[Abstract]:With the rapid development of information technology, the speed of information transmission is bound to be faster and stronger. With the formation of digital earth, the amount of digital information storage presents explosive development, and mass disks appear. This puts forward new requirements for the fast copy of massive hard disk data. On the basis of deep understanding of domestic and foreign rapid data replication technology, this paper makes a deep analysis of the current data rapid replication application scenarios and patterns. Aiming at the weakness of hard disk data replication system at home and abroad and the limitation of replication rate, a data replication strategy based on multi-bit and multi-interface concurrent output is proposed and studied. This paper proposes a data replication mechanism for concurrent data output based on multiple host data output interfaces, and carries out related research and implementation around this goal. The main work is as follows: (1) A fast parsing model of disk file system is built. By analyzing the physical structure characteristic, data structure characteristic, disk file system and hard disk data storage principle of hard disk, the paper puts forward the fast recognition technology of disk file system, file system driving technology, The fast parsing of disk file system is realized. (2) two kinds of data output strategies, "single mode interface data concurrent output" and "multimode interface data concurrent output", are proposed, and the whole data output architecture is completed. The strategy mode of block bit output for data output is designed. The optimal block bit partition strategy table is obtained by testing and experiment, and the multi-line data transmission is designed. The whole architecture of block bit data flow and data output. (3) the block bit partition algorithm, block bit dispatch and receiving algorithm are studied and tested to verify the feasibility and effectiveness of the strategy and algorithm. The strategy of data hash storage and recombination is put forward, and the scheme of data element hash storage is designed and implemented by analyzing the data element hash storage through the self-defined data element structure protocol. Then, according to the hash storage protocol of data element, the recombination of data element based on hash storage is studied. Two kinds of hash data recombination modes are designed and implemented. (4) the prototype system is developed on the basis of technical research, and the performance test is carried out, and the expected goal is achieved. On the basis of deep research on related technology and application strategy, according to the research goal, the paper analyzes the application requirements of the mass hard disk data fast copy system put forward by the subject. Then the hardware design and software integration of the system are realized. Finally, the function test and performance analysis of the developed prototype system are carried out. The test results show that the system is effective and achieves the expected research goal.
