Lenovo Thinksystem M.2 Enablement Kit 7y37a01092
Introduction
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 with the addition of a supported M.2 adapter.
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 ThinkSystem server. With two M.2 drives configured, the drives are configured by default as a RAID-1 mirrored pair for redundancy.
There are two M.2 adapters supported:
- 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
Tip: The M.2 adapters are also referred to as enablement kits. In the product publications, they are referred to as M.2 backplanes. These terms are interchangable.
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.

Did you know?
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.
The Dual M.2 Adapter also includes 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).
