Lenovo 4XB7A69400 SR670 V2 2.5 NVME 2X2-BAY

Lenovo 4XB7A69400 SR670 V2 2.5" NVMe 2x2-Bay Storage Upgrade

Overview

The Lenovo 4XB7A69400 is a 2x2-bay 2.5" NVMe storage upgrade kit designed for the ThinkSystem SR670 V2 server platform. If you're expanding NVMe capacity in an SR670 V2 chassis, this kit provides the physical bay infrastructure to add high-speed, low-latency NVMe drives without replacing the host system. The NVMe interface bypasses the legacy SAS/SATA bottleneck entirely — connecting storage directly to the PCIe fabric — which matters when running latency-sensitive workloads like video surveillance analytics, VMS databases, or AI inference pipelines that depend on fast sequential and random I/O.

Sourced as genuine Lenovo hardware through commercial distribution channels, the 4XB7A69400 carries the UNSPSC commodity code 43211600, classifying it within the data storage devices category — relevant for procurement systems that require commodity-level classification for purchase order routing or IT asset management.

Key Features

• NVMe Interface: Direct PCIe-attached storage eliminates the SAS/SATA controller layer, reducing latency and increasing throughput versus traditional drive configurations — meaningful on workloads where storage I/O is a bottleneck, such as multi-stream video recording or database-heavy VMS deployments.
• 2x2-Bay 2.5" Configuration: The dual two-bay layout provides physical capacity for up to four 2.5" NVMe drives, letting you scale SR670 V2 storage without reconfiguring the core chassis. Useful when an initial deployment needs headroom for future storage expansion without a forklift upgrade.
• SR670 V2 Platform Fit: Engineered specifically for the ThinkSystem SR670 V2, meaning the mechanical fit, backplane signaling, and power delivery are validated for this chassis — no compatibility guesswork compared to generic third-party bay solutions.
• Commercial Weight Profile (10 lb): At 10 lb, the kit is a substantial chassis-integrated component — factor this into rack weight calculations if the SR670 V2 is already near its rack unit weight limit, particularly in dense four-post deployments.

Integration & Compatibility

The 4XB7A69400 is documented under UNSPSC 43211600 (data storage devices) and is compatible with the Lenovo ThinkSystem SR670 V2 server family. For deployments within network video recorder or AI compute stacks built on Lenovo ThinkSystem servers, confirm NVMe drive compatibility and backplane firmware levels with Lenovo's ServerProven list before provisioning drives. If you're building or expanding a surveillance storage infrastructure, pair this kit with NVMe drives validated on the SR670 V2 platform to avoid interoperability issues at scale. Review your network infrastructure and overall rack plan alongside storage expansion to ensure the full system is sized correctly.

Frequently Asked Questions

Q: What server is the 4XB7A69400 compatible with?

A: The 4XB7A69400 is designed for the Lenovo ThinkSystem SR670 V2 server platform. Verify compatibility with your specific SR670 V2 configuration using Lenovo's ServerProven compatibility tool before ordering.

Q: What drive interface does the 4XB7A69400 support?

A: This kit supports NVMe drives via the PCIe-attached NVMe interface — not SAS or SATA. Ensure your drive selection matches the NVMe specification.

Q: How many drives does this kit accommodate?

A: The 2x2-bay configuration supports up to four 2.5" NVMe drives across two pairs of bays.

Q: What does the UNSPSC code 43211600 indicate?

A: UNSPSC 43211600 classifies this product under data storage devices — useful for procurement systems, ERP integrations, and purchase order routing that rely on commodity-level classification.

Q: What is the weight of the 4XB7A69400?

A: The kit weighs 10.00 lb. Factor this into your rack weight budget when planning SR670 V2 deployments in weight-constrained environments.

James Everett

When a client asks me about the 4XB7A69400, my first question is always: what NVMe drives are you pairing it with, and have you confirmed them on Lenovo's ServerProven list? The kit's NVMe interface is its core value proposition — PCIe-direct storage is the right architecture for high-throughput workloads — but that advantage disappears immediately if you populate the bays with drives that haven't been validated for the SR670 V2 platform.

Technical Highlights:

• NVMe Interface: PCIe-attached storage bypasses the SAS/SATA controller entirely — the correct choice for latency-sensitive workloads like multi-stream 4K video recording or AI inference where storage I/O is measured in microseconds, not milliseconds.
• 2x2-Bay 2.5" Layout: Four drive slots across two bay pairs gives you meaningful expansion headroom in the SR670 V2 chassis without committing to a full storage shelf — a practical fit for phased capacity growth.
• Platform-Specific Engineering: At 10 lb, this is a substantial chassis component — the mechanical and electrical design is specific to the SR670 V2, which means the backplane signaling and power delivery are validated rather than adapted from a generic bay solution.

Deployment Considerations:

• Confirm your target NVMe drive models against Lenovo's ServerProven compatibility database before procurement — the SR670 V2 platform has validated drive lists, and off-list drives can introduce instability at scale.
• At 10 lb, account for this kit in your per-rack weight calculations, particularly in high-density four-post racks where multiple SR670 V2 units are stacked.

This kit fits best in SR670 V2 deployments that are expanding NVMe storage capacity for video analytics or AI inference workloads — environments where the I/O profile demands PCIe-direct bandwidth and the operator needs validated, platform-native hardware rather than a generic bay adapter.
