Figure 2.4 shows SAS connectors and SATA II connectors on SAS drives
and SATA II drives, respectively. Cables connect internal connectors on
the RAID controllers to connectors on SAS drives, SATA II drives, or
both. Both SAS drives and SATA II drives can connect to SAS backplane
receptable connectors. The difference between the SAS connector and
the SATA II connector is the bridge between the SAS primary physical
link and the power connector on the SAS controller, which the SATA II
connector does not have.
Note: SAS backplane connectors accept SAS drives or SATA II
drives, but SATA II backplane connectors cannot accept
SAS drives.
