Problems solved by technology

[0003] Object storage is a new network storage architecture that combines the advantages of file storage and block storage. The QoS (Quality of Service) solution for conventional storage uses token buckets, priority Level queues and other methods control the request dequeuing process. For example, in block storage, I / O requests are finally unified to the volume for execution, so I / O control can be performed on the volume, but in object storage, there is no volume control. Concept, unable to process I / O request priority

Abstract

This application discloses a method for processing I / O requests, which is applied to object storage gateways to obtain the QoS templates of each abstract client for processing I / O requests; obtain the pending I / O request set transmitted by the network front end; For each pending I / O request in the / O request set, the QoS value of the pending I / O request is determined based on the abstract client corresponding to the pending I / O request; based on the QoS value, the pending I / O request set is determined to be The order in which I / O requests are processed. In an I / O request processing method, system, device, and computer-readable storage medium provided by the present application, the object storage gateway determines the QoS value of each pending I / O request based on the QoS template of the abstract client, and based on the QoS value The processing sequence of each pending I / O request is determined, thereby realizing priority processing of the I / O request in the object storage system.

Description

technical field [0001] The present application relates to the field of storage technology, and more specifically, to an I / O request processing method, system, device and computer storage medium. Background technique [0002] In the storage field, I / O (Input / Output, input / output) resources involve reading and writing of the system, which will affect the performance of the system. How to allocate I / O resources is a matter worth considering. [0003] Object storage is a new network storage architecture that combines the advantages of file storage and block storage. The QoS (Quality of Service) solution for conventional storage uses token buckets, priority Level queues and other methods control the request dequeuing process. For example, in block storage, I / O requests are finally unified to the volume for execution, so I / O control can be performed on the volume, but in object storage, there is no volume control. Concept, unable to process I / O request priority. [0004] To sum ...
