Cabling the SAS RAID Controller
For a system with the optional SAS RAID controller daughter card installed, you can configure your
system to use the 1x8 SAS backplane only or the 1x8 SAS backplane with the optional 1x2 SAS
backplane installed. Cabling for each configuration is discussed in the following subsections. See your
SAS RAID controller documentation for details on the different RAID levels supported for your
configuration and the drive requirements for specific RAID types.
1x8 Drive Configuration
For a 1x8 drive configuration with no optional 1x2 backplane installed in the system, connect SAS_0 on
the SAS controller daughter card to connector SAS_A on the 1x8 backplane. Connect SAS_1 on the SAS
controller daughter card to connector SAS_B on the 1x8 backplane. See Figure 3-30.
