Lenovo 4XB7A69396 SR670 V2 2.5 SATA/SAS/NVME1X8 BP

Lenovo 4XB7A69396 SR670 V2 2.5" SAS/SATA/NVMe 1x8 Drive Backplane

Overview

The Lenovo 4XB7A69396 is a 2.5-inch, 1x8-bay drive backplane designed for the ThinkSystem SR670 V2 server platform. Supporting SAS, SATA, and NVMe interfaces in a single backplane, it gives storage architects flexibility to mix drive types within one bay group — useful when tiering between NVMe cache and SAS/SATA capacity drives without reconfiguring the chassis. If you're expanding or replacing the storage subsystem in an SR670 V2 deployment, this is the factory-matched backplane for that platform.

Key Features

• Dual-protocol SAS/SATA support: A single backplane that accepts both SAS and SATA 2.5-inch drives means you're not locked into one drive vendor or tier. SAS for enterprise reliability, SATA for cost-effective bulk capacity — the backplane handles both without an adapter.
• NVMe-capable bay design: The 1x8 bay arrangement supports NVMe alongside SAS/SATA, so you can slot high-performance NVMe SSDs where latency matters without requiring a separate all-NVMe backplane or PCIe riser reconfiguration.
• Platform-matched fit for SR670 V2: The 4XB7A69396 is a Lenovo option part for the ThinkSystem SR670 V2 specifically. Using the correct platform backplane avoids fitment issues, firmware compatibility gaps, and voided support agreements that come with aftermarket alternatives.
• 2.5-inch form factor, 1x8 configuration: Eight 2.5-inch bays in a single backplane module. In a dense server environment, 2.5-inch drives maximize spindle or flash count per U of rack space compared to 3.5-inch alternatives.

Integration & Compatibility

The 4XB7A69396 is designed for installation in the Lenovo ThinkSystem SR670 V2 server. Confirm your SR670 V2 chassis bay configuration and HBA/RAID controller before ordering — the SR670 V2 supports multiple backplane configurations and not every backplane option is compatible with every chassis variant. Verify against your SR670 V2 configuration guide or open a pre-sales engineering inquiry before purchasing if you're unsure which backplane your chassis requires.

Frequently Asked Questions

Q: Which server is the Lenovo 4XB7A69396 compatible with?

A: The 4XB7A69396 is a drive backplane option part for the Lenovo ThinkSystem SR670 V2 server platform. It is not a universal backplane — confirm compatibility with your specific SR670 V2 chassis configuration before ordering.

Q: What drive interfaces does the 4XB7A69396 support?

A: The backplane supports SAS, SATA, and NVMe interfaces, allowing you to install 2.5-inch drives of any of these types in the 1x8 bay group.

Q: What is the drive bay count and form factor?

A: The 4XB7A69396 is a 1x8 backplane, providing eight 2.5-inch drive bays in a single module.

Q: How much does the 4XB7A69396 weigh?

A: The unit weighs 10.00 lb as shipped.

Q: Can I mix SAS and SATA drives on this backplane?

A: The backplane supports both SAS and SATA interfaces, but whether you can mix drive types in the same bay group depends on your HBA or RAID controller configuration. Consult your SR670 V2 documentation for mixed-protocol drive rules.

Marty Allison

The 4XB7A69396 is a platform-specific backplane — the SAS/SATA/NVMe tri-protocol support in a single 1x8 module is the detail that matters most when you're configuring storage tiers in a ThinkSystem SR670 V2. If you're sourcing this as a spare or an expansion option, make sure you've cross-referenced it against your chassis bay slot assignment before the unit ships.

Technical Highlights:

• Tri-protocol interface (SAS/SATA/NVMe): One backplane accommodates all three drive interface types in 2.5-inch form factor — reduces the number of distinct backplane SKUs you need to stock when managing mixed-drive SR670 V2 deployments.
• 1x8 bay configuration: Eight bays in a single module. In 2.5-inch density terms, that's a meaningful chunk of the SR670 V2's total drive capacity in one replaceable assembly.
• 10 lb shipping weight: Heavier than a bare PCB backplane — confirm whether this is the module-with-cage assembly or a standalone board before comparing it to other SR670 V2 backplane options.

Deployment Considerations:

• The SR670 V2 supports multiple backplane configurations; the 4XB7A69396 is one of several options. Match the backplane to your chassis order code and HBA before purchasing — an incorrect backplane is not plug-compatible even within the same server family.
• Evidence for this SKU is limited to distribution feed attributes. Verify NVMe bifurcation requirements and RAID controller compatibility directly against Lenovo's SR670 V2 configuration guide before committing to a drive mix.

Best fit for SR670 V2 deployments where the storage team needs flexibility to mix NVMe, SAS, and SATA within the same bay group — particularly video surveillance NVR builds or AI inference nodes where tiered storage (fast NVMe for index, SAS/SATA for retention) is part of the architecture.
