latency by half under the same conditions can greatly improve the basic performance and throughput of applications, greatly reducing infrastructure requirements and greatly reducing costs. Case 4: highly intensive device sharing and Convergence As devices in the data center become increasingly intensive, users are using the frontend network to match the backend bandwidth to maximize the utilization of assets. In other words, if InfiniBand can be used

Ubuntu has been widely used on desktops. As a server operating system with a long history, it will also have a place in the field of data centers. In a recent Ubuntu global user survey, nearly 1/3 of respondents were from small companies with fewer than 10 employees, only 28% of people work in the United States (55% in Europe ). Most people mainly use basic functions such as web pages, printing, files, databases, and server backup. Only a small number
