Abstract

The embodiment of the invention discloses a bandwidth traffic control method, device, equipment and computer readable storage medium of a distributed block storage system. The method comprises the following steps: performing slicing processing on a to-be-written/read data block of a user according to a preset slicing capacity, if the current token number in a bandwidth token bucket is not less than the required token number of the target data slice, and issuing the IO operation of the target data slice; if the current token number is less than the token number required by the target data slice, blocking the IO operation of the data target slice, and then executing the IO operation until the current token number in the bandwidth token bucket is not less than the token number required by thetarget data slice; determining a token generation rate by the bandwidth token bucket according to the bandwidth quota, wherein the token number required by the target data slice is decided by the slice capacity value and the capacity corresponding to each token. Through the method disclosed by the embodiment of the invention, the bandwidth upper limit control of the distributed block storage system is realized, the real-time performance jittering is small on the basis of external providing the bandwidth traffic limiting, and the stability of the distributed block storage system is improved.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of distributed storage, and in particular, relate to a bandwidth flow control method, device, device, and computer-readable storage medium of a distributed block storage system. Background technique [0002] Block storage generally refers to a redundant array of independent disks composed of a controller and a group of disk drives, and provides fixed-size RAID (Redundant Array of Independent Disks, disk storage array) blocks as LUN (logical unit number, logical unit number) ) volume. The distributed block storage system combines multiple hard disks through certain rules to form a large-capacity logical disk. The logical disk can be further divided into a set of data volumes customized by users and provide external services. Distributed block storage systems should consider advanced features such as data redundancy, fault recovery, and volume data clone snapshots. [0003] For the stor...
