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.
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.
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.
