Abstract

A client usually issues a request to one server in a cluster of servers and the server sends a reply to the client. Once the server stops by fault, the client is suspended to wait for a reply. In order to be tolerant of server faults, each request is redundantly performed on multiple servers. Here, the more number of servers a request process is redundantly performed, the more reliable but the more amount of electric energy is consumed. Thus, it is critical to discuss how to realize energy-aware, robust clusters of servers. In this paper, we newly propose the improved redundant power consumption laxity-based (IRPCLB) algorithm where once a process successfully terminates on one server, meaningless redundant processes are not performed on the other servers. We show the total power consumption of servers is reduced in the IRPCLB algorithm.
