Lenovo 4XB7A69397 SR670 V2 3.5 SATA/SAS/NVME1X4-BAY

Lenovo 4XB7A69397 SR670 V2 3.5" 4-Bay SAS/SATA/NVMe Storage Expansion Kit

Overview

The Lenovo 4XB7A69397 is a 3.5-inch, 4-bay hot-swap storage expansion kit designed specifically for the ThinkSystem SR670 V2 server platform. If you are configuring an SR670 V2 for high-capacity workloads — dense NVR storage, security video archives, or data-intensive surveillance back-end infrastructure — this kit extends your drive bay count using the server's native SAS, SATA, and NVMe interfaces. At 10 lb, this is a purpose-built mechanical assembly, not a generic aftermarket bracket. Using genuine Lenovo Lenovo server components ensures firmware compatibility and preserves warranty coverage on the host platform.

Key Features

• Dual-protocol SAS and SATA support: The 4XB7A69397 accommodates both SAS and SATA 3.5-inch drives in the same bay cluster — useful when mixing enterprise SAS HDDs (higher sustained throughput, dual-port failover) with higher-capacity SATA drives for tiered or archive storage. You are not locked into a single drive generation.
• NVMe compatibility: Beyond spinning media, the bay configuration supports NVMe — relevant if the SR670 V2 deployment calls for fast-tier storage alongside capacity-tier drives, such as a write cache or index volume in a multi-camera NVR build on network video recorders.
• 4-bay expansion footprint: A single 4-bay increment fits precisely into validated SR670 V2 server storage configurations without requiring a full chassis redesign, keeping the upgrade surgical and reversible.
• Factory-genuine fit and finish: Weighing 10 lb, this is a machined assembly with drive backplane, not a sheet-metal bracket. Genuine parts avoid the tolerance mismatches that aftermarket alternatives introduce — important in environments where vibration from adjacent drives matters for long-term reliability.

Integration and Compatibility

The 4XB7A69397 is validated for the Lenovo ThinkSystem SR670 V2 server. Confirm your SR670 V2 configuration number and available bay slots before ordering — Lenovo's ServerProven database documents exactly which storage options are validated per chassis build. This kit integrates with Lenovo XClarity Administrator for unified hardware inventory and firmware management across your server management stack. Drive compatibility depends on the installed HBA or RAID controller; verify controller support for the specific SAS, SATA, or NVMe drives you intend to populate.

Frequently Asked Questions

Q: What server platform is the Lenovo 4XB7A69397 designed for?

A: The 4XB7A69397 is designed for the Lenovo ThinkSystem SR670 V2 server. It is not a universal fit — always verify against your specific SR670 V2 configuration before ordering.

Q: What drive interfaces does the 4XB7A69397 support?

A: The kit supports SAS, SATA, and NVMe 3.5-inch drives, giving you flexibility to mix drive types based on performance and capacity requirements.

Q: How many drive bays does this kit add?

A: The 4XB7A69397 provides a 4-bay expansion using 3.5-inch form factor drives.

Q: How much does the 4XB7A69397 weigh?

A: The assembly weighs 10 lb, reflecting its full backplane-and-cage construction rather than a simple bracket.

Q: Is this kit compatible with Lenovo XClarity management tools?

A: As a genuine Lenovo SR670 V2 component, the 4XB7A69397 integrates within the XClarity Administrator hardware inventory framework. Specific feature support depends on firmware revision and controller configuration.

Eden Phillips

The 4XB7A69397 is a straightforward but important spec decision for SR670 V2 builds: the SAS/SATA/NVMe-capable 3.5-inch 4-bay assembly lets you preserve drive-type flexibility rather than committing to a single protocol at configuration time. If you are sizing storage for a high-channel NVR back-end or a security video archive, that protocol optionality is worth having up front — retrofitting bay types after the server is racked is more disruptive than getting the cage right during initial build.

Technical Highlights:

• SAS + SATA + NVMe in one bay cluster: Mixing SAS (dual-port, higher IOPS) with SATA (larger capacity per dollar) in the same 4-bay group supports tiered storage layouts without a separate expansion chassis.
• 3.5-inch form factor: 3.5-inch drives deliver the highest capacity per spindle for HDD-based archival tiers — the right call when retention windows exceed 30 days across many camera channels and cost-per-TB is the dominant constraint.
• 10 lb assembly weight: The 10 lb weight signals a full backplane-integrated cage, not a passive bracket — drive power and signal routing is handled by the assembly itself, reducing field wiring errors during drive population.

Deployment Considerations:

• Confirm available bay slots and HBA/RAID controller firmware support before ordering — the SR670 V2 has multiple storage configuration variants and not all bay positions are interchangeable.
• NVMe drives require an NVMe-capable controller or direct CPU PCIe attachment; the bay supports NVMe physically, but throughput depends entirely on the controller side of the equation — do not assume NVMe performance without verifying the controller SKU in your build.

This kit is the right call for SR670 V2 deployments where the storage mix is not yet finalized at order time — security integrators building out multi-terabyte NVR back-ends who need to defer the SAS-vs-SATA-vs-NVMe decision until drive pricing and retention requirements are confirmed will find the 4XB7A69397's protocol flexibility directly useful.
