Storage Controller and Backplane Connectors
This section describes cabling connections for the storage controllers and the backplane. The SAS/SATA
cables are factory-installed and are used for all supported internal controllers in the SFF 10-drive of the
SE-CL-L3 .
This section also contains diagrams that show the cable-to-drive mapping.
Embedded RAID
This SW RAID option can control up to 8 SATA drives in the SFF 10-drive version and up to 4 SATA drives
in the LFF 4-drive version.
This embedded RAID option requires that you have a SATA interposer card installed in internal mRAID riser
3. Use the SAS/SATA cables that came with the server.
1. Connect SAS/SATA cable A1 from the A1 interposer connector to the A1 backplane connector.
2. Connect SAS/SATA cable A2 from the A2 interposer connector to the A2 backplane connector.
See the following figures that illustrate cable connections and which drives are controlled by each cable. In
the SFF 10-drive version, drives 5 and 10 cannot be controlled by the embedded SATA RAID controller.
