Lenovo 4Z57A88894 SR250 V3 SATA and NVMe Backplane Kit

Overview

The Lenovo 4Z57A88894 is a dual-interface backplane kit designed for the ThinkSystem SR250 V3 server, adding two 3.5-inch SATA bays and two 3.5-inch NVMe bays in a single kit. If you are expanding local storage on an SR250 V3 — whether for surveillance footage retention, log archiving, or edge compute data — this kit provides the physical bay infrastructure required to seat and connect additional drives without improvised cabling or unsupported configurations. Installing 4Z57A88894 keeps the drive topology within Lenovo's validated hardware matrix, which matters for firmware compatibility and support coverage.

Compatibility

This kit is designed specifically for the Lenovo ThinkSystem SR250 V3 server platform. It is not a universal backplane — do not attempt to fit it into SR250 (V1), SR250 V2, or other ThinkSystem 1U platforms. Verify your server's chassis generation before ordering. For compatible drive and cable pairings, consult Lenovo's ServerProven configurator using part number 4Z57A88894, as supported cables are model-dependent and must be sourced separately to complete the installation.

Installation Notes

This is a server storage accessory — cables are not included and must be ordered separately based on your SR250 V3 drive configuration. Confirm cable compatibility through Lenovo's parts matrix before deployment. Installation should follow ThinkSystem SR250 V3 hardware maintenance procedures; incorrect backplane seating can prevent drive detection at POST.
