Abstract
An apparatus for increased data access in a network includes a file/object server computer having a permanent storage memory, a cache verifying computer operably connected to the file/object server computer in a manner to form a network for rapidly transferring data, the cache verifying computer having an operating system, a first memory and a processor capable of performing an operation on data stored in the permanent storage memory of the file/object server computer to produce a signature of the data characteristic of one of a file, an object and a directory, a remote client computer having an operating system, a first memory, a cache memory and a processor capable of performing an operation on data stored in the cache memory to produce a signature of the data, a communication server operably connected to the remote client computer to the cache verifying computer and the file/object server computer and comparators operably associated with the cache verifying computer and remote client computer for comparing the signatures of data with one another to determine whether the signature of data of the remote client is valid.
