EMC CONFIDENTIAL
WARNING
In case of fire or other emergency involving the EMC product, isolate the product’s
power and alert appropriate personnel.
CAUTION
!
Trained personnel are advised to exercise great care at all times when working on
EMC hardware.
Remember to:
◆Remove rings, watches, or other jewelry and neckties before you begin any procedures.
◆Use caution near any moving part and any part that may start unexpectedly such as fans,
motors, solenoids, etc.
◆Always use the correct tools for the job.
◆Always use the correct replacement parts.
◆Keep all paperwork, including incident reports, up to date, complete, and accurate.
Static precautions EMC incorporates state-of-the-art technology in its designs, including the use of LSI
and VLSI components. These chips are very susceptible to damage caused by static
discharge and need to be handled accordingly.
CAUTION
!
Before handling printed circuit boards or other parts containing LSI and/or VLSI
components, observe the following precautions:
◆Store all printed circuit boards in antistatic bags.
◆Use a ground strap whenever you handle a printed circuit board.
◆Unless specifically designed for nondisruptive replacement, never plug or unplug
printed circuit boards with the power on. Severe component damage may result.

EMC VNX VG2/VG8 Gateway Configuration Setup Guide

Introduction
EMC CONFIDENTIAL
Product introduction
The EMC®VNX VG2/VG8 servers are network-attached storage (NAS) gateways
that connect to EMC Symmetrix®(DMX™, VMAX™, or VMAXe™) or VNX storage
arrays or both.
IMPORTANT
!
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.
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 (SRDF®), are supported only when the VNX gateway boots from the
