Dell PowerEdge RAID Controller 9 User’s Guide H330, H730, and H830

Physical disk power management is a power-saving feature of the PERC 9 series 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 or Unified Extensible Firmware Interface (UEFI) RAID Configuration utility. For more information, see the Dell OpenManage documentation at Dell.com/openmanagemanuals.

There are four power-saving modes:

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.

NOTE: The maximum power savings mode is not supported by the H330 PERC card.

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.

NOTE: The customized power savings mode is not supported by the H330 PERC card.
