데이터 센터의 수가 증가하고 대형화됨에 따라 데이터 센터에서의 전력 소비는 급격하게 증가하고 있으며, 이를 해결하기 위해서 전력변환효율을 증대시키거나 소비 전력이 적은 서버를 개발하는 등의 접근이 이루어지고 있다. 본 논문에서는 전력관리를 통해서 소비전력을 줄이기 위한 그린전력관리시스템을 제안한다. 전형적인 서버의 경우에는 Idle 상태에서는 사용 중인 소비 전력의 약 60% 정도를 소비하고, 데이터 센터에서는 서버의 응답시간을 줄이기 위해서 약 5~20%을 효율로 서버를 운용하고 있으며, 평균적으로 약 10%의 서버가 사용되지 않고 있다. 이러한 이유로 동적으로 서버를 관리하여 데이터센터에서 낭비되는 서버의 소비 전력을 줄이고자 한다.
