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.
NOTE: This task is not supported on PERC hardware controllers running in HBA mode.
You can enable one of the following modes to manage the power consumed:
• No Power Savings Mode — This is the default mode for the controller. In this mode, all power-saving features are disabled.
• Balanced Power Savings Mode — Provides good power savings while limiting I/O latency.
• Maximum Power Savings Mode — Provides maximum power savings for all drives.
• Customized Power Savings Mode — Allows you to customize the power-saving settings. The default values are populated when you
select this power mode. You can select or clear the features you want to enable. You can select Quality of Service (QoS) to customize
power saving on congured drives by setting the Start Time and Time interval to spin up.
