Figure 42. Internal 36-Port SAS Expander Card
Figure 43. 36-Port Expander SAS Connector/Drive Identification Block Diagram
Each connector on the SAS expander card can be used as a “cable in” (SAS Controller to SAS
Expander) or “cable out” (SAS Expander to Hot Swap Backplane) type connector. However, for
contiguous drive mapping (0 – 16 or 0 – 24), cable routing differs when using a x8 wide-port
capable 6 Gb SAS/SAS RAID Controller vs. using the embedded SCU ports.
5.5.2.1 Cable Routing using a x8 wide-port capable 6 Gb SAS/SAS RAID Controller
To ensure contiguous drive mapping when using x8 wide-port capable 6 Gb SAS/SAS RAID
Controller with a SAS expander card, the system must be cabled as follows:
 Cables from the SAS Expander to the hot swap backplane must be connected in order:
A – D for 16-drive configurations, and A – F for 24 drive configurations.
 The cables from the SAS controller can be attached to any of the remaining connectors
on the SAS expander card.
5.5.2.2 Cable Routing using the embedded SCU ports
Note: The following may also be applied when using any 3 Gb SAS/SAS RAID Controller.
For storage configurations that utilize up to 16 or 24 hard disk drives for storage only and an
internally mounted SSD as a boot device, the system must be configured as follows to
ensure contiguous drive mapping (0 – 16 or 0-24):
 At least one internally mounted SSD device must be attached to the AHCI controller
(SATA_0 or SATA_1 on the server board) and used as a boot device.
