Research And Implementation Of Destribute File Storage System Based Grid

Nowadays, with hardware rapid development and a large number of popularizations of PC, and with the rapid development of the request of resource sharing, the network technology has got the development with rapid change. We want the resource of on-line PC can be used, and connection of network make this goal become possible. The computer environment develops from centralized model to distributed model, and the production of Grid is exactly on this basis. Grid make distributed calculation be systematized; and has put forward an open system structure; have offered the theoretical for sharing resources. How to leave resources unused in network, it is one of the key questions studied at present, and it is to solve the commonsense method which shares resources of the network to adopt distributed technology.In the respect of theory research: the thesis firstly introduces the characteristic of distributed technology and key technology of the distributed technology. The explained some architecture of Grid and method to put forward in solving shared resource technology, and the realization of detailed description one of the architecture of Grid (OGSA) with Globus system, and compare Grid technology, P2P technology and distributed technology. At last, the thesis introduces some algorithm of distributed technology and question needing to be paid attention to while designing the distributed system.In the respect of prototype system development: firstly, the thesis shows the principle of system design and demand for the prototype system. Secondly has introduced the soft hardware environment that the system needs. Then provide the module design drawing with system, and the realization thought of the relevant module and relevant algorithm adopted. Put forward the shorts of system and further improvement measure to the whole system finally.
