Pittsburgh, Pennsylvania-based Interstream Inc has a new implementation of its eNFS Network File System software which resides on the client and is claimed to offer continued access to Network File System data during interruptions due to server failures or overloading. The e/NFS/PFS program sits between the application and TCP/IP communications software monitoring Network File System requests and Remote Procedure call responses during network and client-server operations, activating whenever intervention is required because of a unresponsive Network File System server; e/NFS/PFS includes Interstream’s eNFS/Cache client NFS disk caching system and costs $500 per Network File System client. Upgrades from e/NFS/Cache are also available.
