Product Overview

AI-generated summary

If you’ve got a supported Lenovo ThinkSystem server (SR250 V3/SR630 V3/SR650 V3 or ST250 V3) and you’re looking for a simple, cost-effective way to add controller-level RAID behavior, the ThinkSystem B540i-2i is a pretty sensible buy. It’s aimed at people who want reliability features like RAID 1 without getting sucked into higher-end, more expensive storage stacks. For small deployments, virtualisation hosts with modest storage needs, or “we need redundancy but can’t justify premium kit” setups, it can be good value at £346.10 ex-VAT—especially because you’re paying for an ecosystem piece that’s designed to work neatly with those specific Lenovo platforms.

That said, I wouldn’t buy it on the basis of “SSD performance” alone. With only two channels, you’re constraining how much you can do in parallel, and you’re not buying into the sort of heavy-duty controller capabilities you’d expect for larger scale-out storage designs. Also, since this is a RAID controller for specific Lenovo systems, make sure you’re confident about compatibility and your intended drive setup before ordering—nothing is worse than paying for a part that technically exists but doesn’t match your exact server configuration. If your goal is multi-drive throughput, big resilience, or flexible expansion, this is likely the wrong class of controller; if your goal is straightforward RAID for a couple of SSDs in a supported Lenovo box, it’s a solid, pragmatic choice.
