Problems solved by technology

Since different logical data have different high-availability requirements, using a single high-availability mechanism will inevitably cause system performance loss and waste of storage space
Although some high-availability systems can dynamically configure high-availability mechanisms according to needs, they cannot dynamically determine which high-availability mechanism should be used according to the needs of logical data.

Embodiment Construction

[0032] Referring to FIG. 1 , a parallel storage system applying this architecture is composed of multiple nodes, and the nodes are interconnected through a network. Nodes can be divided into four types according to their functions: metadata nodes, data nodes, client nodes, and system management nodes. Metadata nodes store the description information of logical data and respond to access requests for this information. Logical data is divided into data blocks and stored on multiple data nodes. Client nodes are consumers of logical data. The management node provides system configuration and management functions for system administrators.

[0033] Referring to FIG. 2 , the file access process of the parallel storage system when there is no fault is: firstly, the metadata service module is accessed through the function in the client framework to obtain the metadata information of the logical data. The client framework calls the function corresponding to the high-availability mec...

Abstract

This invention discloses a coexistence structure of a multi-use unit of a parallel storage system including a state test and control frame, a data service frame, a metadata service frame, a data synchronous frame, a customer end frame, a system management frame and a high usability module supporting load and unload of on-line modules, in which, the high usability module realizes that all frames call necessary interface functions in the mode of plug-in components and the frames call corresponding interfaces realized in the usable module based on the high usability kind used by logic data to finish specific function, and users can select the most suitable unit in the high usability unit to secure reliability and usability of logic data.

Description

technical field [0001] The invention relates to the technical field of computer applications, and relates to a multi-availability mechanism coexistence framework of a parallel storage system, in particular to a multi-availability mechanism coexistence framework of a distributed storage system based on a parallel file system and a distributed file system. Background technique [0002] A highly available system means that when a software or hardware failure occurs in the system, it will not cause the system to stop service, but allows the system to run with failures. In the parallel storage system, most of the existing technologies are implemented through data redundancy. If some data is not available, its backup data can provide services instead. A high-availability system usually consists of two or more nodes, which are connected to clients through the Internet, and each node has its own local storage space. [0003] Most of the existing high-availability systems only prov...
