Classification and performance requirements: The classification data center should be divided into three levels: A, B, and C. When designing, the level of ownership should be determined based on the nature of the data center's use, the degree of economic or social losses or impacts caused by data loss or network interruption&Nbsp; Data centers that meet one of the following conditions should be classified as Grade A: 1. Interruption of electronic information system operation will cause significant economic losses; 2. Interruption of electronic information system operation will cause serious disorder in public places. Data centers that meet one of the following conditions should be classified as B-level. Interruption of electronic information system operation will cause significant economic losses; Interruption of electronic information system operation will cause disorder in public places. Data centers that do not belong to Class A or B should be classified as Class C. The various components of the data center infrastructure should be designed according to the same level of technical requirements, and can also be designed according to different levels of technical requirements. When each component is designed according to different levels, the level of the data center is determined based on the lowest level part. Performance requirements: The infrastructure of the A-level data center should be configured as a fault-tolerant system. During the operation of the electronic information system, the infrastructure should still ensure the normal operation of the electronic information system after an accident or during single system equipment maintenance or repair. When the A-level data center meets the following requirements, the power supply of the electronic information equipment can be achieved by combining an uninterrupted power supply system and a mains power supply system. When maintaining equipment or circuits, ensure the normal operation of electronic information equipment; The quality of the power supply directly supplied by the 2 mains power supply should meet the requirements for the normal operation of electronic information equipment; The power factor at the 3 city power access points should meet the requirements of the local power supply department:. 4 The diesel generator system should be able to withstand the impact of capacitive loads; The harmonic current component (root mean square value) injected into the public power grid should not exceed the allowable harmonic current value specified in the current national standard "Power Quality - Harmonics in Public Power Grids" GB/T14549
