Embodiment 1

[0033] The invention proposes an improved virtual machine disk scheduling method. The basic idea of ​​this method is to dynamically divide the disk array into a work area and a ready area, distribute resources with the work area as the main user, and use the virtual disk connected to the virtual machine as a unit to dynamically optimize the virtual disk layout according to the real-time load situation. . In this way, the virtual disk layout can achieve a higher level of load balancing. The specific method includes four parts: preprocessing, resource selection, postprocessing and interaction.

[0034] S1, the preprocessing process, this stage means to improve the traditional virtual disk, realize the execution point of the virtual disk from centralized to distributed, the distributed virtual disk architecture is as attached figure 1 As shown, at the same time, change the passive sleep mode of the disk based on the idle threshold to active. This will help alleviate the perfor...

Abstract

The invention discloses a virtual disk scheduling method based on openstack, and relates to the field of virtual disk scheduling in a cloud environment. The method specifically comprises the steps that a disk array is dynamically divided into a working area and a ready area, resources are distributed to the working area which is taken as a main user, dynamical optimization is conducted on a virtual disk layout by taking a virtual disk of a bit-connected virtual machine as a unit according to real-time load conditions, and therefore the virtual disk layout reaches a higher load balancing level.

Description

technical field [0001] The invention relates to the field of virtual disk scheduling in a cloud environment, in particular to an OPENSTACK-based virtual disk scheduling method. Background technique [0002] Cloud computing is a new type of computing in the Internet age, and has gradually become an important development strategy in many countries. The openstack cloud computing project originated in the United States. Its openness lies in the fact that it has created a framework standard and API, which users can use as Foundation for building cloud computing solutions. Since openstack supports mainstream image formats such as KVM, xen, and vmdk, customers can more easily put virtual machines running in the cloud in the internal IT environment of the enterprise without worrying about being locked in by cloud system technology. [0003] Disk virtualization technology has a long history, common standards include: RAID, JBOD, SAN, etc. At present, by abstracting multiple physica...
