Lenovo 4XH7A87139 Thinksystem V3 1U 10X2.5 NVME Backplane GEN5 Option KIT

Lenovo 4XH7A87139 ThinkSystem V3 1U 10x2.5" NVMe Gen5 Backplane Option Kit

Overview

The Lenovo 4XH7A87139 is a 1U rack-mount NVMe Gen5 backplane option kit that expands drive connectivity in ThinkSystem V3 servers configured for ten 2.5-inch NVMe drives. If you're building out high-throughput storage for latency-sensitive workloads — AI inferencing, real-time video analytics, or dense database deployments — Gen5 NVMe bandwidth is the tier where per-drive throughput stops being a bottleneck. This kit installs directly into supported ThinkSystem V3 1U chassis bays, providing the backplane interconnect needed to commission NVMe Gen5 drives where the base system ships without it or where a bay expansion is required. At 1.00 lb, the 4XH7A87139 is a lightweight field-installable component suited to both initial system builds and post-deployment storage upgrades.

Compatibility

Designed for the Lenovo ThinkSystem V3 server family in 1U form factor configurations that support a 10x2.5-inch NVMe drive bay layout. Verify your specific ThinkSystem V3 model's option compatibility matrix before ordering — not all V3 1U chassis configurations ship with or support every backplane variant. The NVMe interface aligns with PCIe Gen5 signaling requirements; pairing with Gen4 or earlier drives will work at reduced performance, but the backplane is purpose-built to deliver full Gen5 bandwidth when matched with compliant drives and a compatible system board. Consult Lenovo's ServerProven or the chassis option compatibility guide for your exact system model to confirm slot and connector support before procurement.

Installation Notes

Installation requires access to the server chassis drive bay section. Follow the ThinkSystem V3 maintenance manual for your specific chassis model — correct backplane seating and cable routing to the system board's NVMe controllers is required to register drives. Confirm the host server's firmware is current before commissioning Gen5 drives; some ThinkSystem V3 platforms required firmware updates to enable full Gen5 enumeration at initial V3 launch.
