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 perfect hashing memory index technique to rapidly detect predetermined patterns in received packet payloads and retrieve matching patterns from memory by generating a data structure pointer and index offset to directly address the pattern in the datagram memory, thereby accelerating evaluation of the packet with the matching pattern by the host processor.
