Lenovo 4C57A15024 SR860 V2 2.5-Inch SAS/SATA Drive Backplane

Overview

The Lenovo 4C57A15024 is a 2.5-inch drive backplane designed for the ThinkSystem SR860 V2 platform, supporting both SAS and SATA drive interfaces. Backplanes at this level handle the signal routing and power distribution between installed drives and the server's HBA or RAID controller — replacing or expanding drive bay capacity without reworking cabling to each individual drive. For storage-dense deployments running surveillance archives, AI inference datasets, or enterprise NAS workloads, having the correct backplane part is non-negotiable: a mismatch between backplane and chassis generation means the drive bays simply won't register correctly in the system.

At 60 lb, this is a substantial server-class component — expect to handle it as part of a full SR860 V2 chassis assembly or service operation, not a standalone shelf install.

Key Features

• Dual-Protocol Interface (SAS and SATA): Supporting both SAS and SATA simultaneously means you're not locked into a single drive tier. Deploy SAS drives where sustained throughput and duty-cycle endurance matter, and SATA where cost-per-terabyte is the priority — the 4C57A15024 accommodates mixed populations without an adapter or protocol converter in the signal path.
• SR860 V2 Platform Fit: Engineered for the ThinkSystem SR860 V2 chassis, this backplane slots into the correct mechanical bay alignment and connector positions for that generation. Using a backplane from a different SR860 revision or a different server family is a common service error — confirm the chassis generation before ordering.
• 2.5-Inch Bay Format: The 2.5-inch form factor supports the high-density SAS/SATA SSD and HDD lineup common in enterprise storage tiers — relevant whether you're building out a surveillance recording server, a structured data store, or a mixed-workload node.

Integration and Compatibility

The 4C57A15024 is intended for use within the Lenovo ThinkSystem SR860 V2 server. Compatibility with specific HBA and RAID adapters depends on the full SR860 V2 configuration; verify against the server storage components in your planned build. The SAS/SATA dual-protocol design aligns with the enterprise server storage ecosystem supported by the SR860 V2 platform. If you are spec'ing storage for a IP camera recording infrastructure or a video analytics node, confirm that the SR860 V2 chassis you are pairing this backplane with matches your HBA controller generation — network infrastructure feeding the recording server should also be sized for the aggregate write throughput the drive count will demand.

Frequently Asked Questions

Q: Is the Lenovo 4C57A15024 compatible with the SR860 V2 only, or does it also fit earlier SR860 revisions?

A: Based on available evidence, this backplane is designated for the SR860 V2. Backplanes are generation-specific due to chassis bay dimensions and connector positioning — do not assume backward compatibility with the original SR860 without verifying Lenovo's compatibility matrix for your chassis serial range.

Q: Does this backplane support NVMe drives in addition to SAS and SATA?

A: The evidence identifies SAS and SATA interface support. NVMe compatibility is not confirmed in the available documentation — if NVMe is a requirement, verify against the full SR860 V2 option documentation before ordering.

Q: What is the weight of the 4C57A15024?

A: The listed weight is 60 lb. This reflects the component as shipped and is relevant for rack service planning, particularly in high-density configurations where multiple components are handled in a single maintenance window.

Q: What UNSPSC code does this product carry?

A: The 4C57A15024 carries UNSPSC code 43211600, which covers computer storage products — relevant for procurement systems that require commodity code classification for enterprise purchasing workflows.

Marty Allison

The 4C57A15024 is a platform-specific component — and that specificity is exactly the point. This SR860 V2 backplane supports both SAS and SATA drive interfaces, which matters when you're building out a storage node where drive mix is determined by workload tier rather than a single vendor's lineup. At 60 lb, this isn't something you drop into a cart without confirming your chassis generation first.

Technical Highlights:

• SAS + SATA Dual Protocol: Signal routing for both SAS and SATA means a single backplane can serve mixed drive populations — SAS for high-cycle write workloads, SATA for cost-optimized capacity tiers, no protocol bridge required.
• 2.5-Inch Bay Format: Supports the enterprise SSD and HDD lineup that dominates surveillance archive and data-intensive server builds in the SR860 V2 class.
• UNSPSC 43211600: Properly classified as a computer storage product — matters for procurement teams running commodity-coded purchase orders through ERP or procurement platforms.

Deployment Considerations:

• Backplane generation must match the SR860 V2 chassis exactly — connector positions and bay alignment are not interchangeable across SR860 revisions; confirm your chassis build date and part revision before issuing a PO.
• NVMe support is not confirmed from available evidence — if your storage architecture requires NVMe drive bays, validate separately against Lenovo's SR860 V2 option catalog rather than assuming protocol coverage from the dual SAS/SATA designation.

Best fit for a ThinkSystem SR860 V2 storage expansion or backplane service replacement in a surveillance recording server, AI inference node, or enterprise NAS build where SAS and SATA drive mix is already part of the architecture.
