Hard Drive Hot Spares

Hard Drive Hot Spares

Hot spare drives are used to replace member drives in an array and take over data on faulty member drives.

The PM8060 supports a maximum of two hot spare drives. When one or two member drives of the same type as hot spare drives fail, they are replaced by hot spare drives to prevent data loss or fault deterioration.

  • The HDDs and SSDs cannot be used as the hot spare drives of each other.
  • The HDDs include SAS HDDs and SATA HDDS. If the member drives of a RAID array are SAS drives, the SATA drives can be used as dedicated hot spare drives. If the member drives are SATA drives, the SAS drives cannot be used as dedicated hot spare drives.
