Embodiment Construction

[0023] Preferred embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although preferred embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.

[0024] The quality of service mechanism in the prior art usually sets an overall bandwidth limit and an input-output operation (IOPS) limit for each user. The above limitations are usually strongly related to the physical resources (eg, device throughput) of the distributed system, and cannot cope with the different access requirements of various services.

[0025] For this reason, the present invention proposes a distributed system and its...

Abstract

The invention discloses a distributed system and a management method thereof. The distributed system comprises a plurality of service nodes, and the service nodes are used for receiving an operation request sent by a client; obtaining type information of the operation request; calling a service quality configuration strategy of the service node based on the type information, and determining the priority of the operation request; and processing the operation request according to the priority. According to the scheme, the priority strategy is formulated according to the operation type, fine-grained updating can be performed based on the actual request and the current processing capacity, and a service quality mechanism for coping with the dynamic change of cluster resources is provided.

Description

technical field [0001] The present invention relates to the field of information technology, in particular to a distributed system and its management method. Background technique [0002] A distributed system is a cluster of nodes that work together. Modern large-scale distributed systems can simultaneously satisfy multiple service requests from a large number of users under the control of a scheduling mechanism. In order to deal with the uneven occupancy of system resources caused by simultaneous access by multiple users, a distributed system usually introduces a Quality of Service (QoS) mechanism. The quality of service mechanism can assign different priorities to different users or different data streams, or ensure that the performance of data streams reaches a certain level according to the requirements of the application program. [0003] The quality of service mechanism in the prior art usually sets an overall bandwidth limit and an input / output operation (for exampl...
