Virtual data center resource mapping method and equipment

Abstract

The embodiment of the invention provides virtual data center resource mapping method and equipment. By means of the method and equipment, a server management system can be made to reasonably distribute resources, and the best balance point among reliability, the resource utilization rate and the system energy consumption expense is achieved. The method includes the steps that S202, VDC resource requests are received, the VDC resource requests carry virtual machine distribution marks, and the virtual machine distribution marks are used for indicating the number K of virtual machines on which resource mapping is required to be conducted in the requests borne by a single physical server at most; S204, M virtual machines are selected from an unmapped virtual machine set Q in the VDC resource requests to form a partition P, wherein the initial value of the M is a natural number being larger than 1 and smaller than or equal to K; S206, a target physical server meeting the physical resources required by the partition P is selected, and the partition P is mapped to the target physical server; S208, M virtual machines obtained after resource mapping is conducted are subtracted from the set Q, and the S204, the S206 and the S208 are executed repeatedly till no virtual machine on which resource mapping is not conducted exists in the set Q.

Description

technical field [0001] Embodiments of the present invention relate to the field of cloud computing, and in particular, to a method and device for mapping virtual data center VDC resources. Background technique [0002] In the era of cloud computing, as society's demand for computing continues to expand, the scale of data centers is also rapidly increasing. However, behind the huge data center, the average utilization rate of its resources is relatively low, and most of the equipment is idle, which adds a huge energy consumption burden to the data center. How to reduce the energy consumption of the data center is a very serious challenge for the current data center. At present, the use of virtualization technology in the data center can effectively reduce the energy consumption of the data center and improve the resource utilization of the data center. A virtual data center is a type of elastic self-service business that provides rapid deployment, real-time response, instan...
