在本文中，我们提出了两个能源模型的基础上的统计分析服务器的操作行为，以尽量减少能源消耗在云计算提供商的数据中心。基于这些模型，云提供商中的节能引擎（ESE）决定从轻负载服务器迁移虚拟机（VM），然后将其关闭或将其置于睡眠模式，或者保持当前服务器运行并准备好接收任何新的负载请求。这两种模式之间的主要区别是将服务器从睡眠模式或关闭状态置于操作模式所需的能量和时间。因此，该决策是根据客户端和云提供商之间的SLA在节能和所需性能之间进行权衡。我们显示的结果基于在服务器的AC输入端进行的实际功率测量，以确定在空闲状态、睡眠状态、关闭状态以及在这些状态中的任意两个之间切换的情况下消耗的能量。此外，我们还测量了VM迁移过程中源服务器和目标服务器的功耗。
In this paper, we propose two energy models based on a statistical analysis of a server's operational behavior in order to minimize the energy consumption in data centers at cloud computing providers. Based on these models, the Energy Savings Engine (ESE) in the cloud provider decides either to migrate the virtual machines (VMs) from a lightly-loaded server and then turn it off or put it in a sleep mode, or to keep the current server running and ready to receive any new load requests. The main difference between the two models is the energy and time required to put the server in operational mode from a sleep mode or from an off state. Therefore, the decision is a tradeoff between the energy savings and the required performance according to the SLA between the client and the cloud provider. We show results based on actual power measurements taken at the server's AC input, to determine the energy consumed in the idle state, the sleep state, the off state and in the case of switching between any two of these states. In addition, we measured the power consumed by the source and the destination servers during the migration of a VM.
