IBM 5679 SAS RAID Enablement

The IBM 5679 is a SAS RAID enablement feature that adds RAID 0, 5, 6, and 10 capability with write cache to supported Power Systems servers.

Product Description

The IBM 5679 SAS RAID Enablement feature consists of two cards that must be installed together: the SAS RAID Enablement card and the SAS Auxiliary Cache card. The feature provides RAID 0, 5, 6, and 10 functions for internal SAS drives through a pluggable daughter card design. It includes 175 MB of write cache with battery backup. The auxiliary cache card supplies redundant write cache memory and the battery power pack. Concurrent maintenance of the RAID daughter card and auxiliary card is not supported, though concurrent maintenance of the battery pack is supported. A SAS DASD/Media Backplane is required.
