Lenovo 4XH7A08791 internal solid state drive M.2 480 GB PCI Express 2.0 3D TLC

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 upported M.2 adapter or directly on the system board. On the ThinkSystem SR150, SR250 and ST250, a single M.2 drive is installed directly on the system board. On all other support ThinkSystem servers, 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 server. With two M.2 drives configured, the drives are configured by default as a RAID-1 mirrored pair for redundancy. - 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 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. - 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 - 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 - 6 Gbps SATA host interface (connects to the PCH) - Supports one 6 Gbps SATA M.2 drive** - Drive firmware update using Lenovo firmware tools - VPD reporting of adapter inventory
