Data Grid is one of the important research fields for Grid Computing. To improve the system efficiency, this paper puts forward the strategies of ring replication and thread replication. Compared with many other replication strategies and considered in different grid infrastructure, the strategies of ring replication and thread replication can boost the efficiency of Data Grid. Having studied how to improve the efficiency of replication at the degree of node, we will study at the degree below node, at which we use the viewpoint of the file-parted replication to divide the data Grid files into several blocks that are replicated parallel between the data Grid sever points then. Finally, based on the experiment, we prove that the file-parted replication can boost the efficiency of Data Grid rapidly.
