Connecting the Cables
This section describes the cables used on the SAS controller and provides instructions for
connecting SAS and SATA hard disk drives to the SAS RAID controller.
Note: Use only “straight” SAS cables, not “cross-over” SAS cables.
A SATA connector consists of a signal connector and a power connector. The SAS
connector adds a bridge (primary physical link) between the signal connector and the
power connector. This means SAS backplane connectors can accept either drive type, but
SATA backplane connectors can ONLY accept SATA drives. Figure 3 shows these
connectors.
