Lenovo 4XB7A80584 SR950 2.5 Sas/sata 2X2 BAY BP KIT V2

Lenovo 4XB7A80584 SR950 2.5" SAS/SATA 2x2 Bay Backplane Kit V2

Overview

The Lenovo 4XB7A80584 is a drive bay backplane kit designed to add or replace a 2x2 configuration of 2.5-inch drive bays in supported Lenovo server platforms. Supporting both SAS and SATA interfaces, this kit gives you flexibility to install either SAS drives for high-throughput workloads or SATA drives for cost-optimized capacity — without requiring a dedicated controller change. At 2.00 lb, it is a compact, tool-assisted field installation component suited for data center technicians performing drive bay configuration or repair on the SR950 platform.

Compatibility

This backplane kit is designed for the Lenovo ThinkSystem SR950 server platform. It is specifically built around the 2.5-inch small form factor drive bay standard. The dual SAS/SATA interface support means it pairs with a wide range of enterprise storage configurations, including SAS HDDs, SAS SSDs, and SATA SSDs typically deployed in database, virtualization, and high-availability workloads. Verify your SR950 chassis revision and existing backplane layout before ordering — the V2 designation indicates a revised hardware iteration, and mixing V1/V2 components in the same bay cluster is not recommended without confirming Lenovo's platform compatibility matrix for your specific chassis build date.

Installation Notes

Installation requires access to the SR950 chassis interior with standard server tooling. The 2x2 bay layout means this kit occupies a defined physical slot within the drive cage — confirm available bay positions against your current drive population before procurement. SAS and SATA signal cabling must be routed to the appropriate HBA or onboard controller port; verify cable reach and connector type for your specific SR950 configuration. Handle the backplane PCB by its edges to avoid static damage during installation.
