A data center is an IT equipment facility that gathers a large number of servers, storage devices, network equipment, and supporting UPS, precision air conditioning, and other equipment. It is a service platform that enables centralized processing, storage, transmission, exchange, and management of data information. From a physical perspective, data centers are mainly composed of three parts: IT equipment, power distribution systems, and air conditioning systems. IT equipment is used for data processing (servers), data storage (storage devices), and communication (network devices), and is the core part of implementing data center functions; The power distribution system and air conditioning system are the guarantee for the normal operation of IT equipment systems. The power distribution system is used to provide stable power supply, achieve DC to AC conversion, and ensure reliable and high-quality power supply for IT equipment; The air conditioning system ensures that IT equipment operates at normal temperature and humidity.
