Lenovo 4XH7A80459 SR630 V2 Rear 2X2.5 NVME BP KIT V2

Lenovo 4XH7A80459 SR630 V2 Rear 2x2.5" NVMe Backplane Kit

Overview

The Lenovo 4XH7A80459 is a rear drive bay expansion kit designed for the ThinkSystem SR630 V2 rack server. It adds two 2.5-inch NVMe bays to the rear of the chassis — a targeted upgrade for workloads that need fast, low-latency NVMe storage accessible from the back of the system without consuming front-bay real estate. If your SR630 V2 deployment runs NVMe-intensive applications such as caching tiers, logging volumes, or OS boot drives alongside a fully populated front bay, this kit addresses that constraint directly. The NVMe interface means drives installed here bypass the storage controller's SAS/SATA overhead, delivering the full bandwidth and latency profile of direct-attach PCIe storage.

Compatibility

The 4XH7A80459 is engineered specifically for the Lenovo ThinkSystem SR630 V2 1U rack server. It is not a universal backplane — fit and connector alignment are chassis-specific. Verify your SR630 V2 chassis revision supports the rear bay option before ordering; not all SR630 V2 configurations ship with the rear bay cutout populated. Compatible NVMe drives must be 2.5-inch U.2 or equivalent form factor supported by the SR630 V2 platform. Consult the server storage accessories section for compatible NVMe drives and cabling options. If you are configuring a full data center storage architecture with tiered NVMe and SAS, plan drive bay allocation at the design stage — retrofitting rear bays after initial deployment adds cabling work inside a 1U chassis.

Installation Notes

Installation is internal to the SR630 V2 chassis and requires powering down the server. The kit installs at the rear of the system board tray; access requires partial disassembly of the 1U chassis interior. NVMe signal and power cabling must be routed from the system board to the rear backplane — verify cable kit availability separately, as the backplane kit itself may not include all necessary cabling for your specific SR630 V2 build. Weight of the installed kit is 2.00 lb, a negligible addition to the server's rack load.
