Abstract
A method, system and program are disclosed for accelerating data storage in a cache appliance that transparently monitors NFS and CIFS traffic between clients and NAS subsystems and caches files in a cache memory by using a dual hash technique to rapidly store and/or retrieve connection state information for cached connections in a plurality of index tables that are indexed by hashing network protocol address information with a pair of irreducible CRC hash algorithms to obtain an index to the memory location of the connection state information.
