2.4SAS Device Cables

This section describes the cables used on the RAID controller and provides step-by-step instructions for connecting SAS and/or SATA II physical disks to the controller. The SAS and SATA II protocols use a thin, 7-wire connector instead of the 68-wire SCSI cable or 26-wire ATA cable.

Note: Use only straight SAS cables, not cross-over SAS cables.

Figure 2.2 displays the SAS cable that connects the internal connectors on a RAID controller to SAS drives.
