分析目前各种海量存储系统的体系结构研究重点,提出一种海量存储系统的5层体系结构,分别是存储物理层、存储连接层、存储网络层、存储表示层和存储应用层.通过各个层次之间相互提供/调用服务的方式,使用多种存储技术构建海量存储系统.在此基础上,设计并实现了一种基于智能网络磁盘及其文件系统的层次化海量存储系统,通过实验验证了层次化体系结构的海量存储系统的可行性和正确性.
Based on the research results of mass storage system,a hierarchical structure with 5 levels has been proposed.It consists of storage physical level,storage link level,storage network level,storage expression level and storage application level.Different storage technologies can be implemented into different level.These 5 levels work together by services supplying and functions invoking.A practical system based on this structure has been developed.The experimental results proved the feasibility and correctness of this structure.
