Cloud computing platforms are the infrastructure of the information society. Reliability, network performance and energy conservation are common issues in industry development. This project has developed a highly available carrier-class cloud platform to provide a credible and stable infrastructure for e-government, big data and other information industries. Facility base.  The  first is reliability. Cloud system failures will face fatal risks for users of service interruption and data loss, with economic losses exceeding one million yuan per minute. Google, Ali, Tencent Cloud, etc. have experienced multiple failures in recent years, and none of the top manufacturers in the industry have been spared. Since the cloud platform code volume exceeds 10 million lines, a single cloud platform cannot achieve 100% SLA; The second is network performance, which directly affects user experience and business revenue. According to the trusted cloud assessment of the Ministry of Industry and Information Technology, the virtual machine network throughput of mainstream cloud platforms (Alibaba Cloud, Microsoft Cloud, etc.) is less than 2Gbps. How to approach the physical server network line speed of 10G is the key to improving cloud performance; the third is green energy conservation. Shanghai's cloud rack demand is increasing by 20% annually, and power distribution indicators are increasing by& lt;10% annually. Green data centers such as Google and Apple are all built in extremely cold and desert areas to save energy by reducing cooling energy consumption. However, due to climatic and geographical conditions, the Yangtze River Delta region has PUE levels above 1.7. The adoption of multi-energy co-supply and high-density servers in the whole cabinet are the mainstream energy-saving solutions. Due to the technical difficulties in multi-parameter coordination in complex large systems such as the cold inertia of refrigeration systems and the rapid response of power generation systems, there is no successful case in the industry of multi-connected supply and stable operation of large-scale data centers.  The  main innovations of this project: 1) Innovatively proposes a two-layer fusion architecture for cloud management control nodes between the operator resource domain and the customer side service domain, realizing interconnection between user premises cloud nodes, edge cloud computing nodes and third-party public clouds through a two-layer dedicated line and DCI network. and unified orchestration management control, the multi-cloud deployment solution based on cloud network integration fundamentally solves the problem of 100% SLA for cloud services; 2) Innovatively developed a software-defined high-performance networking technology based on flow table aggregation algorithm, which greatly improved the performance of cloud platform networks. The connection establishment time for end-to-end communication has been increased from seconds to milliseconds, and the network throughput of 10 Gigabit servers and single virtual machines has been increased from 2Gbps to 9Gbps; 3) For the first time in the industry, long-term reliable operation is achieved based on the triple power supply zoning dynamic balance system. Genetic algorithm optimization is used to achieve multi-parameter balance matching under the case of multiple units cascading, allowing the system to be double-switched in one day, 7.*Achieve carrier-class reliability during 24 hours of operation, with an average annual PUE of 1.27 being the best in East China;4) Developed an innovative high-density modular whole-cabinet server technology based on CoolHat's active precision liquid cooling terminal, adopting dynamic enclosed cooling and cooling channels The design improves the server density and overall power of the entire cabinet. The cabinet power is up to 12.5KW (ordinary rack 5KW), and the power consumption of the single computing node is reduced by approximately 17%. This project published 18 academic papers, obtained 7 authorized invention patents, and 11 national/industry standards.  The results have been widely promoted in the industry, with remarkable economic and social benefits. In 2018, Telecom Government Cloud won the ldquo; Trusted Cloud Industry Cloud Award rdquo; issued by the Ministry of Industry and Information Technology, and has been deployed and applied to gt;50000 computing nodes; the delivery of whole cabinet servers ranks first in the industry and has been successfully applied to Baidu, Ali and other industry giants, helping 27 provincial and municipal governments across the country to big data platforms; the triple power supply data center solution has obtained the UPTIME International Reliable and Sustainable Operation Standard certification, saving more than 50 million yuan in annual electricity bills. From 2016 to 2018, the cumulative added output value of each unit of the project was approximately 1.3 billion yuan, and the added profit was approximately 150 million yuan.
