Research on Availability of Data Center UPS Power Supply System

摘要

According to the requirements of national standard for data center infrastructure, the typical case study is used to analyze the architecture, advantages and disadvantages of the UPS dual-bus 2N redundant power supply system widely used in large and medium-sized data centers and establish the power supply system availability model to calculate its availability in this paper, so as to analyze the factors affecting the reliability of the data center and the development history of the data center power supply system, and verify the availability of the revised National standard A-level data center "One way (N+1) UPS and one way mains" double bus redundant power supply in GB50174-2017 data center design specification, and analyze its advantages in usability and energy efficiency, investment, and application development prospects.
