FAULT TOLERANT NFS SERVER SYSTEM AND MIRRORING PROTOCOL

摘要

A network computer system providing fault tolerant storage and retrieval of data files including a client system (26) connected to a data communication network that may source a first data transfer request to said data communication network for the transfer or retrieval of data. A first server System (12) and a second server system (14), both including media for storage of data files, are connected to the data communication network. Control protocol, established between the first and second server systems, coordinates an asymmetric response by the first and second server systems to a first data transfer request, such that file data transferred by the client is replicated to the first and second storage media and such that file data transferred to the client system is non-replicatively provided to the client system by either the first or second server system.
