RSI, conceptually, blows server components – CPU, GPU, storage, memory, network – across separate racks, enabling each to be sized and upgraded in full rack boxes, connected by high-capacity/low latency, PCIe links. Layer on top of that virtual server software, so virtual servers can be constructed from pieces of the rack-scale components, and you have a game-changing config that makes enterprise infrastructure competitive with cloud services.
