Abstract

It is highly in demand to establish a bunker-type underground data center to ensure the safety of national critical data, such as financial information and medical information, and prevent those outflow of national important data. In particular, the security of a data center which is a key national structure has become a social issue due to EMP weapon and earthquakes, but data centers in the nation have not been able to deal with it properly. Therefore, it is necessary to develop an underground data center that is safe from human-induced and natural disasters while reducing power costs by utilizing the benefits of underground spaces such as constant temperature and isolation. In this analysis, the status and trends of data centers around the world were analyzed and based on those trend analyses, the research strategy for underground data center were discussed.

국가의 금융 정보나 의료 정보와 같이 국가 차원에서 안정성을 확보하고 주요하게 다뤄지는 자료는 안전한 보관 및 관리되어야 하므로 이를 위해서는 벙커형 지하 데이터센터를 건설하는 것이 요구된다. 특히 국가 차원의 데이터센터는 지진과 같은 외력에 의해 데이터센터의 기능이 마비되는 것을 방지하는 기능과 이를 충분히 관리할 요건을 갖추어야 할 것이다. 따라서 자연 위협이나 인적 위협에 대한 데이터를 안전하게 보관하고 지하 공간이 갖는 장점을 활용하여 각 국가에서는 지하 데이터센터를 건설하고 있는 추세이다. 본 보고에서는 이러한 세계적인 데이터센터 현황과 동향을 분석하고 우리나라가 진행되어야 할 전략에 대해 검토하였다.
