With the rapid development of the Internet, enterprise informatization construction is becoming more and more important, and the rationality of data center network design has become the top priority of enterprise informatization construction. This paper mainly analyzes the high-availability design of the data center network and the optimization of the information technology architecture. When designing a data center network, it is necessary to analyze and plan the network architecture in combination with the specific conditions of the enterprise data center, so as to maximize the reliability of the network system, thereby improving the availability of the data center network. The optimization of information technology architecture also needs to comprehensively consider various factors such as system architecture, equipment functions, performance, and cost, so as to establish an information technology architecture suitable for its own development. Experimental results show that the bandwidth of the optimized data center network can reach 11.5TB/s.
