Load Balance Approach To Save Power On Cloud Datacenter

In the field of scientific research, Increasing importance has been attached to power management of modern data centers. It has been a hotspot in computer science field. With the rapid develop of virtualization technology, modern data centers widely apply virualization technology to enhance themselves. The datacenters which use virualization technology can be managed easly. To some extent. The virualization technology improves datacenter ease of management and reduces the expense to purchase hardware. The virtualizied hardware is flexible. The virutalized system can deployed effectively. But the virtualied datacenter can't simply apply the traditional power management solution. Existing solutions are excessive reliance on workload consonlidation achieved by virual machine live migration. This solutions aren't applicable in high workload and normal workload. Hence, the study of datacenter with high workload and normal workload is important.DVFS technology is commonly used in modern processor. The dynamic power consumption of processor have square relation with the fequency. It means that the processor should work in the suitable fequency to reduce processor's power not the maximum fequency. According to this feature of modern processor, this paper proposes a scheduling method for purpose of saving power through balance the workload of all the processors and a load balance framework to save power on cloud datacenter. The creative feature of the paper can be summaried as follows: Firstly, it can be applied to the virtualized datacenter, and raised a novel save power method. Secondly, this paper proposes a creative load balance framework to save power on cloud datacenter, a virtualized machine migration strategy and uses this strategy in the framework. Finally, we simulated this strategy and the framework using Cloudsim simulation tools.
