In response to the trend of server development such as cloud computing, virtualization, centralization and high density, the modular data center adopts a modular design concept to minimize the coupling of infrastructure to the server room environment. It integrates subsystems such as power supply and distribution, cooling, cabinets, airflow containment, integrated cabling, and dynamic loop monitoring to improve the overall operational efficiency of the data center and achieve rapid deployment, elastic expansion, and green energy saving.
