2 x SAS/SATA backplanes

Follow the instructions in this section to learn how to do cable routing for two SAS/SATA backplanes.

Note

For more information about the power cable routing, see 2.5-inch drive backplane cable routing (server model with three 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:
- HL PCIe riser 1 and 3:
  - 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 (940-32i, 940-16i, 540-16i, 440-16i, 940-8i, 540-8i, 440-8i): SlimSAS x8 to SlimSAS x8 cable
- FL PCIe riser 1 and 3:
  - Gen4 RAID/HBA adapters (940-32i, 940-16i, 540-16i, 440-16i, 940-8i, 540-8i, 440-8i): SlimSAS x8 to SlimSAS x8 cable
- HL PCIe riser 2:
  - 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

This configuration contains the following storage controller combinations:

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.

Table 1. SAS/SATA cable routing
SAS/SATA cable routing to PCIe riser 1	SAS/SATA cable routing to PCIe riser 2

SAS/SATA cable routing to PCIe riser 3

Cable	From	To
`1`	Backplane 1: SAS/SATA	16i adapter: Gen4: C0 Gen3: C0, C1
`2`	Backplane 2: SAS/SATA	16i adapter: Gen4: C1 Gen3: C2, C3

Based on the location of the RAID adapter, select the corresponding routing path for SAS/SATA cable from the following table.

Table 2. SAS/SATA cable routing
SAS/SATA cable routing to PCIe riser 1	SAS/SATA cable routing to PCIe riser 3

Cable	From	To
`1`	Backplane 1: SAS/SATA	32i adapter: C0
`2`	Backplane 2: SAS/SATA	32i adapter: C1
