Lenovo 4X97A80366 SR670 RAID 940 Upgrade KIT

Lenovo 4X97A80366 SR670 RAID 940 Upgrade Kit

Overview

The Lenovo 4X97A80366 is a RAID 940 Upgrade Kit designed to expand or enable RAID controller functionality on Lenovo ThinkSystem SR670 servers. If your SR670 is running without a dedicated RAID 940 controller — or you're adding storage capacity that exceeds the baseline controller's capacity — this kit provides the hardware components needed to bring that controller online. At 10 lb, this is a substantive hardware assembly, not a software license or bracket: expect physical controller cards and associated hardware that require rack-level installation. UNSPSC code 43202105 classifies this as data storage and management hardware, consistent with a controller upgrade assembly.

Compatibility

Designed specifically for the Lenovo ThinkSystem SR670 server platform. The SR670 is a 2U dual-socket server targeted at AI inference, virtualization, and high-density storage workloads — environments where RAID 940-class performance (NVMe-capable, tri-mode: SAS/SATA/NVMe) directly affects throughput and data protection. Verify your SR670 chassis revision and existing controller slot occupancy before ordering — the SR670 supports multiple RAID configurations and not all bays and slots are equivalent. Confirm with your server's Configuration ID that the RAID 940 controller is not already installed; this kit is an upgrade, not a replacement for a failed unit.

Installation Notes

Installation requires access to the SR670 chassis interior. Given the 10 lb assembly weight, coordinate with your data center team for proper handling during installation. Follow Lenovo's ThinkSystem SR670 Maintenance Manual torque and ESD precautions for controller card seating. Firmware updates to the server's XClarity Controller may be required after installation to recognize the new RAID 940 hardware. Plan a maintenance window — the server must be powered down for physical card installation.
