Existing network file system protocols can be accelerated by allowing clients to access data directly across a SAN, when the existing network file system protocol has a component that controls the validity of a client cache. SAN access information can be sent from the server to the client as an attribute of the file, and the validity of that SAN access information can be guaranteed or invalidated in the same way that the protocol guarantees or invalidates the existing client data cache.
