Lenovo ThinkSystem SR630 V3 — Full Technical Specifications
The SR630 V3 is the current thin two-socket ThinkSystem, and Lenovo's most widely specified rack machine of the generation. What it brings over the model before it is memory capacity, tri-mode storage and liquid cooling as a supported option, without changing how it racks or is managed.
The page covers a new build to order as well as refurbished units.

Full Specifications
The cooling row is the one to read first on this V3, because it offers both a closed-loop arrangement and direct water, and either turns the purchase into a conversation about the room. Processors at the top of the range in this height effectively require one of them. After that, the drive row: conventional front bays, rear positions, internal boot devices and a compact fast format are all offered, and the combination is set at build. The memory row's higher figure depends on persistent modules and should not be read as the ordinary ceiling. Expansion at both front and rear is what keeps this machine flexible despite its height.
