Expandable storage system and control method based on objects

Abstract

Combining file with block mode, the invention puts forward a brand new object interface in order to overcome disadvantages of system structure and mode of user service in current mass storage system. The system includes I pieces of metadata server, N pieces of object storage node, and M pieces of client end connected to each other. Three parties among client ends, object storage node and severs are realized. The system provides high expandability, and synchronous growth of memory capacity and collective bandwidth of data transmission. Changing traditional data management and control mode, object storage node OSN executes fussy functions for managing data at bottom layer of file system, and MS implements management of metadata. Based on object storage, the system realizes adaptive management function.

Description

technical field

[0001] The invention belongs to the technical field of computer information storage, and in particular relates to an expandable object-based storage system and a control method thereof. Background technique

[0002] An ideal storage system should have the following five characteristics: security, cross-platform data sharing, high performance, scalability, and intelligence. The three structures of Direct Access Storage (DAS), Network Attached Storage (NAS) and Storage Area Network (SAN) that are widely used today have different degrees of defects, and it is difficult to have the above five characteristics at the same time; the essence of these systems has never changed , that is, the basic transmission unit is block (Block) or file (File), and it lacks the intelligence and other characteristics of the storage system with object (Object) as the interface. As storage requirements increase and storage applications become increasingly complex, block or file-based...
