Abstract

Since most education organizations such as Universities have a plenty of PCs, much electric power can be wasted if their power states are not managed properly. This paper introduces the RPM(Remote Power Management) software system implemented to reduce a waste of PC power in Universities. The System manager can monitor power state of all PCs in a University and turn off PCs or change power states of PCs to low power states. The RPM consists of three software modules. First, Power Controller, which is installed in each user PC, saves the power by changing low power state by utilizing low power algorithm proposed in this paper. Also it reports power state of its PC to Power Server on the state changed. Second, Power Server module gathers power state information of all PCs, stores them in a DB, and sends all or some parts of the information to Power Viewer whenever the manager asks. The manager can turn off or change a certain PC to low power state. We evaluated the performance of power saving for the RPM and the result showed achievement of 40% power saving.

대학 등의 교육 기관은 대량의 PC들을 갖추고 있으므로, 이들의 전원 상태를 관리하지 않으면 많은 전력을 낭비할 수 있다. 본 논문은 대학 내 PC들에 대해, 원격으로 PC 들의 상태를 모니터링하여 PC의 전원 상태를 확인하거나, PC 전원을 끌 수 있는 전원 관리 시스템(Remote Power Manager, RPM)을 개발한 사례를 소개한다. RPM은 PC에서 독립적으로 전원을 관리하는 Power Controller 소프트웨어 모듈과, 전체 PC의 전원 상태를 관리하는 Power Server, 그리고 관리자가 각 PC의 전원 상태를 보거나 끌 수 있는 Power Viewer 소프트웨어 모듈로 구성된다. RPM 시스템을 설치하여 대학 내에서 실험한 결과 40% 정도 에너지를 절약하는 결과를 얻었다.
