Hierarchical Structure of Mass Storage System
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.
