1. A system for implementing distributed Redundant Array of Independent Disks (RAID), comprising: a plurality of data bank computers, each data bank coupled to each of one or more hosts and each of the other plurality of data banks, each data bank including: a processor; a data store; a high speed memory; a computer readable medium comprising first instructions for a distributed RAID application, the first instructions executable to: receive a command corresponding to a first segment of a volume from a first host of the one or more hosts, wherein the volume and redundancy data corresponding to a RAID level implemented in conjunction with the volume are stored on each of the plurality of data banks according to a data bank order where the data bank order is a permutation of the plurality of data banks, such that for each segment of the volume a corresponding redundancy segment comprising the redundancy data associated with that segment does not reside on the same data bank as the segment; determine if the command is a write command and if the command is a write command storing the write command in a write cache on the high speed memory; determine a first data bank of the plurality of data banks, wherein the first data bank corresponds to the first segment; and if the first data bank is the data bank which received the command, execute the command with respect to the first segment and if not, forward the command to the first data bank.
