SAS Device Cables and Connectors

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.

NOTE SAS backplane connectors accept SAS drives or SATA drives, but SATA backplane connectors cannot

accept SAS drives.
