While datacenter operation cost increases with electricity price rise, many researchers study low-power processor based supercomputers to reduce power consumption of datacenters. Reliability of low-power processors for supercomputers can be of concern since the reliability of many low-power processo...

국내 100여개 데이터센터들의 2013년 전력소모량은 얼마인가? | 데이터센터는 서버 및 냉각시설의 운영을 위해 다량의 전력을 소모하는데, 그린피스 조사결과에 따르면 국내 100여개 데이터센터들의 2013년 전력소모량은 약 26억 kWh 로 추산되고 있다.1) 이는 한 달간 1,200만 가구가 사용 가능한 전력수준으로, 데이터센터 수, 전력소비량, 전력가격 및 랙(rack) 단위 발열밀도 또한 증가추세에 있어 운영비 절감을 위해 데이터센터의 효율적인 전력관리가 중요해 지고 있다. | |
데이터센터는 전력량의 대부분은 어디에 소비하는가? | 데이터센터는 전력량의 대부분을 서버의 전력소비 및 컴퓨터 발열로 인한 냉방부하로 소비하고 있다.3,4) 일례로, 한국과학기술정보연구원 (KISTI)의 슈퍼컴퓨팅 센터의 경우 수전용량의 약 59%를 냉방설비에 사용 중이다. | |
데이터센터가 전력량 소비 대부분을 냉방부하로 사용하고 있는 실제 사례는 무엇인가? | 데이터센터는 전력량의 대부분을 서버의 전력소비 및 컴퓨터 발열로 인한 냉방부하로 소비하고 있다.3,4) 일례로, 한국과학기술정보연구원 (KISTI)의 슈퍼컴퓨팅 센터의 경우 수전용량의 약 59%를 냉방설비에 사용 중이다.5)이에 따라 데이터센터의 냉방에너지 소비와 열 부하를 줄이기 위해 서버 및 슈퍼컴퓨터의 에너지 효율이 중요시 되면서, 최근 저전력 프로세서를 사용하여 데이터센터의 소비전력을 줄이려는 시도들이 있다. |
