Abstract:
A method of reducing power consumption of a server cluster of host systems with virtual machines executing on the host systems is provided. The method includes recommending host system power-on when there is a host system whose utilization is above a target utilization, and recommending host system power-off when there is a host system whose utilization is below the target utilization. Recommending host system power-on includes calculating impact of powering on a standby host system with respect to reducing the number of highly-utilized host systems in the server cluster. Recommending host system power-off includes calculating impact of powering off a host system with respect to decreasing the number of less-utilized host systems in the server cluster.
Abstract:
Methods and systems for cluster resource management in virtualized computing environments are described. VM spares are used to reserve (or help discover or otherwise obtain) a set of computing resources for a VM. While VM spares may be used for a variety of scenarios, particular uses of VM spares include using spares to ensure resource availability for requests to power on VMs as well as for discovering, obtaining, and defragmenting the resources and VMs on a cluster, e.g., in response to requests to reserve resources for a VM or to respond to a notification of a failure for a given VM.
