Marketing Information

The M.2 adapters carry a one-year, customer-replaceable unit (CRU) limited warranty. When the adapters are installed in a supported server, the adapters assume the server's base warranty and any warranty upgrades.

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 module, or directly on the system board.
