Title:
DATA STORAGE METHOD, DEVICE AND SYSTEM
Document Type and Number:
WIPO Patent Application WO/2017/000094
Kind Code:
A1
Abstract:
A data storage method, device and system, which are used for storing data to be stored of a source node in a distributed storage system in a distributed manner. The method comprises: determining N storage nodes from the distributed storage system (S202); acquiring bandwidth information about each storage node in the N storage nodes (S204), wherein the bandwidth information about each storage node is a transmission bandwidth of a data transmission path from each storage node to the source node; according to the data to be stored and the bandwidth information about each storage node, allocating corresponding data to be stored to each storage node (S206); and sending the data to be stored allocated to each storage node to each storage node (S208). According to the transmission bandwidth, a data block size is allocated to each storage node, and a larger data block is allocated to a storage node with a large transmission bandwidth, so as to improve the efficiency of data transmission, and shorten the access time of data, thereby achieving the rational utilization of resources.
