Realization Of A Software Based On Distributed Numerical Calculation Model

The development of information technology makes the needs to technology of storage grow exponentially, and bring huge challenge because of the development of the storage technology. It brings infinite business opportunities for storage market.The cloud storage technology can integrate large numbers of different types of storage devices in the Internet. Its irreplaceable advantage is to provide a uniform, standard of storage access services compared with traditional network storage.This thesis introduced the design and implementation of the cloud storage systems. The system supports storage equipment dynamic expansion and provides CIFS agreement, NFS agreement and Restful three standard interfaces for the visitors. On this basis, this thesis expound the application synchronous management mechanism interface layer, integrated security verification mechanism and the system reliability. It also gives the solutions and proves a success in practice.Firstly, the author studied 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. Next, the author discussed the technical requirements, design and implementation of cloud storage system in detail. These details provided the basis for the further research. On that basis, the author studied and realized several key technology of application interface layer: 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, the author completed the comprehensive functional verification and testing on cloud storage system in practice. Its result satisfied the requirements of design.In conclusion, the author designed and realized cloud storage system for enterprise applications. Visitors can meet mass data through the standard agreement interfaces. It can solve synchronized management, user authentication and other problems 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.
