Server models with eight 2.5-inch drives

Use this section to understand the cable routing for server models with eight 2.5-inch drives.

Server model: eight 2.5-inch SAS/SATA drives, one 8i RAID/HBA adapter​

Note
The following illustration is based on the scenario that the RAID/HBA adapter is installed in PCIe slot 4 on the system board. If there is a serial port module installed in PCIe slot 4, the RAID/HBA adapter will be installed in PCIe slot 1 on riser 1. In both scenarios, the cable connections are the same.

CableFromTo
1 Power cablePower connector on the backplaneBackplane power connector 1 on the system board
2 SAS signal cable*SAS 0 and SAS 1 connectors on the backplane
HBA/RAID adapter:

  • Gen 3: C0C1

  • Gen 4: C0

Note
*When Gen 4 HBA/RAID adapter is installed, ensure you use Gen 4 SAS signal cable (ThinkSystem SR550/SR590/SR650 2.5" SAS/SATA/AnyBay 8-Bay X40 RAID Cable Kit).

Server model: four 2.5-inch SAS/SATA drives, four 2.5-inch SAS/SATA/NVMe drives, one 8i RAID/HBA adapter​

Note

The following illustration is based on the scenario that the RAID/HBA adapter is installed in PCIe slot 4 on the system board. If there is a serial port module installed in PCIe slot 4, the RAID/HBA adapter will be installed in PCIe slot 1 on riser 1. In both scenarios, the cable connections are the same.
