(A very important part of the construction of the data core infrastructure is the construction of the computer room. Computer room engineering not only integrates construction, electrical, installation, network and other professional technologies, but also requires rich experience in project implementation and management. The quality of the design and construction of the computer room is directly related to whether the computer system in the computer room can run stably and reliably, and whether it can ensure the smooth flow of various information communications. The computer room must not only ensure the safe and reliable normal operation of the equipment in the computer room, prolong the service life of the computer system, but also create a comfortable office environment for the system administrator, which can meet the requirements of the equipment in the computer room for temperature, humidity, cleanliness, electromagnetic field strength, noise interference, Requirements for safety and security, leakage prevention, power quality, vibration, lightning protection and grounding, etc. Therefore, a qualified modern computer room should be a safe, reliable, comfortable, practical, energy-efficient and expandable computer room.)
