Websites and even servers are becoming more and more popular. This infection is usually used to intercept communication, black hat SEO, leeching downloads, and so on. In most cases, such malware is composed of relatively simple PHP scripts. But in the last two years, many more c
More and more IT organizations tend to use server virtualization to transform the data center into a "service-centric" Resource Sharing pool, A smart network is used to dynamically merge, layer, configure, and access these resources. Standard Server resource virtualization can dynamically increase the performance level and reduce the total cost of ownership (TCO). At the same time, through virtualization, IT organizations can quickly deploy and expand resources as needed, to meet business and ap
Energy-saving technology for data center servers
Every time you walk into the data center room, you can see that the vast racks are filled with servers. In a data center, the number of servers determines the service processing capability of the data center. In medium and large data centers, thousands of servers are us
