摘　　要：首先介绍了当前存储应用的新特性,认为以服务器为中心的DAS访问模式越来越难以满足现代存储应用的需求,解决问题的关键是将访问模式从以服务器为中心转化为以数据和网络为中心,这推动存储与计算的分离。接着介绍了存储与计算的差异和目前存储资源与计算资源分离的可能性、必要性,以及分离方式和分离后的模式等。认为传统的DAS存储模式已经开始衰落,而新的以NAS/SAN为代表的网络存储系统已经开始迅速增长;NAS和SAN并非相互竞争,而是相互补充。只有将二者融合,才能够将各自的优势充分发挥出来。This thesis first introduced the new features of storage application, and pointed out that DAS did not meet storage demand any more. The solution was change the mode of server-centered to data and network as the core, which drove the se-paration of storage and computing. The thesis then focused on difference between storage and compu-ting, feasibility and necessity of their separation, how to separate and mode after separation. New networked storage system, such as NAS/SAN, began to increase rapidly. The advantages of NAS/SAN take effect as the convergence of them.
