Idle Power Management Scope
Storport Idle Power Management (IPM) provides idle power management for the LUN, not the adapter. Storport IPM does not attempt to place the adapter in a low power state if all its LUNs are in a low power state. The miniport driver is responsible for managing adapter power.
Storport IPM is supported in the following system configuration only:
- Systems that use a SATA adapter with a single SATA disk drive attached
Storport IPM is not supported in the following system configurations:
Systems that have non-direct attached storage (FC, iSCSI, and others)
Systems that have external storage arrays and RAID controllers
Systems that have MPIO
Systems that have non-SATA host bus adapters
Systems that have more than one disk attached to a SATA adapter
