NOTE: The Manage Physical Disk Power task is provided with PERC H700, H800, H310 and H330
cards by spinning down the hot spares and unconfigured disks. PERC H710, H710P, H810, H730P,
H730, and H830 cards also support the Manage Physical Disk Power task with additional power-
saving modes, Spin Down Configured 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 configured drives by
setting the Start Time and Time interval to spin up.
To enable the Quality of Service (QoS) feature:
1. Select Customized Power Savings Mode.
2. Select Enable for the Spin Down Configured Drives option
