IBM Storwize V5030 User Manual

680 Implementing the IBM Storwize V5000 Gen2 with IBM Spectrum Virtualize V8.1
12.2.5 Power supply units
All enclosures require two power supply units (PSUs) for normal operation. A single PSU can
power the entire enclosure for redundancy. We advise that you supply AC power to each PSU
from different power distribution units (PDUs).
Figure 12-22 shows a fully equipped control enclosure with two supply units. The PSUs are
identical between the control and expansion enclosures.
Figure 12-22 Power supply units
The left PSU is numbered 1, and the right PSU is numbered 2.
Power supplies in both control and expansion enclosures are hot-swappable and replaceable
without a need to shut down a node or cluster. If the power is interrupted in one node canister
for less than 2.5 seconds, the canister cannot perform a fire hose dump and continues
operation from battery.
