Lenovo 4XH7A60974 SR630 V2 Rear 2X2.5 NVME BP KIT

Lenovo 4XH7A60974 SR630 V2 Rear 2x2.5" NVMe Backplane Kit

Overview

The Lenovo 4XH7A60974 is a rear-mounted storage expansion kit designed for the ThinkSystem SR630 V2 rack server. It adds two 2.5" NVMe drive bays to the rear of the chassis — the right solution when front bays are fully committed and you need additional high-speed NVMe capacity without reconfiguring the primary storage layout. The NVMe interface bypasses the SATA/SAS controller stack, delivering direct PCIe-attached throughput that matters for latency-sensitive workloads: caching tiers, write-ahead logs, or fast OS/boot volumes in a dense compute environment. The 4XH7A60974 is a factory-new kit sourced through channel-direct distribution.

Compatibility

Designed specifically for the Lenovo ThinkSystem SR630 V2 (1U rack server). This kit is not cross-compatible with SR630 (V1), SR650, or other ThinkSystem series — the rear bay mechanical footprint and backplane connector layout are specific to the V2 chassis revision. Confirm your server's chassis generation before ordering; the SR630 V2 uses a distinct rear I/O cage compared to its predecessor. Compatible NVMe drives must be 2.5" U.2 or equivalent form factor supported by the SR630 V2 platform — consult the Lenovo ServerProven compatibility matrix for validated drive options.

Installation Notes

Installation requires access to the rear of the SR630 V2 chassis with the server powered down and removed from the rack. The backplane kit mounts into the designated rear drive cage position; no additional power cables beyond what the SR630 V2 rear bay supports are required, as the backplane draws from the existing rear power distribution. Verify that the installed processor and PCIe lane allocation in your specific SR630 V2 configuration supports rear NVMe — certain CPU or riser configurations may limit rear bay PCIe bandwidth availability. Weight of the complete kit is 10 lb.
