PATHWORKS for VMS File Server

The PATHWORKS for VMS file server integrates industry-standard personal computers with VAX VMS systems over a communications network. It implements Microsoft's server message block (SMB) core protocol, which provides resource sharing using a client-server model. The server provides transparent network access to VAX VMS FILES-11 files from a PC's native operating system. The architecture supports multiple transports to ensure interoperability among all PCs connected on an open network. Due to the performance constraints of many PC applications, data caching and a variety of other algorithms and heuristics were employed to decrease request response time. The file server also implements a security model to provide VMS security mechanisms to PC users.
