ThinkSystem M.2 Drives and M.2 Adapters

Product Guide

M.2 is a solid-state drive (SSD) form factor primarily used as an operating system boot solution in

conventional rack and tower servers, or as small form factor storage offering for edge servers.

Lenovo ThinkSystem servers support M.2 drives in one of three ways, depending on the server selected:

One or two drives, mounted in an M.2 adapter, vertically in a dedicated slot

Two or four drives, mounted horizontally in an M.2 adapter

Installed directly on the system board

One example is the Dual M.2 Adapter, as shown in the following figure, with one 128GB M.2 drive partially

inserted. The second M.2 drive is installed on the other side of the adapter.

Did you know?

Many of the M.2 adapters include a built-in RAID controller and allows two installed M.2 drives to be

configured either as RAID-1, RAID-0, or two independent drives (JBOD mode).

The Dual M.2 Adapter features a Lenovo patented design that provides a tool-less method for attaching

back-to-back M.2 modules to the adapter.
