SATA Drives
The 8001-22C system with feature codes EKB1 or EKB5 can support up to eight SATA drives. The drives
supported drops to six if the system has a GPU. The drives are directly connected to the SATA ports and
controller on the system backplane. The SATA drives can be installed into the front drive bay locations.
SATA drive cables connect the disk drive backplane to the SATA sockets on the system backplane.
Use SATA cables to connect the SATA ports on the system backplane to the SATA ports on the disk drive
backplane.
You can plug SATA drive on module (DOM) drives directly into the system backplane. Use the two
orange SATA connectors. If you use SATA DOM, they limit the number of front-mounted SATA drives.
You can use up to two SATA DOM drives.
v If you have one SATA DOM plugged into the system backplane, you can use up to seven
front-mounted SATA drives.
v If you have two SATA DOMs plugged into the system backplane, you can use up to six front-mounted
SATA drives.
By adding a storage adapter, feature code EKEA or EKEB, you can have up to twelve front-mounted
SATA drives. Drive cables connect to the storage adapter to eight of the front drives, and to the SATA
connectors on the system backplane for the remaining four drives. Figure 3 shows the port to drive bay
mapping for the disk drive backplane.
A: dotted area
Maps to mini-SAS drive connector 1 and supports the indicated drive bays 0 through 3.
B: dots and dashes area
Maps to mini-SAS drive connector 2 and supports the indicated drive bays 0 through 3.
C: dashes area
Maps to mini-SAS drive connector 3 and supports the indicated drive bays 0 through 3.

SAS Drives
With system feature codes EKB1 or EKB5, and by using a SATA/SAS RAID adapter, the 8001-22C system
can support up to eight SATA/SAS drives and four SATA drives. The drives supported drops to eight if
the system has a GPU, and if two of the drives are SATA only. Adapter feature codes EKEA and EKEB
each support up to eight SATA/SAS drives.
Use SAS cables to connect the SAS ports on the PCIe adapter cards to the SAS ports on the disk drive
backplane.
If you are installing a RAID adapter, see the adapter documentation for information on configuring the
drives.
