Drive installation details for the 8001-12C system

Find information about the drive installation options for the IBM Power System S821LC (8001-12C)
system.
SATA Drives
The 8001-12C system can support four SATA drives 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. Up to two SATA
DOM drives can be installed. Use the two orange SATA connectors.
SAS Drives
With system feature codes EKB1 or EKB2, and by using SATA/SAS RAID adapters, the 8001-12C system
can support up to four SATA/SAS drives. Adapter feature codes EKAA and EKAB each support up to
eight SAS drives, but the system is physically limited to four.
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.
As an example, consider this configuration:
v Feature code EKAA supporting four front-mounted SATA/SAS drives.
v Two SATA DOMs plugged into the system backplane.
NVMe Enabled System and Drives
When the system has one or more NVMe adapters, feature code EKAE, the system supports NVMe
drives. To support up to two NVMe drives, you need a feature code EKAE PCIe adapter. To support up
to four NVMe drives, you need two EKAE PCIe adapters. Figure 88 shows the adapter positions. The
first EKAE PCIe adapter needs to go in position 2 (UIO Slot1); the second needs to go in position 3 (PLX
Slot1).
Figure 88. 8001-12C PCIe adapter positions
The first two NVMe drives need to be plugged into drive locations 1 and 2 as shown in Figure 89 on
page 88. The second two NVMe drives need to be plugged into drive locations 3 and 4.
