Lenovo 4X97A91725 ThinkSystem RAID SD550 V3 Kit for Dual-CPU Configurations

Overview

The Lenovo 4X97A91725 is a RAID enablement kit designed specifically for ThinkSystem SD550 V3 servers deployed in two-CPU configurations. If you're expanding an SD550 V3 node to a dual-processor build and need to add or restore RAID capability, this kit provides the hardware components required to support that configuration — addressing the common gap where a single-CPU RAID setup doesn't carry over directly to a 2-CPU build without the correct supplemental hardware.

Compatibility

Designed for the Lenovo ThinkSystem SD550 V3 platform in dual-CPU (2 CPU) configurations specifically. The SD550 V3 is a high-density server node used in ThinkSystem D8 Flexible Chassis deployments — confirm your chassis and node generation before ordering, as RAID kit compatibility is generation-specific and not interchangeable with SD550 (V1/V2) or other SD-series nodes. This kit is listed under server components and upgrade kits and is not compatible with single-CPU SD550 V3 configurations, which require a different part number. Verify your current CPU population and RAID controller model against Lenovo's SD550 V3 configuration guide before placing an order — mismatched kits will not install correctly.
