Eco Migration Algorithms of Processes with Virtual Machines in a Server Cluster

Abstract

It is critical to reduce the electric energy consumption of servers in a cluster. In this paper, we discuss a migration approach to reducing the electric energy consumption where a virtual machine with application processes migrates to a more energy-efficient server. We newly propose an ISEAM2 algorithm to select a pair of a virtual machine on a host server to perform a process issued by an application and a guest server to which the virtual machine migrates so that the electric energy consumption of the host and guest servers can be minimized. In the evaluation, we show the total electric energy consumption and active time of the servers and the average execution time of processes can be reduced in the ISEAM2 algorithm.
