Abstract

In order to realize digital ecosystems, the total electric power consumption of servers to perform application processes has to be reduced in information systems. Applications are classified into three types, computation, communication, and storage based types. In the computation and communication types of applications, CPU and communication resources of computers are mainly consumed, respectively. In this paper, we measure how much electric power of a whole computer is consumed to perform application processes. In the storage types of applications, the electric power is consumed to read and write files in to storage drives like hard disk drive (HDD). Then, we discuss a power consumption model of a computer to perform storage application processes by abstracting most factors dominating the power consumption from the experimental results. Here, the power consumption rate of a computer is maximum if at least one process is performed. Otherwise, the power consumption rate is minimum. This is a simple power consumption model.
