FC/FCoE cabling worksheet” on page 273.

Connecting a VNX7500 array

Figure 59 VNX7500 connected to two switches for high availability (example)

The VNX7500 SP has 4 to 14 ports to connect to SAN fabrics. If all of the SAN ports on the array are already connected to the fabric, you need not change these connections. If the array has two available ports on each SP, the recommended practice is to cable these ports to the switches and dedicate them to the VNX gateway system.

If you are using two switches to connect a VNX7500 array, connect the cables as shown in the example in Figure 59.
