Lenovo ThinkSystem M.2 NVMe 2-Bay RAID Enablement Kit for SR645, SR665, SR860 V2

You need NVMe speed on your Lenovo server and you need it with redundancy. This kit slots into the SR645, SR665, or SR860 V2 and gives you two M.2 NVMe bays behind a Marvell 88NR2241 RAID controller. One drive? You get single-drive RAID-0. Two drives? You can run 2-drive RAID-0, 2-drive RAID-1, or split them into two independent single-drive arrays. Handles 2242 through 22110 form factors, so you're not locked to one stick size. PCIe 3.0 x2 to the host, x1 per drive. Manage it through UEFI or your OS tools, monitor temps and events over I2C, push firmware updates through Lenovo's own tooling. No guesswork, no third-party controller drama
