Physical Disk Power Management
Physical disk power management is a power saving feature of the PERC H310, H710, H710P, and H810 cards. The feature
allows disks to be spun down based on disk configuration and I/O activity. The feature is supported on all rotating SAS
and SATA disks and includes unconfigured, configured and  hot-spare disks. The physical disk power management
feature is disabled by default. The feature can be enabled in the Dell Open Manage Storage Management application
using the Unified Extensible Firmware Interface (UEFI) RAID Configuration utility. For more information, see the Dell
OpenManage documentation at dell.com/support/manuals.
There are four power saving modes available:
No Power
Savings (default
mode)
All power savings features are disabled.
Balanced Power
Savings
Spin down is enabled only for unconfigured and hot spare disks.
Maximum Power
Savings
Spin down is enabled for configured, unconfigured and hot spare disks.
Customized
Power Savings
All power savings features are customizable. You can specify a Quality of Service window
during which the configured disks are excluded from spin-down.
