Lenovo 4XB7A69395 SR670 V2 EDSFF 1x6-Bay Backplane

Overview

The Lenovo 4XB7A69395 is a backplane option kit for the ThinkSystem SR670 V2 server, configured to support a 1x6-bay EDSFF (E1.S) drive cage. EDSFF — Enterprise and Datacenter SSD Form Factor — is Intel's next-generation compact NVMe drive standard designed to pack high-density flash storage into a space-efficient footprint without the thermal and mechanical compromises of U.2 or M.2 alternatives. If your SR670 V2 deployment needs to expand into EDSFF-based NVMe storage, this backplane is the factory-correct path to do it.

At 10 lb, the 4XB7A69395 is a substantial mechanical assembly — this is not a cable kit or adapter bracket. It is a full backplane module with the drive connectors, signal routing, and mounting hardware needed to integrate a 6-drive EDSFF bay into the SR670 V2 chassis. Installation is a server-internal procedure requiring chassis access and, depending on your support contract, may need to be performed by qualified data center personnel.

Key Considerations

• Platform specificity: This backplane is engineered for the ThinkSystem SR670 V2. Do not assume cross-compatibility with other SR670 variants or unrelated ThinkSystem platforms — Lenovo server options are chassis-generation specific, and an incorrect backplane can prevent proper drive recognition or cause physical fit issues.
• EDSFF drive ecosystem: The 6-bay E1.S configuration supports high-density NVMe flash — appropriate for AI inference workloads, fast object storage tiers, or latency-sensitive database environments where U.2 bay count is insufficient.
• Weight as a planning signal: The 10 lb assembly weight is relevant for shipping and rack logistics — account for it when planning chassis rail load ratings alongside other installed components.

Frequently Asked Questions

Q: What server is the Lenovo 4XB7A69395 compatible with?

A: The 4XB7A69395 is designed for the Lenovo ThinkSystem SR670 V2 server. Compatibility with other ThinkSystem platforms is not confirmed by available evidence — verify with Lenovo's ServerProven compatibility tool before ordering for any other chassis.

Q: What drive type does the 4XB7A69395 support?

A: Based on the product name, this backplane supports EDSFF (E1.S) form factor drives in a 1x6-bay configuration. EDSFF is a compact NVMe SSD standard used in high-density datacenter storage deployments.

Q: What does this backplane weigh?

A: The 4XB7A69395 weighs 10.00 lb. This is a full mechanical backplane assembly, not a lightweight accessory — factor this into shipping and chassis handling planning.

Q: Is this a field-installable option?

A: The 4XB7A69395 is a server-internal hardware option. Installation requires chassis access. Whether it qualifies as a field-installable customer option depends on your active Lenovo support agreement — confirm with your support contract terms before proceeding without a Lenovo service technician.

The 4XB7A69395 is one of those parts where getting the order right the first time matters more than almost any other line item in a server BOM. At 10 lb, this is a full backplane assembly — not a cable or bracket — and it is chassis-specific to the SR670 V2. Order the wrong generation or variant and you are looking at a return, a delay, and a rack that sits idle.

Technical Highlights:

• EDSFF 1x6-Bay Configuration: Six E1.S drive slots in a single backplane module — purpose-built for environments where NVMe density per rack unit matters more than raw capacity from larger form factors.
• Platform-Matched Design: Engineered specifically for the ThinkSystem SR670 V2 chassis, which means connectors, signal routing, and physical mounting are validated at the factory level — no adaptation required.
• Assembly Weight (10 lb): Heavier than a typical option kit, which signals this is a complete mechanical subassembly with its own structural role in the chassis — handle and ship accordingly.

Deployment Considerations:

• Confirm your SR670 V2 chassis revision and existing backplane configuration before ordering — the SR670 V2 supports multiple storage bay configurations and not all backplane options are interchangeable within the same chassis generation.
• Available evidence covers only weight and UNSPSC classification — for interface specifications, power draw, and drive compatibility matrices, reference Lenovo's official ThinkSystem SR670 V2 product guide before finalizing the BOM.

This part fits best in planned datacenter builds or validated storage expansion projects for the SR670 V2 platform where the EDSFF NVMe tier is already in the architecture — not a speculative add-on purchase.
