In a traditional data center, air conditioning is needed to cool the equipment because it generates a lot of heat, otherwise the servers and other equipment will automatically shut down because of the high temperature. In order to improve the cooling efficiency of air conditioners, designers invented the under-ventilation method, which is to let the cold air from air conditioners blow out from inside the raised floor all the way to the bottom of the IT rack. Then through the floor openings, the cold airflow drilled out of the floor to the front of the server. The fan inside the server "sucks" the cold airflow into the server to dissipate heat, and then exhausts the hot airflow from behind the server. This is the earliest form of cooling, "under-ventilated air conditioning + raised floor".
Later, in order to further improve the utilization of cold airflow and reduce the electricity costs of air conditioning. Some people sealed the cabinet and the channel in front of the cabinet, so that the cold airflow only flows inside the channel, and does not dissipate to other areas of the server room. The benefits of this in addition to more energy efficient, but also in the closed channel inside the formation of a "cold pool", the cold air can be more evenly distributed, will not make some areas because of the lack of cold airflow and affect the work of the server.
Later, some users put UPS, batteries and other power supply and backup equipment into the closed channel, so that they can supply power to the equipment nearby, forming the so-called "distributed power supply" system. After continuous improvement, the final micro-module was born, a micro-module almost contains a complete power supply, cooling, power backup, fire, monitoring systems, can be seen as a complete small room.
At the same time, people also found that this structure can be flexibly configured according to the scale of business, can be prefabricated in advance in the factory, on-site installation to reduce the workload and installation time, but also more energy efficient, reducing the cost of electricity.
After 2010, engineers from many Internet companies began designing different styles of micro-modules according to their business needs. Equipment manufacturers around the world quickly followed suit, whether they were IT equipment manufacturers such as servers or infrastructure manufacturers such as UPS and air conditioners, they all launched their own micro-module solutions. With everyone's promotion, micromodules are also gradually accepted by users from various industries, turning into a mainstream data center construction method.
According to ICT Research report, in 2018, the domestic modular data center market size is 5.114 billion yuan, and the market size is expected to be close to 9 billion yuan in 2023, with a compound annual growth rate of 11%.
