%X In order to improve the throughput, response speed and scalability of Web servers efficiently, many famous Web sites have thrown away single servers and turned to Web server clusters. Web server clusters with different distribution modes of data copy have different data availability levels. After discussing many data copy distribution modes, an optimized data copy distribution is proved in this paper.
