언제부터인가 주위는 모두 “녹색” 물결로 뒤덥혀 버렸다. 그 중에서도 IT의 존재는 녹색 물결에 휩싸여 새로운 판로를 모색하고 있다. 데이터센터 역시 그 문제점은 수 년 전부터 대두되어 왔고, 정책적으로 혹은 업계 자체적으로 데이터센터의 문제점을 해결하고자 많은 솔루션을 내고 있는 실정이다. 그린 데이터센터를 위한 견해는 먼저 비 IT 영역으로 공조, 항온/항습 시설, 전력 배전 시설 등의 관점에서 접근하는 견해가 있고 IT 영역으로 서버 자체에 대한 관점에서 접근하는 견해가 있다. 본 고에서는 데이터센터 내에서 IT 영역에 대한 전력 관리를 위하여 해야 될 역할에 대하여 언급하고자 한다. 특히 데이터센터 내 서버 자체의 전력 절감을 위한 방법에 대하여 논하고, 앞선 업체들 특히 IBM, Google, SUN 등의 동향으로부터 그린 데이터센터를 위한 방향을 모색해 보기로 한다.
