Lenovo 4XH7A61076 SR650 V2 8X2.5 NVME BP

Lenovo 4XH7A61076 SR650 V2 8x2.5" NVMe Backplane

Overview

The Lenovo 4XH7A61076 is a factory-new NVMe backplane designed for the ThinkSystem SR650 V2 server platform, providing eight 2.5-inch NVMe drive bay connections in a single assembly. If you are expanding storage density on an SR650 V2 node — whether for video archive, AI inference datasets, or high-throughput transaction workloads — this backplane is the direct-fit component that enables that expansion without requiring a chassis swap. At 0.90 lb and measuring 8.10 x 4.60 x 3.60 inches, it installs cleanly into the SR650 V2 drive cage with no field modification.

Key Features

• NVMe Interface: NVMe delivers substantially lower latency and higher queue depth than SAS or SATA backplanes — relevant when the SR650 V2 is running latency-sensitive workloads such as real-time video analytics indexing or database-backed VMS platforms where drive response time directly affects query throughput.
• 8x 2.5" Bay Capacity: Eight independent NVMe drive slots let you populate the backplane incrementally or fully — stage capacity as budgets allow rather than committing to a full build on day one. A fully populated backplane can support substantial raw NVMe capacity depending on drive selection.
• Precision Form Factor (8.10 x 4.60 x 3.60 in, 0.90 lb): Dimensioned specifically for the SR650 V2 chassis, this backplane installs without clearance issues or bracket adapters. Weight is low enough that a single technician can handle installation during planned maintenance windows.
• SR650 V2 Platform Fit: Sourced as a genuine Lenovo component, this backplane is matched to the SR650 V2's drive cage geometry, backplane connector pinout, and firmware management stack — avoiding the compatibility unknowns that come with third-party alternatives.

Integration and Compatibility

The 4XH7A61076 is specified for the ThinkSystem SR650 V2 server. Confirm your SR650 V2 chassis configuration — drive cage type and existing backplane population — before ordering. NVMe drive selection should be validated against the SR650 V2 Hardware Maintenance Manual and Lenovo ServerProven compatibility list to ensure controller and firmware support. This backplane does not include drives; storage media must be sourced separately and matched to the NVMe interface standard.

Frequently Asked Questions

Q: Which server is the 4XH7A61076 compatible with?

A: The 4XH7A61076 is a backplane designed for the Lenovo ThinkSystem SR650 V2 server platform. It is not a universal backplane and should not be installed in other ThinkSystem models without confirming chassis and connector compatibility.

Q: Does the 4XH7A61076 include NVMe drives?

A: No. The 4XH7A61076 is the backplane assembly only — NVMe drives are not included and must be sourced separately. Confirm drive compatibility against Lenovo ServerProven for the SR650 V2.

Q: What is the drive bay count and form factor?

A: The backplane supports eight 2.5-inch NVMe drives.

Q: What are the physical dimensions and weight of the 4XH7A61076?

A: Dimensions are 8.10 x 4.60 x 3.60 inches (L x W x H) and weight is 0.90 lb.

Q: Is the 4XH7A61076 a new or refurbished component?

A: The 4XH7A61076 is sourced factory-new through distribution — not refurbished or grey-market.

Jerry Tildsen

When I spec storage expansion for ThinkSystem SR650 V2 deployments, the 4XH7A61076 is the backplane I call out when the requirement is all-NVMe — eight 2.5-inch bays, NVMe interface throughout, and a form factor (8.10 x 4.60 x 3.60 in, 0.90 lb) that drops straight into the SR650 V2 cage without workarounds.

Technical Highlights:

• NVMe Interface: Eliminates the protocol translation overhead of SAS/SATA controllers — meaningful for workloads where storage latency shows up in application response time, such as VMS databases or real-time analytics pipelines.
• 8-Bay Capacity: Eight independent 2.5-inch slots give you flexibility to stage NVMe population in phases — start with two or four drives, fill to eight as workload grows, without touching the backplane itself.
• 0.90 lb Assembly Weight: Light enough for single-technician installation during a maintenance window; no second pair of hands needed to hold the assembly while seating connectors in a rack-mounted chassis.

Deployment Considerations:

• Verify your specific SR650 V2 chassis configuration — drive cage variant and existing backplane population — before procurement. The SR650 V2 supports multiple backplane configurations and not all cage slots accept this unit interchangeably.
• NVMe drive compatibility must be confirmed against Lenovo ServerProven; the backplane itself does not guarantee that any NVMe drive will be recognized and managed correctly by the SR650 V2 storage controller firmware.

Best fit for SR650 V2 nodes being built or upgraded for high-throughput NVMe storage pools — video archive servers, analytics platforms, or hyperconverged nodes where SAS/SATA bandwidth has become a bottleneck.
