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.
