Directory level service quality control method and system and access node

Abstract

The invention discloses a directory-level service quality control method and system and an access node, and the method comprises the steps: receiving a service quality configuration notice which is sent by a metadata service node and aims at a target directory; according to the service quality configuration notification, constructing a service quality data structure of the target directory, and associating the service quality data structure with directory metadata of the target directory, wherein the service quality data structure comprises a strategy for performing flow control on the target directory. According to the technical scheme provided by the invention, the directory storage structure of the distributed storage cluster can be flexibly adapted on the basis of giving full play to the data storage performance of the distributed cluster, so the deployment process of the directory-level service quality function is flexibly provided.

Description

technical field [0001] The invention relates to the technical field of the Internet, in particular to a directory-level service quality control method, system and access node. Background technique [0002] In the current cloud storage scenario, a distributed file system can be used to provide users with a directory-level file storage method. Existing distributed file systems, in order to avoid excessive use of system resources by individual users, usually provide QoS (Quality of Service, quality of service) function. IO number) to limit. [0003] The current distributed file system can establish a corresponding relationship between the user's directory space and the logical unit number (Logical Unit Number, LUN), and implement the control of bandwidth and IOPS by deploying the QoS function on the LUN. [0004] Specifically, see figure 1 After receiving the user's resource access request, the application server of the distributed file system may distribute the resource acc...

AI Technical Summary

Problems solved by technology

[0006] 1. The user's directory space must establish a corresponding relationship with the LUN, which greatly limits the underlying storage type and data distribution method

[0007] 2. When configuring the QoS function, it is necessary to clarify the corresponding relationship between the directory space and the underlying LUN, which not only puts forward higher requirements for the configuration personnel, but also reduces the deployment flexibility of the QoS function
