Lenovo 4XH7A08791 computer cooling system part/accessory Mounting kit

M.2 is a solid-state drive (SSD) form factor primarily used as an operating system boot solution. Lenovo ThinkSystem servers support M.2 drives either with the addition of a upported M.2 adapter or directly on the system board.

On the ThinkSystem SR150, SR250 and ST250, a single M.2 drive is installed directly on the system board.

On all other support ThinkSystem servers, the M.2 drives install into an M.2 adapter which in turn is installed in a dedicated slot on the system board of the server. With two M.2 drives configured, the drives are configured by default as a RAID-1 mirrored pair for redundancy.

- Single M.2 Adapter, which supports one M.2 drive; available as the ThinkSystem M.2 Enablement Kit
- Dual M.2 Adapter, which supports one or two M.2 drives; available as the ThinkSystem M.2 with Mirroring Enablement Kit

A Dual M.2 Adapter with one 128GB M.2 drive partially inserted is shown in the following figure. The second M.2 drive is installed on the other side of the adapter.
