Abstract: A kind of highly reliable fault-tolerant server with excellent performance which combines COTS technique and traditional fault tolerance technique is designed and realized in this paper. The server is based on the state-of-the-art hardware and software. It is open and adopts transparent fault tolerance with low cost and strong scalability. The paper highlights key design principle and roll-forward fault recovery technique of the server.

Key words: Fault-tolerant server, COTS, Reliability, Roll-forward fault recovery
