Lenovo 4XB7A86631 Thinksystem SR860 V3 8X 2.5 Anybay Backplane Option KIT

Lenovo 4XB7A86631 ThinkSystem SR860 V3 8x 2.5" AnyBay Backplane Option Kit

Overview

The Lenovo 4XB7A86631 is an 8-bay 2.5" AnyBay backplane option kit for the ThinkSystem SR860 V3 server. AnyBay backplanes support mixed NVMe and SAS/SATA drive populations in the same bay row, giving administrators the flexibility to split storage tiers — fast NVMe for latency-sensitive workloads alongside higher-density SAS/SATA drives — without committing to a single protocol at configure time. This kit addresses the common deployment scenario where a base SR860 V3 configuration ships with fewer drive bays than the installed workload ultimately demands, allowing expansion during initial build-out or as capacity requirements grow.

Compatibility

Designed exclusively for the Lenovo ThinkSystem SR860 V3 platform. This kit is not cross-compatible with earlier SR860 generations (V1, V2) or other ThinkSystem 4-socket families such as the SR950 V3. Confirm your SR860 V3 chassis revision and existing backplane configuration against the Lenovo ServerProven compatibility matrix before ordering — AnyBay slot assignments and cable routing can vary by chassis sub-revision and existing drive bay population.

Installation Notes

Installation requires access to the SR860 V3 internal drive cage and appropriate Lenovo system cables for the AnyBay interface; verify cable kit availability separately as signal cables may not be included. Follow Lenovo's ESD handling procedures throughout — backplane PCBs are sensitive to static discharge. Consult the SR860 V3 hardware maintenance guide for torque specifications on backplane mounting hardware and proper connector seating procedure before powering the system.
