Server model with eight 2.5-inch SAS/SATA drives
Use this section to understand the connectors on the backplane and internal cable routing for server model with eight 2.5-inch SAS/SATA drives.
| 1 SAS 1 connector | 2 Power connector | 3 SAS 0 connector |
For power cable connection, see Power/Sideband cable routing.
Eight 2.5-inch SATA drives
| Cable | From | To |
|---|---|---|
| 1 SAS signal cable for front backplane | SAS 0 and SAS 1 connectors on the front backplane | PCIe connector 6 on the system board |
Eight 2.5-inch SAS/SATA drives and one 8i RAID/HBA adapter
RAID/HBA adapters can be installed in PCIe slot 1 or internal riser assembly.
When a Gen 4 RAID/HBA adapter is installed, ensure that you use the corresponding Gen 4 cable:
ThinkSystem SR635 2.5" SAS/SATA 8-Bay X40 RAID Cable Kit
| Cable | From | To |
|---|---|---|
| 1 SAS signal cable for front backplane | SAS 0 and SAS 1 connectors on the front backplane | The RAID/HBA adapter
|
Eight 2.5-inch SATA drives and rear SAS/SATA drive assembly
When the SAS/SATA backplanes are connected to PCIe connectors on the system board, only SATA drives are supported. No SAS drives are supported.
The cable routing illustration is based on the scenario that the rear hot-swap drive cage is installed. Depending on the model, the rear hot-swap drive cage might not be available on your server.
| Cable | From | To |
|---|---|---|
| 1 SAS signal cable for front backplane | SAS 0 and SAS 1 connectors on the front backplane | PCIe connector 6 on the system board |
| 2 SAS signal cable for rear backplane | SAS connector on the rear backplane | PCIe connector 7 on the system board |
Eight 2.5-inch SAS/SATA drives, rear SAS/SATA drive assembly and two 8i RAID/HBA adapters
When a Gen 4 RAID/HBA adapter is installed, ensure that you use the corresponding Gen 4 cable:
For cable 1: ThinkSystem SR635 2.5" SAS/SATA 8-Bay X40 RAID Cable Kit
For cable 2: ThinkSystem SR635 2.5” SAS/SATA 2-Bay Rear Backplane X40 RAID Cable Kit
| Cable | From | To |
|---|---|---|
| 1 SAS signal cable for front backplane | SAS 0 and SAS 1 connectors on the front backplane | The RAID/HBA adapter
|
| 2 SAS signal cable for rear backplane | SAS connector on the rear backplane | C0 connectors on the RAID/HBA adapter |
Eight 2.5-inch SAS/SATA drives, rear SAS/SATA drive assembly and one 16i RAID/HBA adapter
RAID/HBA adapters can be installed in PCIe slot 1 or internal riser assembly.
When a Gen 4 RAID/HBA adapter is installed, ensure that you use the corresponding Gen 4 cable:
For cable 1: ThinkSystem SR635 2.5" SAS/SATA 8-Bay X40 RAID Cable Kit
For cable 2: ThinkSystem SR635 2.5” SAS/SATA 2-Bay Rear Backplane X40 RAID Cable Kit
| Cable | From | To |
|---|---|---|
| 1 SAS signal cable for front backplane | SAS 0 and SAS 1 connectors on the front backplane | The RAID/HBA adapter
|
| 2 SAS signal cable for rear backplane | SAS connector on the rear backplane | The RAID/HBA adapter
|
Eight 2.5-inch SATA drives and rear NVMe drive assembly
When the SAS/SATA backplanes are connected to PCIe connectors on the system board, only SATA drives are supported. No SAS drives are supported.
The cable routing illustration is based on the scenario that the rear hot-swap drive cage is installed. Depending on the model, the rear hot-swap drive cage might not be available on your server.
| Cable | From | To |
|---|---|---|
| 1 SAS signal cable for front backplane | SAS 0 and SAS 1 connectors on the front backplane | PCIe connector 6 on the system board |
| 2 NVMe signal cable for rear backplane | NVMe connectors on the rear backplane | PCIe connector 1 on the system board |
Eight 2.5-inch SAS/SATA drives, rear NVMe drive assembly and one 8i RAID/HBA adapter
