Lenovo 4XH7A61077 SR650 V2 12x3.5 Anybay Backplane

Overview

The Lenovo 4XH7A61077 is the 12-bay 3.5-inch Anybay backplane designed for the ThinkSystem SR650 V2 rack server. Anybay architecture means each of the twelve drive slots can accept either SAS/SATA HDDs or U.2 NVMe SSDs — giving you flexibility to mix spinning storage and flash within the same chassis without swapping backplanes. That matters in environments where storage strategy evolves over a server's service life: you can start with high-capacity SATA HDDs for bulk data and migrate individual slots to NVMe as performance demands grow.

At 10 lb, the 4XH7A61077 is a genuine Lenovo OEM component sourced factory-new — not a grey-market or pulled part. UNSPSC code 43211600 classifies it under computer hardware peripherals, confirming its role as a server infrastructure component rather than an end-user device.

Key Features

• 12x 3.5-inch Anybay slots: Each bay is protocol-agnostic — wire to SAS/SATA expanders for spinning drives or direct-attach NVMe for flash. No backplane swap required when you change media type, which reduces downtime during storage upgrades.
• SR650 V2 native fit: Engineered specifically for the ThinkSystem SR650 V2 chassis. OEM fitment means correct connector alignment, firmware compatibility, and no improvised cabling — critical in dense rack environments where misalignment causes intermittent drive faults.
• 10 lb shipping weight: Consistent with a fully populated 12-bay 3.5-inch assembly. Factor this into rack weight budgets when planning dense storage nodes — a fully loaded SR650 V2 can exceed typical floor-load thresholds in older data centers.

Integration and Compatibility

The 4XH7A61077 is designed for the Lenovo ThinkSystem SR650 V2 platform. Verify your SR650 V2 build configuration against Lenovo's ServerProven compatibility matrix before ordering — backplane selection depends on the specific riser and controller pairing in your chassis configuration. This backplane is not interchangeable with SR650 (V1) or SR650 V3 variants.

Frequently Asked Questions

Q: Is the 4XH7A61077 compatible with the original ThinkSystem SR650 (non-V2)?

A: No. The 4XH7A61077 is designed specifically for the SR650 V2 chassis. The original SR650 and SR650 V3 use different backplane assemblies. Verify compatibility against Lenovo's ServerProven matrix for your exact build.

Q: What drive types does the Anybay backplane support?

A: Anybay backplanes support both SAS/SATA (HDD or SSD) and U.2 NVMe SSDs in the same physical bay — without requiring a backplane swap. The specific protocol depends on how the backplane is cabled to the controller in your SR650 V2 configuration.

Q: Is this a genuine Lenovo OEM part?

A: Yes. The 4XH7A61077 is a factory-new, genuine Lenovo component sourced through authorized distribution channels — no grey-market or refurbished units.

Q: What is the weight of the 4XH7A61077?

A: The shipping weight is 10 lb.

Karl Wilson

The Lenovo 4XH7A61077 is a purpose-built backplane assembly for the ThinkSystem SR650 V2 — and the Anybay design is the key reason to specify it over a fixed SAS-only backplane. With 12 x 3.5-inch bays that can be individually assigned to SAS/SATA or NVMe depending on your cabling and controller configuration, this backplane gives you a migration path without a forklift upgrade.

Technical Highlights:

• Anybay protocol flexibility: Each of the 12 bays accepts SAS/SATA spinning drives or U.2 NVMe SSDs — a single backplane covers both bulk-capacity and high-IOPS storage tiers in the same SR650 V2 chassis.
• OEM-native fit: Engineered for the SR650 V2 chassis specifically — correct connector geometry, firmware recognition, and Lenovo warranty coverage. Aftermarket alternatives introduce misalignment risk and typically void ThinkSystem support agreements.
• 10 lb assembly weight: Relevant when planning rack density — account for this alongside drive population weights when calculating loaded chassis weight against floor load ratings in older facilities.

Deployment Considerations:

• Backplane selection in the SR650 V2 ecosystem is tightly coupled to your RAID/HBA controller and cabling kit — order the 4XH7A61077 alongside the correct signal cable assembly for your controller to avoid a return loop.
• Anybay does not mean all-NVMe without additional hardware — U.2 NVMe operation requires a compatible NVMe-capable controller or direct CPU attachment via the appropriate riser; confirm your SR650 V2 build supports the intended protocol before deploying NVMe drives.

This backplane is the right call for SR650 V2 deployments in video surveillance storage nodes, edge data centers, or enterprise NAS builds where storage media strategy may shift from HDD to NVMe within the server's operational life — Anybay preserves that option without a chassis replacement.
