The ST250 V2 server supports two M.2 form-factor SATA drives installed in an M.2 adapter attached to a dummy PCIe adapter. The PCIe adapter is in turn installed in a PCIe slot. The M.2 adapter is connected via cables to the system board; the edge connector of the PCIe adapter only provides physical support and does not provide PCIe signals or power.


The M.2 SATA/NVMe 2-Bay Enablement Kit has the following features when installed in the SR250 V2:
Supports one or two M.2 SATA drives
Support 42mm, 60mm, 80mm and 110mm drive form factors (2242, 2260, 2280 and 22110)
JBOD native support; no built-in RAID support (RAID can be enabled via Intel VROC)
Supports monitoring and reporting of events and temperature through I2C
Firmware update via Lenovo firmware update tools
