%X In order to enhance the efficiency of data access and resolve the problems of existing quorum systems, such as no differerce between the nodes, great latency in data access and low storage utilization, this paper presented a new quorum system based on privileges classification of all nodes. The system adjusted each quorum dynamically by means of the usage of proxy. Besides, divided the nodes of the system into different grades according to data storage time, and designed the corresponding data read and write protocols. As a conclusion of the system performance analysis, it shows that the scheme has the advantages of high data access efficiency, storage reliability, flex to be extended and so on.
