Lenovo 4XH7B04175 SR630 V4 M.2 RAID B540D-2HS Sata/nvme

Lenovo 4XH7B04175 SR630 V4 M.2 RAID Adapter

Overview

The Lenovo 4XH7B04175 is an M.2 RAID adapter — specifically the B540D-2HS configuration — designed for the ThinkSystem SR630 V4 server platform. It supports both SATA and NVMe M.2 drives in a single backplane assembly, giving you the flexibility to mix storage protocols without swapping hardware mid-deployment. If your SR630 V4 build calls for fast NVMe boot or caching drives alongside SATA data drives, the 4XH7B04175 handles both without requiring separate adapters for each bus type.

For integrators building server infrastructure around the SR630 V4, selecting the correct M.2 adapter at BOM stage matters — Lenovo's ThinkSystem line uses model-specific backplane assemblies that are not interchangeable across chassis generations. This adapter is sourced factory-new with manufacturer warranty coverage.

Key Features

• Dual-protocol M.2 support (SATA + NVMe): A single adapter handles both bus types — useful when pairing an NVMe cache tier with a SATA boot volume, avoiding the cost and slot consumption of two separate adapters.
• M.2 form factor: The compact M.2 interface keeps the adapter footprint minimal inside the SR630 V4 chassis, preserving PCIe slot availability for network or storage expansion cards that matter more to your workload.
• SR630 V4 platform fit: Designed specifically for the SR630 V4 chassis — not a generic card. Confirm your exact chassis generation before ordering; this is not backward-compatible with SR630 V2/V3 variants without verification from Lenovo's compatibility matrix.
• B540D-2HS configuration: The two-slot (2HS) designation means it accommodates two M.2 drives simultaneously — relevant for mirrored boot configurations or a boot-plus-cache pairing without additional hardware.

Integration & Compatibility

The 4XH7B04175 is validated for use within the Lenovo ThinkSystem SR630 V4 server. Before deploying, cross-reference Lenovo's data center infrastructure compatibility tool for your specific SR630 V4 firmware level and drive selections — M.2 NVMe drive support in particular can be firmware-dependent on this platform. For full rack server accessory planning, confirm slot allocation and drive wattage against your chassis power budget.

Frequently Asked Questions

Q: What server platform is the 4XH7B04175 compatible with?

A: The 4XH7B04175 is designed for the Lenovo ThinkSystem SR630 V4. It is not a universal M.2 adapter — platform fit should be verified against Lenovo's compatibility matrix before ordering.

Q: Does the 4XH7B04175 support both SATA and NVMe M.2 drives?

A: Yes. The B540D-2HS configuration supports both SATA and NVMe M.2 interfaces, allowing mixed-protocol drive installations in the same backplane.

Q: How many M.2 drives does the 4XH7B04175 support?

A: The 2HS (two half-slim) designation indicates support for two M.2 drives simultaneously.

Q: Where is the 4XH7B04175 manufactured?

A: Country of origin is Mexico (MX), per distribution records.

Ted Perry

The 4XH7B04175 is one of those BOM line items that looks trivial until you're standing in front of a half-built SR630 V4 wondering why your NVMe boot drive isn't being detected — because the wrong M.2 backplane variant was ordered. The dual-protocol SATA/NVMe support in the B540D-2HS configuration is the practical reason to spec this part specifically rather than reaching for a cheaper single-protocol alternative.

Technical Highlights:

• Dual SATA/NVMe on one adapter: Both M.2 bus types on a single backplane means one BOM line item covers your boot-plus-cache topology — no secondary PCIe adapter needed.
• Two-drive capacity (2HS): The half-slim dual-slot layout supports simultaneous population of two M.2 drives, enabling a mirrored boot pair or a heterogeneous NVMe+SATA pairing within the same assembly.
• SR630 V4 platform specificity: Lenovo ThinkSystem adapters are chassis-generation locked — the 4XH7B04175 is validated for V4, not V2 or V3. Ordering the wrong generation means a non-functional backplane that won't seat correctly.

Deployment Considerations:

• Before finalizing the drive selection, confirm NVMe drive compatibility at your target SR630 V4 firmware revision — Lenovo's support matrix lists drive-specific firmware minimums that can catch you at commissioning if skipped.
• The 10 lb shipping weight suggests this ships as part of a larger kit or in protective packaging; verify the contents against your PO before rack installation to avoid a field trip back to the stockroom.

Best fit: SR630 V4 deployments where a fast NVMe volume and a SATA volume need to coexist in the M.2 bay without consuming a full-height PCIe slot — common in edge compute nodes and compact data center builds where slot real estate is constrained.
