Herein, a peer-to-peer (P2P) method server management system that does not require a dedicated management server is proposed as a way to construct a server system with high availability. In the P2P method, each management server uses a file server to share the management files required to manage their target servers and uses virtual server system data to recover server functions after failures. Hence, the P2P method is highly dependent on the file server when managing the server system, and the file server performance
determines the number of target servers that can be managed. With these points in mind, we propose two systems (a synchronous editing method that provides a file-sharing system and an original server method that provides a virtual server startup method) that do not require the use of a file server. We also outline their configurations and performance levels and then discuss solutions to the problems that are likely to occur during the introduction of those systems. Furthermore, we report on the construction of an experimental server system that can operate using both our proposed method and a conventional method, with which the server function recovery times of both methods were measured and compared. The results of our experiments show that, using our proposed method, it is possible to construct a P2P method server management system that does not require a file server, and that the server performance is improved by the improved recovery processing of server functions after failures. Furthermore, customers can receive higher quality services because adopting our proposed method results in an increase in server system availability.
