Managing Spare Drives

Managing Spare Drives

After RAID configuration of the hard drives of a server, configuration of hot spare drives increases security and reduces impact on services from hard drive faults.

The controller card supports two types of hot spare drives:

  • Global hot spare drive: shared by all RAID arrays of a controller, which can be configured with one or more global hot spare drives. A global hot spare drive automatically replaces a failed hard drive of the same type as the hot spare drive in any RAID array.
  • Dedicated hot spare drive: replaces a failed hard drive of the same type as the hot spare drive only in a specified RAID array, which can be configured with one or more dedicated hot spare drives.
  • An idle hard drive can be configured as a hot spare drive, but a RAID member drive cannot be configured as a hot spare drive.
  • A hot spare drive must be a SATA or SAS drive, and it must have at least the capacity of the RAID member drive with the largest capacity.
  • All RAID levels except RAID 0 support hot spare drives.
