on a backplane. A SATA II connector consists of a signal connector and
a power connector.
Figure 2.3 SATA II Connectors
Figure 2.4 shows SAS and SATA II connectors on SAS and SATA II
physical disks, respectively. Cables are used for connection between
internal connectors on the RAID controller and connectors on SAS
and/or SATA II drives, respectively. Both SAS and SATA II physical disks
can connect to SAS backplane receptable connectors. The difference
between the SAS connector and SATA II connector is the bridge between
the SAS primary physical link and power connector on the SAS
controller, which the SATA II connector does not have.
Note:
SAS backplane connectors can accept SAS or SATA II
physical disks, but SATA II backplane connectors
cannot
accept SAS drives.
