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.
Table 23. Mapping between backplane connectors and system board/adapter connectors when an SFF HBA/RAID
adapter is installed
Backplanes
Front BP (NVMe)
Front BP (SAS)
Rear BP (if any)
Notes:
• *NVMe 0-1 and NVMe 2-3 connectors are available only when the 4 x 3.5'' AnyBay front backplane is
used.
• Gen 3 and Gen 4 SFF HBA/RAID adapters are slightly different in their connectors, but the cable routing
method is similar.
The following figure illustrates the cable routing for the configuration of 4 x 3.5-inch front AnyBay drive bays
with an 8i SFF RAID adapter (Gen 4) and a rear 2 x 2.5-inch SAS/SATA drive cage. Connections between
