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

The invention discloses an I / O (Input / Output) request processing method, which is applied to an object storage gateway. The I / O request processing method includes the steps: acquiring QoS (Quality ofService) templates of abstract clients for processing I / O requests; obtaining a to-be-processed I / O request set transmitted by a network front end; for each to-be-processed I / O request in the to-be-processed I / O request set, determining a QoS value of the to-be-processed I / O request based on an abstract client corresponding to the to-be-processed I / O request; and determining a processing sequenceof the to-be-processed I / O requests in the to-be-processed I / O request set based on the QoS value. In the I / O request processing method, system and device and the computer readable storage medium, theobject storage gateway determines the QoS value of each to-be-processed I / O request based on the QoS template of the abstract client, and determines the processing sequence of each to-be-processed I / O request based on the QoS value, thereby realizing priority processing of the I / O requests 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 ...
