Abstract

The invention discloses a data consistency storage method and system for an object storage device, and the system comprises a plurality of distributed servers, i.e., an OSD which is used for storing the data part of a file, optimizing the data distribution, supporting the prefetching of data, and managing the metadata of each object; and a plurality of metadata servers, namely MDSs, which are usedfor storing the attributes of the objects and providing metadata services, namely storing the information of the data of the objects stored in the distributed servers. By implementing the method andthe system, data inconsistency among a plurality of servers is eliminated; the read-write speed is high, sharing is facilitated, large-scale, high-reliability, high-performance and super-fusion storage application can be achieved, and the method is suitable for application scenarios where the requirements for expandability and storage performance are continuously improved.

Description

technical field

[0001] The invention belongs to the field of data technology, and relates to a data consistent storage method and system of an object storage device. Background technique

[0002] With the increasing development of the network, data storage methods are becoming more and more diverse, and distributed storage is also growing. The current mainstream of distributed storage is DAS storage, SAN storage and file storage NAS.

[0003] DAS is a storage method that is directly connected to the host server. Each host server has an independent storage device. The storage devices of each host server cannot communicate with each other. When accessing data across hosts, it must go through relatively complicated settings. If the host servers belong to different operating systems, it is even more complicated to access each other's data, and some systems may not even be able to access each other's data.

[0004] SAN, Storage Area Network is a storage method that uses high-spe...
