Lenovo 4M17A60519 ThinkSystem SE350 M.2 Mirroring Enablement Kit
Overview
The Lenovo 4M17A60519 is an M.2 Mirroring Enablement Kit designed for the ThinkSystem SE350 edge server. It adds a PCIe 2.0 x2 host interface that enables M.2 drive mirroring — giving the SE350's OS or hypervisor volume hardware-level redundancy without relying on software RAID. In edge deployments where the SE350 runs surveillance workloads, access control middleware, or lightweight VMS at a remote site, a mirrored boot/OS drive protects against single-drive failure and reduces unplanned downtime in locations where on-site IT support is not available.
Compatibility
Designed specifically for the Lenovo ThinkSystem SE350 edge server platform. The PCIe 2.0 x2 host interface slots into the SE350's internal expansion architecture. Confirm your SE350 chassis revision and firmware level against Lenovo's SE350 options compatibility matrix before ordering — M.2 slot availability varies by base configuration.
Installation Notes
The kit ships at a compact 0.80 x 0.10 x 0.50 in and weighs 2.00 lb. Internal PCIe adapter installation requires powering down the SE350 and following standard ESD precautions. M.2 drives are not included — source NVMe or SATA M.2 modules separately per the SE350 compatibility list. Verify that the SE350's system firmware is at a revision that supports mirroring enablement prior to seating the adapter.
