Unlike conventional Massively Multiplayer On-line Role Playing Games (MMORPG) that confine players to a server with only a few hundred other players, WISH defines the new category of on-line gaming called Ultra Massive Multiplayer On-line Role Playing Games (UMMORPG). A highly-scalable BladeRack server cluster infrastructure enables WISH to support tens of thousands of simultaneous players in a single gaming environment.

The RackSaver BladeRack selected by Mutable Realms contains 176 Intel Xeon processors in one industry standard-sized rack with a combined processing power of nearly one teraflop. The BladeRack also contains nearly 176GB of high-speed memory and 5.2TB of storage capacity.
