Dynamic power management system and dynamic power management method

Abstract

The invention discloses a dynamic power management system which comprises a resource pool utilization factor monitoring module, a resource pool utilization factor maintaining module, a host component state monitoring module, a power management strategy generating module and a power management strategy executing module. The resource pool utilization factor monitoring module is used for acquiring resource pool utilization factor data of virtual machines; the resource pool utilization factor maintaining module is used for maintaining the resource pool utilization factor data; the host component state monitoring module is used for acquiring running state data of components in physical hosts; the power management strategy generating module is used for generating corresponding power management strategies according to the resource pool utilization factor data and the running state data; the power management strategy executing module is used for adjusting running states of the physical hosts and power of the components in the physical hosts according to the power management strategies. The invention further discloses a dynamic power management method. The dynamic power management system and the dynamic power management method have the technical advantages that the shortcoming that only existing physical hosts are shut down in the traditional power management schemes can be overcome, fine-grained dynamic power management can be implemented, and the response speeds of resources can be obviously increased.

Description

technical field [0001] The invention relates to the technical field of power dynamic management, in particular to a dynamic power management system and method. Background technique [0002] With the development of science and technology and the improvement of people's awareness of environmental protection, low-carbon life has become a life attitude of people. Similarly, many companies' electronic products also reflect the pursuit of low-carbon environmental protection. For example, smart devices with automatic screens, Both low power standby and dynamic power management are aimed at reducing power consumption for greener products. [0003] Currently, some server virtualization products on the market provide dynamic power management functions, and most of the products that provide this function migrate the virtual machines running on hosts with relatively low After a few physical hosts are installed, shut down the physical hosts directly. After the utilization rate of the v...

Problems solved by technology

[0004] Simply by turning on and off the physical host, in some computing situations where the amount of calculation changes greatly, it will cause the physical host to switch between the startup and shutdown states continuously, which will not effectively reduce power consumption, but will cause the corresponding response time of the system to be longer. In addition, , in some abnormal situations, such as the situation that the physical host cannot be shut down normally during the shutdown process, the dynamic power management strategy cannot be successfully executed at this time, which will cause the host to exist as a zombie host

If the number of application accesses in the virtual machine suddenly increases, the current resources cannot meet the requirements, and additional resources are needed in a short period of time, at this time, if the idle physical host is turned on through dynamic power management, there will be some time lag
