Lenovo 4C57A15020 SR850 V2 Rear 7MM SATA RAID KIT

Lenovo 4C57A15020 SR850 V2 Rear 7MM SATA RAID Kit

Overview

The Lenovo 4C57A15020 is a rear drive bay RAID kit designed for the ThinkSystem SR850 V2 rack server, adding rear-facing 7mm SATA drive support where the base configuration leaves that bay unpopulated. If your SR850 V2 deployment calls for a dedicated OS drive, a hot-spare, or a small local cache volume mounted at the rear of the chassis — without occupying a front bay slot — this kit provides the mechanical and interface infrastructure to do it. The SATA interface means compatibility with standard 7mm 2.5-inch SATA SSDs, which are widely available and straightforward to provision.

Compatibility

This kit is designed specifically for the Lenovo ThinkSystem SR850 V2 server platform. It is not a universal fit — confirm your chassis is the SR850 V2 variant before ordering, as Lenovo rear bay kits are model-specific and do not interchange between SR850 generations or across the server accessories line. The SATA interface is fixed; this kit does not support NVMe or SAS drives. Verify your server's current rear bay configuration against the Lenovo SR850 V2 options compatibility matrix to confirm the rear bay is unoccupied and the kit is not already factory-installed.
