摘要：A system for responding to file system requests having file IDs comprising V, a

volume identifier specifying the file system being accessed, and R, an integer, specifyingthe file within the file system being accessed. The system includes D disk elements inwhich files are stored, where D is greater than or equal to 1 and is an integer. The systemincludes a switching fabric connected to the D disk elements to route requests to acorresponding disk element. The system includes N network elements connected to theswitching fabric. Each network element has 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 equalto 3, which receives the requests and causes the switching fabric to route the requests bytheir file ID according to the mapping function. A method for responding to file systemrequests. The method includes the steps of receiving file system requests having file IDscomprising V, a volume identifier specifying the file system being accessed, and R, aninteger, specifying the file within the file system being accessed at network elements.Each network element has a mapping function that for every value of V, specifies one ormore elements from the set D that store the data specified by volume V. Then there isthe step of routing the requests to a switching fabric connected to the network elementsbased on the file system request's ID according to the mapping function to diskelements connected to the switching fabric.
