RAID Controller Cabling
Cisco UCS C22 Server Cabling
Small Form Factor 8-Drive Backplane Cabling
The cable connections required for each type of controller are as follows:
Embedded RAID
This option can control up to eight internal drives.
The required UCSC-CABLE-AE cable kit has two mini-SAS cables. Cable 1 controls drives 1–4 and
cable 2 controls drives 5–8.
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.
Step 3 Connect mini-SAS cable 2 from the motherboard connector SCU_Port_1 to the drives 5–8 connectors
on the backplane.
Step 4 Connect the cable 2 SGPIO connector labeled, “S2” to backplane connector B.
LSI MegaRAID 9220-4i PCIe Card
This option can control up to four internal drives.
The required UCSC-CABLE-A2 cable kit has two mini-SAS cables. Cable 1 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 eight internal drives.
The required UCSC-CABLE-A2 cable kit has two mini-SAS cables. Cable 1 controls drives 1–4 and
cable 2 controls drives 5–8.
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.
Step 3 Connect mini-SAS cable 2 from connector SAS2 on the card to the drives 5–8 connectors on the
backplane.
Step 4 Connect the mini-SAS cable 2 SGPIO connector S2 to backplane connector B.
