| 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 scalabilily. The paper highlights key design principle and roll-forward fault recovery technique of the server. |
