3 x SAS/SATA backplanes
Follow the instructions in this section to learn how to do cable routing for three SAS/SATA backplanes.
Note
- For more information about the power cable routing, see 2.5-inch drive backplane cable routing (server model with four PCIe risers).
- When routing the cables, ensure that all cables are routed appropriately through the cable guides and cable clips.
- Make sure to choose the cables based on the generation of RAID adapters that you plan to install:
- Gen3 RAID/HBA adapters (9350-16i, 4350-16i, 9350-8i, 5350-8i, 4350-8i): Mini-SAS x4*2 to SlimSAS x8 cable
- Gen4 RAID/HBA adapters (940-16i, 540-16i, 440-16i, 940-8i, 540-8i, 440-8i): SlimSAS x8 to SlimSAS x8 cable
8i + 16i RAID/HBA adapter
Based on the location of the RAID/HBA adapter, select the corresponding routing path for SAS/SATA cable from the following table.
| SAS/SATA cable routing to PCIe riser A | SAS/SATA cable routing to PCIe riser B |
|---|---|
 |  |
| SAS/SATA cable routing to PCIe riser C | SAS/SATA cable routing to PCIe riser D |
 |  |
| Cable | From | To |
|---|---|---|
| 1 | Backplane 1: SAS/SATA | 16i adapter
|
| 2 | Backplane 2: SAS/SATA | 16i adapter
|
| 3 | Backplane 3: SAS/SATA | 8i adapter
