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 or 16i SFF HBA/RAID adapter (Gen 3 or Gen 4) is installed.

adapter is installed

Front BP (NVMe)
Front BP (SAS)
Rear BP (if any)
Notes:
• *NVMe 4-5, NVMe 6-7, and NVMe 8-9 connectors are available only when the 10 x 2.5'' AnyBay front
backplane is used.
• *The SAS 2 connector only needs to be connected in the front drive scenario of 10 x 2.5'' AnyBay or 6 x
2.5'' SAS/SATA + 4 x 2.5'' AnyBay.
• 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 10 x 2.5-inch front AnyBay drive bays
with a 16i SFF RAID adapter (Gen 4) and a rear 2 x 2.5-inch SAS/SATA drive cage. Connections between
