Abstract:
1. A system for dynamically regulating power consumption in an information technology (IT) infrastructure having a plurality of compute nodes interconnected over a network, the system comprising: at least one virtual machine (VM) host deployed at each of the plurality of compute nodes, the at least one VM host is operable to host at least one VM guest, and the VM hosts on different ones of the plurality of compute nodes are version compatible to enable migration of the VM guests among the VM hosts; and a management module connected to the plurality of compute nodes over the network to receive a native measurement of a performance metric of a computing resource in each of the plurality of compute nodes, the management module is operable to dynamically regulate power consumption of the plurality of compute nodes by migrating the VM guests among the VM hosts based at least on the received performance metrics of the plurality of compute nodes, wherein the management module is operable to determine whether there is sufficient capacity at another compute node of the plurality of compute nodes to accommodate the at least one VM guest from the one compute node and upon the determining that there is sufficient capacity at the another compute node, migrating the at least one VM guest from the one compute node to the another compute node.
