Intel® RAID Controller SRCSAS18E User’s Guide 14
Figure 5 show SAS and SATA connectors on SAS and SATA hard disk drives,
respectively. Cables are used for connection between internal connectors on the RAID
controller and connectors on SAS and SATA drives, respectively. Both SAS and SATA
hard disk drives can connect to SAS backplane receptable connectors. The difference
between the SAS connector and SATA connector is the bridge between the SAS primary
physical link and power connector on the SAS controller.
Note: SAS backplane connectors can accept SAS or SATA hard disk drives, but SATA backplane
connectors cannot accept SAS drives.
