Problems solved by technology

Using this type of technology can reduce the pressure on metadata services to a certain extent, but systems using this type of technology generally need to use multi-way mirroring to store data in order to cope with changes in calculation results when cluster members change, which will inevitably make the entire system High cost and low storage utilization

Abstract

The invention relates to a file system, an interface service device and a data storage service provision method. The file system is characterized by comprising a basic metadata service module, an extended metadata service module, a data service module and an interface service module, wherein the basic metadata service module is used for providing access to basic metadata for the file system; the extended metadata service module is used for providing access to extended metadata for the file system, and the visitor volume or the modification frequency of the basic metadata is lower than that of the extended metadata; the data service module is used for providing access to data for the file system; and the interface service module is used for providing an interface for access to the file system for external equipment, and can directly access the basic metadata service module, the extended metadata service module and the data service module.

Description

technical field [0001] The present invention relates to data storage technology. Background technique [0002] With the rapid development of computer technology and network technology, the built-in memory of the computer is gradually difficult to meet many requirements such as fast access speed, large storage capacity and low cost, so a relatively independent storage system has been developed. The storage system is usually composed of storage devices such as storage servers, which have their own interfaces and protocols, and are connected to the host computer through coaxial cables, network cables, and optical fibers. As a data storage center, the storage system provides storage services for computer hosts. [0003] One type of storage system is to establish a cluster file system on multiple physical nodes, which can directly provide data access in the form of directory / file organization. With the rapid increase of unstructured data, there are more and more applications of...
