Drive installation options for the 9006-12P system
Find information about the drive installation options for the IBM Power System LC921 (9006-12P)
system.
SATA Drives
The system can support four SATA drives. The SATA drives can be installed into the front drive bay
locations.
One SAS cable connects the disk drive backplane to 4 SATA sockets on the system backplane.
You can plug SATA drive on module (DOM) drives directly into the system backplane. Up to two SATA
DOM drives can be installed. Use the two orange SATA connectors.
SAS Drives
By using SATA/SAS RAID adapters, the system can support up to four SATA/SAS drives.
One SAS cable connects the SAS port on the disk drive backplane to the SAS port on the system
backplane.
Sample SAS configuration:
• RAID adapter supporting four front-mounted SATA/SAS drives.
• Two SATA DOMs plugged into the system backplane.
NVMe Enabled System and Drives
When the system has an NVMe adapter, the system supports NVMe drives. The first two NVMe drives
must be plugged into drive locations 1 and 2 as shown in Figure 83 on page 105. The second two NVMe
drives must be plugged into drive locations 3 and 4.
Two NVMe cables connect the disk drive backplane to the NVMe storage adapter.
NVMe drives are supported only on host operating systems. NVMe drives are not supported by guest
operating systems. On systems with RHEL 7.3 or later, or Ubuntu 16.04 or later, NVMe drives can be used
as bootable drives. Port 1 of the internal NVMe host bus adapter must be plugged into NVMe port 1 on the
disk drive backplane.
Figure 83. NVMe drive locations
Sample NVMe configuration:
• Four NVMe front-mounted drives with the NVMe adapter.
• Two SATA DOMs plugged into the system backplane.
