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.


Features of the ThinkSystem M.2 solution:
•Hardened boot media that does not use a drive bay
•Both mechanically & electronically designed to be more robust than any prior implementation
•Design provides hardware mirroring of two M.2 SSDs
•M.2 SSDs have higher mean time between failures (MTBF) than SD cards or USB keys
•Tool-less, patented clip design that supports back to back connector layout, providing simple install in limited space.


Features of the Dual M.2 Adapter:
•PCIe 2.0 x2 host interface (connects to the PCH)
•Based on the Marvell 88SE9230 6 Gbps SATA controller
•Supports one or two 6 Gbps SATA M.2 drives**
•Supports 3 different physical sizes of M.2 drives: 42mm (2242), 60mm (2260) and 80mm (2280)
•RAID functionality provided by the M.2 adapter
•RAID 1 by default; also supports RAID 0 and JBOD
•UEFI-based settings to enable/disable RAID mode and to review inventory
•Adapter and drive firmware update using Lenovo firmware tools
•Management via I2C interface


Features of the Single M.2 Adapter:
•6 Gbps SATA host interface (connects to the PCH)
•Supports one 6 Gbps SATA M.2 drive
•Supports 3 different physical sizes of M.2 drives: 42mm (2242), 60mm (2260) and 80mm (2280)
•Drive firmware update using Lenovo firmware tools
•Management via I2C interface
•VPD reporting of adapter inventory

• 2242, 2260 and 2280 are the industry terms for the M.2 drive dimensions. For example, 2280 corresponds to a drive that is 22mm wide and 80mm long.
  ** When using configure-to-order (CTO), you will be required to select two M.2 drives when configuring the Dual M.2 Adapter.
