M.2 drive backplane

This section provides cable routing information for the M.2 drives. Your server supports M.2 SATA/NVMe drive backplanes.

Locations of M.2 drive assemblies

The locations of M.2 drive assemblies vary in different configuration. The server has two locations for M.2 drive assemblies.

Cable routing for M.2 drives

FromTo
1 M.2 power1 M.2 power connector
2 M.2 signal2 7mm/M.2 signal port on the processor board (for SATA signal)
3 PCIe 8 (for NVMe signal, connected when two processors are installed)
4 PCIe 1 (for NVMe signal, connected when one processor is installed)
Note
The illustrations above take the M.2 drive assembly in the 2.5/3.5-inch drive chassis for an example. In the 16-EDSFF drive chassis, the cable routing method remains the same.
