Title: The Extended Transmission Power Consumption Model for Communication-Based Applications
Abstract: In information systems, a client first selects a server in a cluster of servers and issues a request to the server. The request is performed as a process in the server. In this paper, we consider a communication process which mainly consumes communication resource. It is critical to discuss how to select a server for each request from clients in order to not only achieve performance objectives but also reduce the total power consumption of a system. In order to realize the server selection algorithm, it is necessary to make clear the power consumption model of a server to perform processes. The transmission power consumption (TPC) model of a server is proposed to perform transmission processes in our previous studies. In the TPC model, the electric power consumption of cooling devices is assumed to be constant. Cooling devices like fans consume the electric power in addition to other devices like CPU and memory in a server. The rotation speed of a fan is changed in servers according to the temperature of a server. Thus, the total power consumption of a server depends on not only computation and communication devices but also cooling devices. In this paper, we propose the extended transmission power consumption (ETPC) model to take into account the power consumption of cooling devices. We validate the ETPC model by measuring the power consumption and transmission time of a server.
