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 supported M.2 adapter or directly on the system board.
Introduction
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.
