Method and apparatus for power-efficiency management in a virtualized cluster system

摘要

A method and apparatus for power-efficiency management in a virtualized cluster system. The virtualized cluster system includes a front-end physical host and at least one back-end physical host, and each of the at least one back-end physical host comprises at least one virtual machine and a virtual machine manager. Flow characteristics of the virtualized cluster system are detected at a regular time cycle, a power-efficiency management policy is generated for each of at least one back-end physical host based on the detected flow characteristics, and the power-efficiency management policies are performed. The method can detect the real-time flow characteristics of the virtualized cluster system and make the power-efficiency management policies thereupon to control the power consumption of the system and perform admission control on the whole flow, thereby realizing optimal power saving while meeting the quality of service requirements, so that a virtualized cluster system with high power-efficiency is provided.

1. A method for power-efficiency management in a virtualized cluster system, wherein the virtualized cluster system comprises a front-end physical host and at least one back-end physical host, and each of said at least one back-end physical host comprises at least one virtual machine and a virtual machine manager for managing said at least one virtual machine, the method comprising:
detecting flow characteristics of said virtualized cluster system at a regular time cycle, the flow characteristics including characteristic data of sub-flows entering the virtual machine, resource consumption data and quality of service data on each of said at least one virtual machine; generating a power-efficiency management policy, utilizing a processor within a back-end physical host, for each of said at least one back-end physical host based on the detected flow characteristics; and performing said power-efficiency management policies.
