  • Drive states

  • Solid State Disks (SSDs)
    Solid-state disks (SSDs) are data storage devices that use solid state memory (flash) to store data persistently. SSDs emulate conventional hard drives, and are available with the same interfaces that hard drives use.
  • Hot spare drives
    Hot spares act as standby drives in RAID 1, RAID 5, or RAID 6 volume groups for System Manager . They are fully functional drives that contain no data. If a drive fails in the volume group, the controller automatically reconstructs data from the failed drive to a drive assigned as a hot spare.
