RAID Controller Cabling

Large Form Factor 4-Drive Backplane Cabling

The cable connections required for each type of controller are as follows:

•Embedded RAID, page C-21

•LSI MegaRAID 9220-4i PCIe Card, page C-21

•LSI MegaRAID 9220-8i,9240-8i, or 9265CV-8i PCIe Card, page C-21

Embedded RAID

This option can control up to four internal drives.

The required UCSC-CABLE-A9 cable kit has one mini-SAS cable that controls drives 1–4.

Step 1 Connect mini-SAS cable 1 from the motherboard connector SCU_Port_0 to the drives 1–4 connectors on the backplane (see Figure C-2).

Step 2 Connect the cable 1 SGPIO connector labeled, “S1” to backplane connector A.

LSI MegaRAID 9220-4i PCIe Card

This option can control up to four internal drives.

The required UCSC-CABLE-A10 cable kit has one mini-SAS cable that controls drives 1–4.

Step 1 Connect mini-SAS cable 1 from connector SAS1 on the card to the drives 1–4 connectors on the backplane.

Step 2 Connect the mini-SAS cable 1 SGPIO connector S1 to backplane connector A.

LSI MegaRAID 9220-8i, 9240-8i, or 9265CV-8i PCIe Card

These options can control up to four internal drives.

The required UCSC-CABLE-A10 cable kit has one mini-SAS cable that controls drives 1–4.

Step 1 Connect mini-SAS cable 1 from connector SAS1 on the card to the drives 1–4 connectors on the backplane.

Step 2 Connect the mini-SAS cable 1 SGPIO connector S1 to backplane connector A.
