4 x 2.5'' SAS/SATA backplane
Use this section to understand the SAS/SATA backplane cable routing for server model with four 2.5'' front drives.
To connect power cables for a backplane for standard 2.5'' or 3.5'' drives, refer to Backplane power cable routing.
To connector cables of RAID flash power modules, refer to RAID flash power modules.
To connect signal cables for a backplane for standard 4 x 2.5'' front drives, refer to the following cable routing scenarios depending on your server configuration:
Cable routing for onboard configuration
The following table shows the mapping relationship between backplane connectors and system board connectors for onboard configuration.
Figure 1. Cable routing for onboard configuration of 4 x 2.5'' front SAS/SATA drive bays
| Backplanes | From | To |
|---|---|---|
| Front BP (SAS) | SAS | PCIe connector 7 |
Cable routing with an SFF HBA/RAID adapter
The following table shows the mapping relationship between backplane connectors and system board/adapter connectors when an 8i SFF HBA/RAID adapter (Gen 3 or Gen 4) is installed.
Figure 2. Cable routing for 4 x 2.5'' front AnyBay drive bays with an 8i SFF RAID adapter (Gen 3 or Gen 4)
| Backplanes | From | To |
|---|---|---|
| Front BP (SAS) | 1 SAS | 1 C0 |
Note
Gen 3 and Gen 4 SFF HBA/RAID adapters are slightly different in their connectors, but the cable routing method is similar.
