Managing The Physical Disk Power
Does my controller support this feature? See Supported Features.
The Manage Physical Disk Power task allows you to manage the power consumed by the physical disks.
NOTE
: The Manage Physical Disk Power task is provided with H330 cards by spinning down the hot spares and uncongured
disks. PERC H730P, H730, H740P, and H840 cards also support the Manage Physical Disk Power task with additional power-
saving modes, Spin Down Congured Drives, and Automatic Disk Power Saving (Idle C) options.

You can enable one of the following modes to manage the power consumed:
