Interstream Inc, Pittsburgh, Pennsylvania has introduced eNFS/PFS, the company’s new eNFS implementation designed to provide continued access to Network File System data during Network File System server failures or overloads. Built on top of Interstream’s eNFS/Cache product, it resides directly on the client workstation positioned between the user’s application environment and the client’s TCP/IP software. The system can either access cache data or allow the client’s disk to act as a personal Network File System server. The product, handy for portable clients, results from a survey of Network File System users about their biggest networking concerns. Price is $500 per client.
