Development of a Low-cost Server Management System Incorporating a Peer-to-Peer Method for Constructing a High-availability Server System

Abstract

With the growth of the internet use, the reliability of servers that offer various services to clients are becoming an important issue. Power consumption and cost of a server system are also important issues to keep environments and satisfy budgets available for a project. This paper proposes a server management system that is tolerant of trouble that occurs simultaneously in two servers. In addition, the proposed system does not depend on the number of target servers for management. The key ideas in our approach are (1) construction of server groups to realize high reliability, (2) management function to monitor the operation status of the servers, (3) a server function recovery operation using a virtual server to continue internet services in case of server trouble. Experimental results show that our approach ensures high-reliable operation of internet services.
