Lenovo ThinkSystem SR630 V2 — Full Technical Specifications

Note the slot row, which puts expansion positions at the front of the chassis as well as the rear — that is what makes accelerators or a front-mounted controller workable in this height, and it is a chassis configuration rather than an option. The drive row offers conventional, large-format and a compact fast format, and this V2 is where that third choice first becomes practical; picking it commits the machine to a drive estate of its own. The accelerator row is limited to low-power single-width cards, which is honest for the height. Power runs to high ratings because two fully specified processors here need them.
