Web服务器集群中的文件优化分配

Optimizing Allocation of Files in Web Server Cluster

在现代的网络研究中,高性能集群服务器越来越显示其重要的作用,而在集群中分布地存储着大量的文件。文章在研究了集群服务器性能和文件的访问概率及连接数的基础上,推算出了文件在服务器上的拷贝数,并根据文件间的相关性将文件集合成文件簇,最后提出了一种基于文件簇的文件优化分配策略,提高了服务器的效率和稳定性。

In the research of modern network,high ability serv er cluster has taken more and more important effect,and there are a large amount of files in the server cluster.After studying the capability of the server cluster and the visited probability and the connection of these files,the paper deduces the number of file's copies in the server.And on the basis of the correlation of the files,it divides the files into the file cluster.Finally the paper introduces a strategy of optimizing files allocation basing on the file cluster,which improves the efficiency and the stability of the server cluster.
