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. 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 RAID­1 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).

Features

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
Supports Secure Boot
Adapter and drive firmware update using Lenovo firmware tools
Management via I2C interface

ThinkSystem M.2 Drives and M.2 Adapters 2

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 can also select zero drives and add drives as a field upgrade.

* These drive options do not have power-loss capacitors, which means they do not have protection against
a potential loss of data when a write operation is underway just as a power outage occurs. As a result,
these drives are not recommended for general purpose storage functions.
