Abstract

The present invention provides a method and device for implementing QoS in a distributed storage system. After receiving a read-write operation instruction, it applies for tokens from the read-write operation token bucket and the bandwidth token bucket respectively. The total number of stored tokens is related to the quality of service that the user actually needs to purchase. Only when there are tokens in the token bucket, can the token be applied for from the token bucket, and only from the read and write operation tokens and bandwidth commands. Only after the token is applied for in the bucket, the operation corresponding to the read and write operation instructions can be performed. The number of tokens in the read-write operation token bucket is used to limit the number of read and write operations per second (IOPS), and the number of tokens in the bandwidth token bucket is used to limit the bandwidth of read-write operations. It achieves both IOPS and bandwidth requirements.

Description

technical field [0001] The invention belongs to the technical field of distributed storage, and in particular relates to a method and device for realizing Qos in a distributed storage system. Background technique [0002] With the rise of cloud computing, distributed storage has entered the era of cloud storage. Cloud storage provides users with customizable and pay-as-you-go services, and users can purchase storage services corresponding to the quality of service (QoS) according to their actual needs. [0003] QoS guarantee is very important for distributed storage scenarios with limited resources, especially for streaming multimedia application scenarios, which have high requirements for the number of read and write (I / O) operations per second (IOPS) and bandwidth. Require. [0004] The implementation method of Qos in the distributed storage system in the prior art cannot meet the high requirements of IOPS and bandwidth at the same time. [0005] Therefore, it is an urg...
