1. A system for responding to file system requests received from a network having file IDs comprising V, a volume identifier specifying the file system being accessed, and R, an integer, specifying the file within the file system being accessed comprising:

  • a file server comprising;

    D disk elements in which files are stored, where D is greater than or equal to 1 and is an integer;

    a switching fabric connected to the D disk elements to route requests to a corresponding disk element; and

    N network elements connected to the switching fabric, each network element having a mapping function that for every value of V, specifies one or more elements from the set D that store the data specified by volume V, where N is greater than or equal to 1 and is an integer and N+D is greater than or equal to 3, which receives the requests and causes the switching fabric to route the requests by their file ID according to the mapping function.
