Appendix C RAID Controller Considerations
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.
