Lenovo 4XH7A61078 SR650 V2 8X2.5 Anybay BP

Lenovo 4XH7A61078 SR650 V2 8x2.5 Anybay Backplane

Overview

The Lenovo 4XH7A61078 is the 8-bay 2.5-inch Anybay backplane designed for the ThinkSystem SR650 V2 rack server. "Anybay" means the backplane supports NVMe, SAS, and SATA drives interchangeably in the same bay positions — giving storage architects the ability to mix drive protocols within a single server without replumbing the backplane. At 0.80 lb and fitting within the SR650 V2's front-bay envelope (6.80 x 7.70 x 6.00 in), this is a direct swap or expansion component, not a standalone device.

If you are configuring an SR650 V2 for a surveillance workload — high-ingest NVR storage, video analytics inference with fast local storage, or hybrid SAS archive with NVMe cache — the 4XH7A61078 is the component that makes mixed-protocol storage practical in a 2U footprint.

Key Features

• Anybay Protocol Flexibility: A single backplane that accepts NVMe U.2, SAS, or SATA 2.5-inch drives in any bay. In practice, this means you can run NVMe for your hot analytics tier and SAS or SATA for bulk video retention without requiring separate backplane assemblies or additional cabling harnesses — a real reduction in configuration complexity.
• 8-Bay 2.5-Inch Configuration: Eight front-accessible drive slots in the 2.5-inch small-form-factor. For surveillance storage, 8x 2.5-inch SAS/NVMe slots in a 2U server gives you dense capacity per rack unit — particularly relevant when combining high-capacity 2.5-inch SAS HDDs with one or two NVMe cache drives.
• SR650 V2 Platform Fit: Built and validated specifically for the ThinkSystem SR650 V2 chassis. Using the correct Lenovo-sourced backplane ensures proper signal integrity, hot-swap detection, and firmware-level drive management through the RAID adapter and XClarity management stack — substituting off-brand backplanes on this platform introduces compatibility risk that shows up during drive replacement under load.
• Compact, Low-Weight Component: At 0.80 lb, the 4XH7A61078 is designed for tool-assisted installation within the SR650 V2 chassis. The 6.80 x 7.70 x 6.00 in footprint confirms this is a chassis-internal assembly, not an external enclosure add-on.
• UNSPSC 43211600 Classification: Classified under Computer Storage Products — confirms this component is categorized as server storage infrastructure, relevant for procurement teams that require UNSPSC coding for purchase order systems or ERP integrations.

Integration and Compatibility

The 4XH7A61078 is designed exclusively for the Lenovo ThinkSystem SR650 V2 platform. Before ordering, confirm your SR650 V2 chassis revision and existing backplane configuration against the Lenovo SR650 V2 Configuration Guide — Lenovo publishes backplane-to-riser and backplane-to-RAID-adapter pairing requirements that must be satisfied for NVMe bifurcation to function correctly. Mixing backplane generations within the same chassis is not supported. For surveillance deployments, pair this backplane with a Lenovo ThinkSystem RAID adapter that supports the drive protocols you intend to deploy — NVMe drives typically connect via PCIe retimer or direct CPU lanes depending on SR650 V2 configuration, not through the RAID HBA.

For teams building out network video recorders or edge analytics nodes on Lenovo ThinkSystem hardware, reviewing a storage planning guide before finalizing drive and backplane selection will save a configuration cycle. The broader Lenovo server and storage line includes complementary components — caddies, RAID adapters, and drive options — that pair with this backplane in a validated SR650 V2 build.

Frequently Asked Questions

Q: What server is the Lenovo 4XH7A61078 compatible with?

A: The 4XH7A61078 is the 8x2.5 Anybay backplane for the Lenovo ThinkSystem SR650 V2. It is not a universal backplane — confirm chassis revision compatibility before ordering.

Q: What drive types does the Anybay backplane support?

A: Anybay backplanes support NVMe, SAS, and SATA 2.5-inch drives interchangeably in the same bay positions. Drive protocol support per bay may depend on the RAID adapter and SR650 V2 configuration — consult the Lenovo SR650 V2 Configuration Guide.

Q: What are the dimensions and weight of the 4XH7A61078?

A: The backplane measures 6.80 x 7.70 x 6.00 inches and weighs 0.80 lb. It is an internal chassis component, not a standalone external device.

Q: Is the 4XH7A61078 a new or refurbished component?

A: This is a factory-new, genuine Lenovo component sourced through authorized distribution channels — no grey-market, no parallel imports.

Q: Can this backplane be used in an SR650 (non-V2) chassis?

A: Evidence does not confirm cross-generation compatibility. The 4XH7A61078 is specified for the SR650 V2 platform. Verify against Lenovo's official compatibility matrix before installing in any other chassis variant.

The 4XH7A61078 sits at the intersection of storage flexibility and platform specificity — it is an 8-bay 2.5-inch Anybay backplane that fits only the SR650 V2, but within that chassis it removes the usual commitment to a single drive protocol. That 6.80 x 7.70 x 6.00 in, 0.80 lb component is what lets you deploy NVMe for analytics cache alongside SAS or SATA for video retention in the same 2U server.

Technical Highlights:

• Anybay Multi-Protocol: NVMe, SAS, and SATA 2.5-inch drives share the same 8 bays — no separate backplane required per protocol, which keeps the SR650 V2 cabling clean and simplifies drive upgrades mid-lifecycle.
• Physical Form Factor: At 0.80 lb and 6.80 x 7.70 x 6.00 in, this component fits entirely within the SR650 V2 front-bay assembly. There is no external footprint — this is a chassis-internal install, not a bolt-on accessory.
• UNSPSC 43211600: Properly coded as a Computer Storage Product — procurement teams running SAP or Oracle purchasing workflows can classify this correctly without a manual override.

Deployment Considerations:

• Backplane-to-RAID-adapter pairing is mandatory: NVMe bifurcation on the SR650 V2 requires specific PCIe lane routing that must be validated in the Lenovo Configuration Guide before the order is placed — a mismatch will leave NVMe bays non-functional at POST.
• This component is SR650 V2-specific. Do not assume interchangeability with SR650 Gen 1 or other ThinkSystem 2U platforms — the physical connectors and signal routing differ across generations.

For surveillance infrastructure teams building a 2U NVR or edge analytics node on the ThinkSystem SR650 V2, the 4XH7A61078 is the right backplane when the storage design requires NVMe for ingest speed and SAS/SATA for bulk retention — all in a single, front-serviceable bay assembly.
