One 8 x SAS/SATA and two 8 x NVMe (Gen 4) backplanes

This section provides cable routing information for the server model with one 8 x 2.5" SAS/SATA front drive backplane and two 8 x 2.5" NVMe front drive backplanes (Gen 4).

To connect power cables for the front backplane(s), refer to Backplanes: server models with 2.5-inch front drive bays.

SAS/SATA cable routing​

Connections between connectors: 1 ↔ 1, 2 ↔ 2, 3 ↔ 3, ... n ↔ n
