The invention relates to a distributed hard disk system. The distributed hard disk system comprises a mobile hard disk array and a hard disk array master controller system. The mobile hard disk array comprises a plurality of hard disks and parallel data interface connecting lines of the hard disks and is used for storing copy data. The hard disks are provided with interface data controllers used for being connected to an external I / O interface of a server and recording the names, the sizes, the number and the logical relationship of copy files and catalogues. The hard disk array master controller system is used for controlling the interface data controllers, uploading data files in a synchronous parallel mode, and downloading and recording the names, the sizes, the sum number and the logical relationship of the copy files and the catalogues of the hard disks. According to the distributed hard disk system and the data migration method thereof, the transmission rate of the data files and the catalogues can be effectively increased, and the use efficiency of the data files and the catalogues can be improved.
Description
【Technical field】 [0001] The invention relates to the field of big data storage, in particular to an end-to-end distributed hard disk system and a data migration method therein. 【Background technique】 [0002] In supercomputing services, data transmission efficiency is a universal bottleneck factor. Big data transmission in the current distributed system, whether uploading or downloading, is generally carried out through single-point replication. That is, first, through a certain server, the relevant data distributed on the hard disks or hard disk arrays of the original business system are transferred to the storage medium in the form of global copying, while on the supercomputing side, another data copy is required. The server completes the reading, uploading and distribution of big data to the supercomputing designated area. This many-to-one, one-to-many large-scale data aggregation, processing and replication process completely depends on the computing performance and I...
