Disk control frame
The DKC controls the disk array. It contains the control panel, connection hardware, power supplies,
SVP, and control boards for the disk array. It also contains up to 128 disk drives for the XP24000
and contains up to 120 disk drives for the XP20000.
DKC clusters
As the following figure shows, power and PCBs in the DKC are organized into two independent and
redundant clusters. Clustering helps ensure that if power or a PCB associated with one cluster stops
operating, the power and PCBs associated with the other cluster can continue to operate and support
the disk drives.
Cluster 1 consists of the assemblies at the front of the DKC.
Cluster 2 consists of the assemblies at the rear.
