Hard Drive Hot Spares

Hard Drive Hot Spares

A hot spare drive replaces a failed drive in a RAID array and stores the data of the failed drive.

The LSI SAS2308 supports a maximum of two global hot spare drives. If one or two member drives of the same type as hot spare drives fail, hot spare drives take over data processing to prevent data loss or fault deterioration.

LSI SAS2308 does not support emergency spares and dedicated hot spare drives.

For details about how to configure hot spare drives, see Configuring a Hot Spare Drive.

The HDDs and SSDs cannot be used as the hot spare drives of each other.
