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 virtual machines with application processes migrate to more energy-efficient servers. In the SEAM algorithm previously proposed, a host server to perform a process and to migrate a virtual machine is selected whose expected electric energy consumption is minimum. In this paper, the SEAM algorithm is improved where a host server is selected with minimum expected electric energy consumed by not only the host server but also the other servers. We show the total electric energy consumption of the servers can be reduced in the improved SEAM (ISEAM) algorithm compared with non-migration algorithms and the SGEA algorithm in the evaluation.
