Chapter 2: Power requirements

To assure predictable and reliable performance of the storage system in the data center,
observe the appropriate power requirements.

Power cable usage guidelines

Hitachi storage systems are intended for rack installation and ship with power cords.
Installation and service requirements may require additional cords and cables to be
ordered. The type of power cable required by a given installation is determined primarily
by the:
Type of AC line feed provided by the facility.
■
Type of AC source (wall outlet or modular and monitored PDU) to be used.
■
Serviceability of components to be connected.
■
Storage systems require a country-specific power cable for direct connection to a facility
AC feed.
Storage systems are designed to allow replacement of hot-pluggable components
without removing the chassis from the rack. As a result, power cables can be short
because cable movement is of minimal consideration.

Electrical requirements

The storage system requires two easily accessible power outlets near the rear of each
controller. Each drive tray requires an additional power outlet.
The storage system controller and drive trays are equipped with two fully redundant
wide-ranging power supplies that automatically accommodate voltages to the AC power
source. The power supplies operate within the range of the storage system model:
VSP F350 and 370 or G350 and G370: single phase 100-120 VAC or 200-240 VAC
■
VSP F700 or F900 and G700 or G900: single phase 200-240 VAC
■
The power supplies meet standard voltage requirements for both domestic (inside USA)
and international (outside USA) operation. When connecting to an AC source, be sure the
current does not exceed the rating of the power source circuitry. This includes cabling,
power distribution units, filters, and any other components through which the main AC
flows.
