M.2 drive backplane

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 of the M.2 drive backplanes​

• For the locations of M.2 connectors on the backplanes and the processor board, see M.2 backplane and M.2 drive replacement and System-board-assembly connectors for details.

• The following illustrations and tables list the M.2 drive backplanes supported:

  • M.2 x4 non-RAID SATA/NVMe 2-bay backplanes

  • M.2 x1 RAID NVMe 2-bay backplanes

  • M.2 RAID SATA/NVME 2-bay backplanes

  • M.2 backplane to SFF RAID adapters
