VMware ESXi Custom Power Management Settings improve efficiency

Custom Power Management Settings for Power Savings in vSphere 5.5

posted

VMware vSphere serves as a common virtualization platform for a diverse ecosystem of applications. Every application has different performance demands which must be met, but the power and cooling costs of running these applications are also a concern. vSphere’s default power management policy, “Balanced”, meets both of these goals by effectively preserving system performance while Read more...

Power Management and Performance in VMware vSphere 5.1 and 5.5

posted

Power consumption is an important part of the datacenter cost strategy. Physical servers frequently offer a power management scheme that puts processors into low power states when not fully utilized, and VMware vSphere also offers power management techniques. A recent technical white paper describes the testing and results of two performance studies: The first shows Read more...

Power Management and Performance in ESXi 5.1
