5 The HP p1224 RAID controller

HP p1224 controller in StoreOnce systems

All HPE StoreOnce Backup systems described in this guide use the HP p1224 RAID controller
fitted with a RAID cache module and SuperCapacitor.
The HPE StoreOnce 4700 Backup has two RAID controllers; the HPE 2700, 2900 and 4500
Backup have one RAID controller.
There are two cables that may need replacement.
An internal cable connects the internal SAS port on the RAID controller to the SAS storage
in the server unit
An external cable connects the external SAS port on the controller to the SAS storage in
the expansion shelf
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).
