About This Task - IBM Storwize V7000 Unified Manual

modules or the control enclosure to receive a signal that the UPS input power has
been interrupted, or that it is about to stop suppling power from its batteries.
File system corruption is still possible when the power is removed from the file
modules without being properly shutdown first. The control enclosure has its own
batteries to allow critical system state and cached writes to volumes to be saved
after its power supply is interrupted.
If an UPS is used then it is best if the file modules, storage enclosures, and
Ethernet switches in the rack are all connected to the same UPS. The bottom of the
rack is the best location for the UPS.
Storwize V7000 Unified physical installation planning
Before you set up your Storwize V7000 Unified environment, verify that the
prerequisite conditions are met.

About this task

This information applies to the supported hardware components.
Procedure
1. Does your physical site meet the environment requirements for Storwize V7000
2. Do you have adequate rack space for your hardware?
3. Do the power circuits that you are planning to use have sufficient capacity and
4. Have you provided appropriate connectivity by preparing your environment?
Storwize V7000 Unified operating environment
To use the system, you must meet the minimum hardware and software
requirements and ensure that other operating environment criteria are met.
Minimum requirements
You must set up your Storwize V7000 Unified operating environment with a
minimum of one control enclosure and one pair of Storwize V7000 Unified file
modules. The file modules are connected only to the control enclosure that
provides I/O group 0. Even in a system with four control enclosures, there is only
one pair of Storwize V7000 Unified file modules.

Unified?
The Storwize V7000 Unified requires two Electronic Industries Alliance (EIA)
units for each control enclosure or expansion enclosure.
the correct sockets for your Storwize V7000 Unified installation?
v A clearly visible and accessible emergency power off switch is required.
v For redundancy, two independent power circuits are required. One circuit
connects to each power supply in each enclosure.
v If you are using the redundant ac-power switch, the redundant ac-power
switch main input and the other circuit connect to the redundant ac-power
switch backup input.
