Problems solved by technology

As the background storage system that supports the operation of its main business, their data access response to users is similar to a "best effort" model, without distinguishing between users, and without too much QoS control on access services, it is difficult Meet the QoS requirements of different users

Embodiment Construction

[0065] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0066] like figure 1 As shown, the system is mainly composed of three functional entities: metadata server ("central node"), data storage server ("storage node") and client. The metadata server is responsible for storing and managing the metadata information (file control information) of all files in the cloud storage system; the data storage server is responsible for storing specific file data blocks, not involving file control information, and providing data read and write to the client at the same time Service; the client is the use platform and entrance of the cloud storage storage system, providing users with a storage access interface.

[0067] Its overall strategy mainly includes the following parts:

[0068] (1) Classification of service quality based on user QoS requirements

[0069] One of the goals of QoS control in cloud storage ...

Abstract

The invention discloses a QoS control method of a cloud storage system based on differentiated service. By setting the QoS control mechanisms of a metadata server terminal and a data storage server terminal, the method of the invention can guarantee the QoS demands of cloud storage system users of different levels multidimensionally and comprehensively, and realize the differentiate service.

Description

technical field [0001] The invention belongs to the field of cloud storage systems, and mainly realizes a cloud storage system quality of service (Quality of service, QoS) control method based on differentiated services. Background technique [0002] Cloud storage is a new concept extended from the concept of cloud computing, which refers to the application of cluster technology, virtualization technology, distributed file system technology, etc., to integrate a large number of heterogeneous storage devices through application software and high-speed network A technology that integrates and works together to provide large-scale data storage and access functions. Simply put, it is to store all basic service content on multiple computers, and use the limited storage space on multiple computers to form a unified massive storage space to provide external services. Among them, the cloud storage system, also known as the distributed file system in the usual sense, is the most cri...
