Lenovo 4XH7A93166 SR635 V3/SR645 V3 7MM RAID Sata/nvme KIT

Lenovo 4XH7A93166 7mm RAID SATA/NVMe Drive Kit

Overview

The Lenovo 4XH7A93166 is a 7mm RAID drive kit designed specifically for the ThinkSystem SR635 V3 and SR645 V3 server platforms. It adds dual-interface storage support — both SATA and NVMe — giving you flexibility to configure RAID arrays using either drive technology without hunting for a separate adapter. If you're provisioning SR635 V3 or SR645 V3 nodes for storage-intensive workloads and need a factory-matched drive kit rather than piecing together third-party components, this is the correct part. The 4XH7A93166 ships from Mexico (country of origin: MX) and is classified under UNSPSC 43211600 (computer storage devices and media).

Compatibility

Verified compatible with the following Lenovo ThinkSystem platforms:

• ThinkSystem SR635 V3 — AMD EPYC-based 1U rack server
• ThinkSystem SR645 V3 — AMD EPYC-based 2U rack server

The kit is platform-specific. Do not assume compatibility with SR630, SR650, or other V2-generation systems — the 7mm drive bay geometry and RAID controller interface on the V3 platforms differ from prior generations. Confirm your server's exact model designation before ordering.

Installation Notes

The kit supports both NVMe and SATA interface connections, which means drive selection matters: installing a SATA drive into an NVMe-only backplane slot (or vice versa) will result in no detection. Verify your SR635 V3 or SR645 V3 backplane configuration against Lenovo's server configuration guide before populating bays. The 7mm drive form factor is thinner than the standard 15mm SAS/SATA hot-swap sled — using non-7mm drives in this kit will cause improper seating and potential airflow issues in the chassis.
