Physical disk power management

Physical disk power management is a power-saving feature of the Shared PERC 8 card. Idle-C feature, as defined by the T10 organization, is autoenabled for physical disk power management. Physical disks that support Idle-C feature, spin at lower RPMs upon timer expiration when there is no I/O activity.
  • NOTE: There is a delay to I/O operations when a configured disk is being spun up.
  • NOTE: For detailed information about power management, see the Dell Chassis Management Controller for Dell PowerEdge VRTX User’s Guide at Dell.com/poweredgemanuals.
