Embodiment Construction
[0042] The basic idea of the present invention is as follows: the file is divided into a plurality of fixed-length data blocks, which are stored in single or multiple storage node servers according to the distributed file system strategy, and all data blocks have parameter marks to be accessed within a unit period Number of times, data block parameters are stored in the main server, and hot files will be sorted according to the number of times they are accessed to confirm the range of hot files. When a new client starts, it will obtain some data blocks of the hotspot files provided by the main server, and the positions of other hot data blocks in other clients. In a distributed file system with multiple clients, the hotspot file data blocks and their location information will be allocated to each client according to the policy. When the client's application program requests to read hotspot file data, the client will initiate access to other clients according to the location ...
