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.
