Data center energy saving method and device

Abstract

The invention discloses an energy-saving method of a data center. The energy-saving method is a method for optimizing the server end and the network end of the data center and specifically includes the steps of collecting load information of the network end and the server end; formulating a corresponding scheme of displacing virtual machines on a server for an application task newly submitted by a user according to the current load condition of the server end; selecting appropriate paths for data transmission among the virtual machines according to the current load condition of the network end. Meanwhile, the invention further provides an energy-saving device of the data center. The energy-saving device comprises a data collecting module, a server allocating module and a network path allocating module, wherein the data collecting module is used for collecting the load information of the network end and the server end, the server allocating module is used for formulating the corresponding scheme of displacing the virtual machines on the server for the application task newly submitted by the user according to the current load condition of the server end, and the network path allocating module is used for selecting the appropriate paths for data transmission among the virtual machines according to the current load condition of the network end.

Description

technical field [0001] The invention relates to the field of industrial informatization energy saving, in particular to a data center energy saving method and device. Background technique [0002] In the data center, whether it is online applications, such as web search, or background tasks, such as distributed file storage systems represented by scalable distributed file systems and distributed computing represented by MapReduce, all run on large scale distributed computing platform. At the same time, with the continuous expansion of data center scale and the application of network topology fat tree, the energy consumption cost of operators increases year by year. Statistics show that globally, the total energy consumption of data centers accounts for about 8% of the total global power consumption; according to Gartner's report, the energy consumption of data centers accounts for about 25% of the total operating costs. [0003] Existing solutions can be divided into two c...

Problems solved by technology

[0006] The purpose of the present invention is to solve the problem that there is currently no joint optimization scheme for the server and the network, that is, there is currently no scheme for optimizing network and server-side task allocation at the same time, resulting in the existing data center energy consumption optimization scheme not being able to meet the target data center performance. The ideal requirement for consumption optimization
