4 Power Requirements
This chapter describes the general power requirements for the HP 3PAR Storage systems.
Powering HP 3PAR Storage Systems
The cabinets used to house the HP 3PAR Storage system components are divided into power
domains where each contains a drive cage or controller node and two dedicated power supplies.
Drive cages and controller nodes depend on these two power supplies, located at the rear of the
system, to supply power from the Power Distribution Units (PDUs) that are located at the bottom of
the cabinet.
Figure 13 Power Supplies Within the Power Domains
HP cabinets contain four PDUs and each requires service from a dedicated single-phase 200-240
VAC (200-250 VAC International), 30-A (32-A International) grounded electrical circuit. However,
for optimal reliability and data accessibility, HP recommends a redundant AC configuration that
uses independent sources to provide a dedicated, grounded electrical circuit to each PDU as shown
in the following configuration:
