The invention designs an energy efficiency qualitative evaluation technology for multi-index fusion of a cloud data center. In the field of cloud data centers, in order to better and effectively improve the data center, a perfect index system is required to be proposed, and a multi-index fusion energy efficiency qualitative evaluation technology is designed. The indexes are associated with each other, a principal component analysis method is applied, original multiple data center energy efficiency indexes are converted into a few of unrelated comprehensive indexes, most of information of a data center energy efficiency index system can be reflected, a to-be-evaluated index set can be reduced, and the calculation complexity of subsequent steps can be reduced. Besides, an evaluation method based on a radial basis function neural network is introduced, knowledge and experience of experts are obtained by learning existing samples, multiple energy efficiency indexes are taken as consideration for evaluating the energy efficiency factors of the data center, and only one comprehensive evaluation value is output.
Description
technical field [0001] The invention relates to the technical field of energy efficiency evaluation of cloud computing data centers, in particular to an energy efficiency qualitative evaluation method for multi-indicator fusion of cloud data centers with different architectures. Background technique [0002] With the development of the Internet, the total amount of global data continues to grow, and the load on cloud data centers is also increasing. Due to the limitations of material conditions, the energy consumption of cloud data centers is also becoming more and more worrying. In the context of global advocacy of sustainable development, it is necessary to evaluate the energy efficiency of cloud data centers in order to better improve cloud data centers. While providing people with better green services, it can also achieve sustainable development. In terms of current data center energy efficiency evaluation, there are quite a few energy efficiency evaluation indicators....
