23 12Gb/s Intel® RAID Controllers User Guide
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.
Figure 8. SAS Plugs, SATA Plugs, and SAS Backplane Receptacle Connector
The following subsection provides step-by-step instructions for connecting the 12Gb/s
Intel
®
RAID Controllers to SAS drives and SATA drives, either directly or through an
expander.
Connecting a RAID Controller with Internal Port Connectors
by Cable to Internal Drives
This section provides step-by-step instructions for connecting the SAS cable from the
internal SAS port connectors on the RAID controller to internal SAS drives and SATA
drives.
Follow these steps to connect your RAID controller with internal SAS port connectors
directly to SAS drives or SATA drives.
Note: The Intel
®
RAID Controller RS3DC080 is shown as an example. You can connect the
Intel
®
RAID Controller RS3DC040 in the same way.
