Figure 8. Up to eight SAS or SATA drives, or a mix of SAS HDDs and SATA SSDs (eight drives total), SAS/
SATA adapter, four NVMe drives attached to an NVMe adapter, and up to two DOMs
SATA Drives
The 9006-22C system with direct attach drive backplane can support up to 12 SATA drives. The drives are
directly connected to the SATA ports and to the 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.
You can plug SATA drive on module (DOM) drives directly into the system backplane. Use the two orange
SATA connectors. You can use up to two SATA DOM drives.
Figure 9 on page 12 shows the port to drive bay mapping for the disk drive backplane.
A
Maps to mini-SAS drive connector 1 and supports the indicated drive bays 0 through 3.
B
Maps to mini-SAS drive connector 2 and supports the indicated drive bays 0 through 3.
C
Maps to mini-SAS drive connector 3 and supports the indicated drive bays 0 through 3.

SAS Drives
With the direct attach drive backplane and by using the system backplane controllers, the system can
support up to eight SATA/SAS drives with a maximum of four SATA drives. There are two SAS cables that
connect the disk drive backplane to the system backplane.
With the direct attach drive backplane and by using SAS/SATA RAID adapters, the system can support up
to twelve front SATA/SAS drives. If you are installing a RAID adapter, use three SAS cables to connect the
SAS ports on the PCIe adapter card to the SAS ports on the disk drive backplane.
