摘要
网络上的数字信息呈爆炸性增长,SAN(StorageAreaNetwork,存储区域网)越来越多地在企业级存储中得到应用。SAN的虚拟化是存储系统的发展趋势,它在文件系统层实现。SAN虚拟化的目的就是让用户和应用系统把SAN作为一个单一的资源池来存取和控制。通过对目前几种SAN的存储虚拟化技术的对比,分析了存储虚拟化的技术关键,并给出了一种基于网络的SAN存储虚拟化的实现方案。
With the increasing of data in network explosively,more and more people pay attention to SAN.Currently the main storage system technology is SAN Virtualization and its implementation is in the file system layer.The target of SAN Virtualization is collecting all the portion of SAN's physical disks into a single pool which user and application can access and control.By intensive comparing the difference among several techniques of SAN Virtualization,we analyze the criteria that determine the success and viability of each technique.At last,this paper supply a networkbased solution of SAN Virtualization.
