대부분의 데이터 센터는 평균적으로 총 자원의 20% ~ 30%만이 사용되고 있고 50% 미만의 전력 효율을 갖고 있다. 유연한 전력 관리 정책을 적용하면 데이터 센터의 전력 효율을 높일 수 있고 이를 위해서는 동적 부하에 따른 정확한 전력 소비량을 예측 가능해야 한다. 하지만 부하에 따른 서버의 전력 소비량 예측은 시스템 구축비용 및 컴퓨팅 비용이 매우 높은 편이다. 본 논문에서는 기존의 시스템 정보를 이용한 서버 전력 측정 방법을 소개하고 간편한 구축과 저렴한 컴퓨팅 비용으로 시스템 부하에 따른 전력 소비량을 예측할 수 있는 방법을 제시한다. 시스템 부하를 분류하고 부하 별 전력 모델을 도출하여 적용함으로써 보다 정확한 예측 방법을 제안하였다. 또한, 실제 서버 환경을 구축하여 평가를 진행하였고 제안한 방법의 타당성을 증명하였다.
