Replacing the p1224 RAID controller and
components
RAID controller component overview
All HPE StoreOnce Systems described within this guide use the p1224 RAID controller fitted with a RAID
cache module and SuperCapacitor. Each model has a single RAID controller.
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).
HPE StoreOnce 3500 Series and HPE StoreOnce 5100 System also have a SAS Expander card.
NOTE:
The locations of RAID cards and the internal SAS cabling configuration are also shown on the
StoreOnce hood label inside the server.
