Lenovo 4C57A15025 SR860 V2 2.5-Inch Anybay Backplane

Overview

The Lenovo 4C57A15025 is a 2.5-inch Anybay backplane designed for the ThinkSystem SR860 V2 rack server platform. Anybay architecture means the backplane supports multiple drive interface types — NVMe, SAS, and SATA — through a single unified connector design, giving you flexibility to mix drive technologies in the same bay without swapping backplanes as storage requirements evolve. At 60 lb shipping weight, this is a substantial server-grade component intended for professional data center installation.

Key Features

• Anybay Multi-Protocol Support: A single backplane design that accommodates NVMe, SAS, and SATA drives means you can shift storage strategy — from spinning disk to all-flash — without replacing the backplane assembly. That flexibility matters in environments where workload profiles change over a 3–5 year server lifecycle.
• SR860 V2 Platform Fit: Built specifically for the ThinkSystem SR860 V2 chassis. Using the correct OEM backplane (4C57A15025) ensures compatibility with the server's expander, cable routing, and firmware-level drive management — third-party alternatives frequently introduce intermittent recognition failures under load.
• 2.5-Inch Drive Bay Format: The 2.5-inch form factor supports high-density SSD and SAS drive configurations typical in compute-intensive or storage-dense deployments where drive count per rack unit matters.

Integration & Compatibility

The 4C57A15025 is designed for installation into the Lenovo ThinkSystem SR860 V2 server. Verify your SR860 V2 configuration and existing backplane slot before ordering — the SR860 V2 supports multiple backplane configurations depending on the storage option selected at build time. Consult your SR860 V2 hardware maintenance manual to confirm the correct backplane part number for your specific bay position and cable set.

Frequently Asked Questions

Q: What server is the 4C57A15025 compatible with?

A: The 4C57A15025 is a backplane component for the Lenovo ThinkSystem SR860 V2 rack server. It is not a universal part — confirm your SR860 V2 configuration before ordering.

Q: What does "Anybay" mean on the 4C57A15025?

A: Anybay refers to Lenovo's backplane architecture that supports NVMe, SAS, and SATA drives through the same physical bays and connectors, eliminating the need for dedicated per-protocol backplanes.

Q: What drive size does the 4C57A15025 support?

A: The 4C57A15025 is a 2.5-inch backplane, supporting 2.5-inch form factor drives — including SSD and SAS/SATA HDDs in the 2.5-inch standard.

Q: Is this a new or refurbished component?

A: The 4C57A15025 is sourced as a factory-new, genuine Lenovo component — no grey-market, no parallel imports.

Marty Allison

The 4C57A15025 is one of those parts that looks unremarkable until the server won't recognize a drive bay and you're tracing the fault at 2 AM. The Anybay design is genuinely useful — I've worked with SR860 V2 builds where the storage roadmap changed mid-project, and having a backplane that handles NVMe and SAS from the same slots avoided a chassis re-work that would have cost more than the drives themselves.

Technical Highlights:

• Anybay Architecture: Single backplane accommodates NVMe, SAS, and SATA — reduces spare-parts complexity in mixed-protocol storage environments.
• Platform-Specific Fit: Engineered for the SR860 V2 chassis; OEM fit avoids the firmware-level drive detection issues that show up with non-OEM backplanes under sustained I/O load.
• 2.5-Inch Format: Supports high-density drive configurations where maximizing drive count per server unit is a design requirement.

Deployment Considerations:

• The SR860 V2 has multiple backplane configurations depending on the storage option ordered — cross-reference the hardware maintenance manual for your specific bay position before installing the 4C57A15025.
• At 60 lb shipping weight, plan for proper mechanical lift support during chassis installation; this is not a one-person component swap.

Best fit for SR860 V2 deployments adding or replacing storage bay assemblies in high-density compute or virtualization environments where mixed NVMe/SAS flexibility is a requirement.
