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 (

during which the configured disks are excluded from spin-down.
Configured Spin Down Delay
NOTE: The Configured Spin Down Delay option is not applicable for the No Power Savings mode.
The amount of time to wait before spinning down disks can be set using Configured Spin Down Delay. The minimum
value of the timer is 30 minutes (default) and the maximum is one day. Disks are spun down automatically and spun up
when accessed. All disks are spun up on reboot.
