A new type of RAID has been introduced in SVC v7.6 - Distributed RAID (DRAID).

While traditional RAID arrays have one or more dedicated spare drives which are idle unless an active member in the array fails, DRAID arrays have so called rebuild areas which means there is no dedicated spare drive and all drives in the array can do I/O.

DRAIDs have two major advantages over traditional RAID arrays: greater throughput and a massively reduced rebuild time in case of a drive failure.

 

There are a bunch of new attributes related to DRAID which can now be displayed in the Detail Pane for Object Type "Drive Array".
