Note: Use only straight SAS cables, not crossover SAS cables.
The following figure shows the SAS cable that connects the internal connectors on a SAS
RAID controller to SAS drives, SATA drives, or both.
Figure 4. Internal SAS Cable for Connection to SAS Drives, SATA II Drives,
or SATA III Drives
The following figure shows the SATA III device plug connector that connects a SAS
RAID controller with internal connectors to the host receptacle connector on a backplane.
A SATA III connector consists of a signal connector and a power connector.
Figure 5. SATA III Connectors
The following figure shows SAS connectors and SATA connectors on SAS drives and
SATA drives, respectively. Cables connect internal connectors on the RAID controllers to
connectors on SAS drives, SATA drives, or both. Both SAS drives and SATA drives can
connect to SAS backplane receptacle connectors. The difference between the SAS
connector and the SATA connector is the bridge between the SAS primary physical link
and the power connector on the SAS controller, which the SATA connector does not have.
