Study Of Data Access And Storage Interface In The Cloud Storage System

The cloud storage technology emerged under the circumstances that network congestion occurred with the proliferation of information, it can integrate large numbers of different types of storage devices in the Internet and provide a uniform, standard of storage access services compared with traditional network storage.This paper introduced the design and implementation of a cloud storage system which supports the dynamic expansion of storage equipment, and provides three kinds of standard interfaces including CIFS protocol, NFS protocol and Restful for the guests. On this basis, this paper conducts research on the synchronous management mechanism of the application interface layer, integrated security verification mechanism and the system reliability. It also proposes solutions for this problem.Firstly, this paper conducted research on the industry standard architecture of cloud storage system and put forward the cloud storage system structure including the storage management, application interface layer and access layer. Further, this paper discussed the technical requirements, design and implementation of cloud storage system in detail, then studied and implemented the key technologies of the application interface layer including the synchronous management mechanism based on the script and remote commands, security verification integration mechanism based on NIS service, load balance of interface node and Failover mechanism based on CTDB public IP pool technology and DNS service. At last, this paper completed the comprehensive functional verification and testing on cloud storage system in practice. Its result satisfied the requirements of design.In summary, this paper designed and implemented cloud storage system for enterprise applications, the users can access to mass data through the standard agreement interfaces. It can solve the problems of synchronized management, user authentication and other ones in the cloud storage system and provide users with stable and convenient services. To a certain extent, it can solve the problem of mass data applications of any enterprise.
