Energy efficient distributed systems for storage-based applications

Abstract

The electric power consumption of servers has to be reduced in information systems. There are computation (CP), communication (CM), and storage (ST) types of applications. In CP and CM applications, CPU and communication resources are mainly consumed, respectively. In this paper, we consider ST applications where storage drives are manipulated on a server. First, we measure the power consumption of a server to perform types of ST application processes; C, R, and W processes which just compute, read, and write, respectively. Then, we discuss a power consumption model of a server by abstracting most factors dominating the power consumption of a server from the experimental results. Here, the power consumption of a server is maximum if at least one process is performed. The maximum power consumption depends on types of concurrent processes. © 2012 Springer Science+Business Media B.V.
