The p1228 RAID card in a StoreOnce 4900 server

The HPE StoreOnce 4900 Backup system uses the HP p1228 RAID controller fitted with a RAID
cache module and SuperCapacitor. The HPE StoreOnce 4900 Backup has two RAID controllers.
Cables connect the external SAS ports on the controller to the SAS storage in the disk
enclosure(s). The RAID cache module is seated on the RAID card and has one port to connect
to the SuperCapacitor (which is located in the center of the unit, clipped to the floor of the chassis
behind the disk cage).
