Problems solved by technology

However, when the storage density of the storage medium is improved, it will also cause another problem, that is, the competition for local storage resources. For example, in a certain period of time, when multiple virtual machines perform read and write IO operations simultaneously, due to The IO data of multiple virtual machines happens to be stored on the same physical hard disk. At this time, multiple virtual machines compete for the IO performance of the same physical hard disk. If the IO performance of this hard disk becomes a bottleneck, local resources will be generated. contention problem, especially in a high-density virtualized environment, this problem is more prominent

Abstract

Embodiments of the invention disclose a reading position obtaining method and apparatus, a computer apparatus and a readable storage medium, and aims to avoid local resource competition and automatically adjust a reading position. The method comprises the steps of receiving a data reading request, wherein the request comprises related parameters of to-be-read data; according to the related parameters, obtaining load information of N first storage mediums in which N copies of the to-be-read data are located, wherein N is an integer not less than 2; and according to the load information, determining the storage medium with a smallest load as a target reading position from the N first storage mediums.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method and device for acquiring a reading position, a computer device, and a readable storage medium. Background technique [0002] With the development of virtualization technology, not only the reuse rate of server resources has been greatly improved, but also the reuse rate of storage resources has been greatly improved. [0003] In the era of physical machines, buying a storage medium is often only used by a limited number of applications, and the chimney data center structure is very popular. With the development of virtualization technology, since a storage system can store hundreds of virtual machines (VMs), the storage density of a storage medium has been greatly improved. However, when the storage density of the storage medium is improved, it will also cause another problem, that is, the competition for local storage resources. For example, in a certain...
