Abstract

The invention is suitable for the technical field of computers and provides a dynamic placement optimization method and system of a virtual machine on a server cluster. The method comprises the steps of respectively establishing a server status energy consumption model, a virtual machine migration energy consumption model and a server status switch energy consumption model and establishing a server cluster energy consumption model according to the server status energy consumption model, the virtual machine migration energy consumption model and the server status switch energy consumption model; calculating out average waiting time of user requests according to probability that servers are in each state, amount of current user request servers and amount of the servers in each state; using the minimum value of server cluster energy consumption as an optimization target according to the server cluster energy consumption model under a preset condition to obtain a dynamic placement optimization scheme of the virtual machine. The dynamic placement optimization method disclosed by the invention can model a dynamic change process of a load and a status of the server cluster and utilizes the minimum value of the server cluster energy consumption as the optimization target to obtain the dynamic placement optimization scheme of the virtual machine.

Description

technical field [0001] The invention belongs to the technical field of computers, and in particular relates to a virtual machine dynamic placement optimization method and system on a server cluster. Background technique [0002] At present, the problem of energy consumption in cloud service centers and data centers based on large server clusters is becoming more and more prominent. Virtual machine technology is an effective way to improve data center resource utilization and achieve energy saving and emission reduction. The most effective way to achieve energy saving is through management of virtual machine technology. It is to formulate a reasonable virtual machine placement strategy. [0003] Due to dynamic changes in server resources, virtual machine requirements, and user requests, being able to automatically adjust the dynamic placement of virtual machines with relevant changes is an important means of rationally placing virtual machines. Dynamic placement of virtual m...
