contiguous drive mapping (0 – 12), cable routing differs when using a x8 wide-port capable 6 Gb
SAS/SAS RAID Controller vs. using the embedded SCU ports.
5.5.1.1 Cable Routing using a x8 wide-port capable 6 Gb SAS/SAS RAID Controller
To ensure contiguous drive mapping when using a x8 wide-port capable 6 Gb SAS/SAS RAID
controller, the system must be cabled as follows:
 Cables from the SAS Expander to the hot swap backplane must be connected in order:
0 – 2.
 The cables from the SAS controller can be attached to any of the remaining connectors
on the SAS expander card.

5.5.1.2 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 12 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 – 12):
 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.
 Cables from the SAS Expander to the hot swap backplane must be connected in order:
Connector 1 – Connector 3.
 The SCU_0 or 3G SAS/SAS RAID (0-3) connector is cabled to the first mini-SAS
connector on the hot swap backplane
 The SCU_1 or 3G SAS/SAS RAID (4-7) connector is cable to Connector_0 on the SAS
expander card.
For storage configurations that require utilizing a hard disk drive as the boot device, the system
must be cabled as follows to ensure a boot device is found and contiguous drive mapping (0-
12).
 The SCU_0 (0-3) connector on the server board is cabled to the first mini-SAS connector
on the hot swap backplane
 The SCU_1 (4-7) connector on the server board is cable to Connector_0 on the SAS
expander card.
 Cables from the SAS Expander to the hot swap backplane must be connected in order:
Connector 1- Connector 3.
Note: Current SCU controller design limitations prevent any hard drive attached to a SAS
expander card from being a boot device when both SCU connectors are attached to the SAS
expander card.

5.5.2 24-Port and 36-Port Internal Intel RAID Expander Cards
For large storage configurations that utilize more than eight 2.5” hard disk drives, the system
may be configured with an internally mounted SAS expander card mounted directly behind the
drive bay assembly as shown in the following illustration. SAS expander selection is dependent
on the desired SAS controller configuration.
