HP SureStore E Disk Array XP512: Site Prep Guide

Uninterruptible Power Supply (UPS)

Most HP SureStore E Disk Array XP512 units are installed in data centers

where an uninterruptible power system (UPS) strategy is already in place.

However, if you are making your first large disk array purchase, you may

have a need for a separate UPS solution. HP references the Silcon DP300

series UPS solution. The Silcon DP300 is product from American Power

Conversion Corp (APC), manufacturers of uninterruptible power systems.

UPS Features

The APC UPS, Silcon DP300 series, provides the following feature set:

• Protection against short line transients

• Continued availability during short duration power failures (A

minimum of 30 minutes for a fully-configured system)

• Stable AC output voltage

• LCD display unit with ability to display key AC input/output

parameters, alarm log, events log and programming functions

• Communications Interface option for communicating a remote UPS

shutdown through the serial port connection.

UPS Limitations

While the UPS will provide uninterrupted power to the XP array in the

event of a power failure, once the battery runtime is exceeded, it will shut

down, resulting in a loss of AC power to the array. The UPS does have the

ability to communicate an oncoming shutdown to the host via the Silcon

Triple Chassis. The host can then pass this message in-band to the XP array

using the “xppf” program.
