Embodiment Construction

[0052] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0053] The process of writing to the object storage method is as follows: figure 1 shown.

[0054] In step S110, the metadata is stored in the MDS, and the primary and backup copies of the file data are stored in the OSD.

[0055] Step S120, when the client performs a write operation, it reads the replica location information of the object file corresponding to the write operation from the MDS, and sends a write request to the OSD where the master replica of the object file is located according to the replica location information.

[0056] The client reads a replica location information of the object file corresponding to the write operation from the MDS, and the replica location information includes service replica set information of the object file accessed by the write operation request. After the client parses the information, it sends a write request t...

Abstract

The invention relates to a method and a system for storing an object. Metadata are stored in a metadata server, and a duplicate of file data is stored in an object storing server. In the method, when carrying out writing operation, a client terminal reads the duplicate position information of an object file of the writing operation from the metadata server and transmits a writing request to the object storing server in which a main duplicate is located according to the duplicate position information; the object storing server in which the main duplicate is located receives the writing request, updates the local main duplicate and forwards the writing request to an object storing server in which a backup duplicate is located; after receiving the writing request, the object storing server in which the backup duplicate is located updates the local backup duplicate and transmits a response to the object storing server in which the main duplicate is located; and the object storing server in which the main duplicate is located receives the response and transmits a writing operation success response to the client terminal after receiving the response of the object storing server of part of backup duplicates. The invention can improve the writing performance in a storing system.

Description

technical field [0001] The invention relates to the field of computer storage, in particular to an object storage method and system thereof. Background technique [0002] The OSD (object storage) structure of the cluster file system using object storage combines the advantages of NAS (Network-attached storage, network attached storage) and SAN (Storage area network, storage area network), in terms of performance, data sharing and scalability Compared with the first two storage structures, it shows a good structural advantage. [0003] The concept of OSD was first proposed in NASD (Network Attach Secure Disks), which advocates changing the traditional block-based storage interface to an object-based storage interface. The object-based interface includes both file and block information, providing a structural basis for intelligent storage. By adopting object storage, the file system can realize the shared data mode. Files are in the system in the form of self-describing obj...
