Lenovo 4C57A80517 SR250 2.5" Anybay 10-Bay Backplane V2
Overview
The Lenovo 4C57A80517 is the SR250 2.5" Anybay 10-Bay Backplane V2, a factory-new, genuine Lenovo server component designed for the ThinkSystem SR250 platform. At 2.00 lb, this backplane slots into the SR250 chassis to support up to ten 2.5" drive bays via Anybay architecture — meaning a single backplane handles SAS, SATA, and NVMe drives depending on the controller and cabling configuration installed. That flexibility lets you mix storage tiers (spinning SATA for bulk capacity, NVMe for fast scratch or OS) in a single 1U footprint without swapping backplanes when your storage strategy changes.
Key Features
- Anybay 10-Bay Design: Supports up to ten 2.5" drive slots with SAS, SATA, and NVMe compatibility through a single backplane — eliminates the need to stock separate all-SAS or all-NVMe backplanes for different SR250 configurations.
- SR250 Platform Fit: Engineered specifically for the ThinkSystem SR250 chassis. Installing a backplane that isn't platform-matched risks connector misalignment, firmware incompatibility, and voided support — the 4C57A80517 avoids all three.
- 2.00 lb Component Weight: Lightweight enough for a single-technician swap during a planned maintenance window; no special tooling or heavy hardware handling required.
- V2 Revision: The V2 designation indicates a revised hardware iteration over the original SR250 backplane — verify with your Lenovo support channel that your SR250 firmware and controller are qualified for V2 before installation.
Integration & Compatibility
This backplane is designed for the Lenovo ThinkSystem SR250 server platform. Before ordering, confirm your SR250 chassis generation, installed storage controller (RAID adapter vs. onboard HBA), and current firmware level against Lenovo's compatibility matrix for the 4C57A80517. Anybay backplanes require specific cabling harnesses and controller support to enable NVMe — SAS/SATA operation is typically available with standard onboard connectivity. Consult Lenovo's server infrastructure documentation or your pre-sales engineering contact to validate the full drive and controller pairing before deployment.
Frequently Asked Questions
Q: What server is the 4C57A80517 backplane compatible with?
A: The 4C57A80517 is designed for the Lenovo ThinkSystem SR250 server platform. Confirm chassis generation and controller compatibility with Lenovo's official compatibility matrix before installation.
Q: What drive types does the Anybay backplane support?
A: Anybay architecture supports SAS, SATA, and NVMe 2.5" drives. NVMe support depends on the installed storage controller and cabling — standard onboard connectivity typically enables SAS/SATA only.
Q: What is the weight of the 4C57A80517?
A: The 4C57A80517 weighs 2.00 lb, making it a straightforward single-technician installation during a planned maintenance window.
Q: Is this a V2 revision and does that matter for my existing SR250?
A: Yes, this is the V2 revision of the SR250 2.5" Anybay 10-Bay Backplane. Verify that your SR250 firmware and storage controller are qualified for the V2 part before swapping from an original-revision backplane.
Q: Is the 4C57A80517 a genuine Lenovo part?
A: Yes. This is a factory-new, genuine Lenovo component sourced through established distribution channels — no grey-market, no parallel imports.
The Lenovo 4C57A80517 is a component-level buy — the kind of part you order when you're expanding an SR250 storage configuration or replacing a failed backplane rather than spinning up a net-new server. At 2.00 lb, it's a clean field-swap, but the V2 revision designation is the detail that matters most before this ships to a technician.
Technical Highlights:
- Anybay Flexibility: A single backplane that speaks SAS, SATA, and NVMe eliminates the need to stock separate backplane SKUs for different SR250 storage tiers — meaningful when you're managing a fleet of SR250s with varied workloads.
- 10-Bay 2.5" Capacity: Ten drive slots in a 1U chassis gives the SR250 solid density for edge compute or small datacenter workloads where rack space is constrained.
- 2.00 lb Weight: Lightweight enough that a field technician can carry multiple units and swap without additional lift equipment — relevant for distributed deployments with multiple SR250 nodes.
Deployment Considerations:
- Anybay NVMe capability is controller-dependent — if you're expecting NVMe operation, confirm your SR250's installed storage adapter is NVMe-capable before ordering, or you'll be running SAS/SATA-only regardless of the backplane.
- The V2 revision may not be backward-compatible with every SR250 chassis build date — cross-reference Lenovo's Field Replaceable Unit (FRU) documentation against your system's machine type and model before purchasing.
Best fit for SR250 fleet operators who need a reliable, genuine backplane replacement or expansion part — particularly in edge surveillance server builds or branch datacenter environments where ThinkSystem SR250s handle NVR or storage workloads.
