Server model with 8 x 3.5-inch front drive bays (SAS/SATA)

This section provides cable routing information for the server model with one 8 x 3.5-inch SAS/SATA front backplane.

Configuration 1: one 8 x 3.5 SAS/SATA front backplane​

CableFromTo
1 SAS signal cableSAS 0 connector on the backplanePCIe connector 7 on the system board
2 SAS signal cableSAS 1 connector on the backplanePCIe connector 8 on the system board
Note

  • When the SAS/SATA backplane is connected to PCIe connectors on the system board, only SATA drives are supported. No SAS drives are supported.

  • When the SAS/SATA backplane is connected to PCIe connectors on the system board, x16/x16 riser card 3 is not supported.

Configuration 2: one 8 x 3.5 SAS/SATA front backplane, one 8i RAID/HBA adapter​

Note
The RAID/HBA adapter can be installed on the internal riser card (scenario 1), riser card 1 (scenario 2), or riser card 2 (scenario 3). The following illustration shows the cable connections for scenario 1. The cable connections are the same for scenarios 2 and 3.
