In recent years, with the continuous development of human resources and social security, the daily management and maintenance work of data center is increasingly heavy, while there are some disadvantages including the long construction period of traditional data center, difficult capacity expansion, high energy consumption, low management efficiency, and so on. To improve the security and efficiency of data center, the design of integrated data center is introduced, which makes cabinet system, power supply and distribution system, cooling system, integrated wiring system and other modules integrate effectively, and uses intelligent management mechanism to achieve centralized management and monitoring. It can provide the strong guarantee for the security and stable operation of data center.
