Yes - Power Optimization
(No major change in WS2019)Another new feature in VMM 2012 - Power Optimization. Power Optimization is an (optional) sub-feature of Dynamic Optimization (only available when a host group is configured for Dynamic Optimization). Through Power Optimization, VMM helps to save energy by turning off hosts that are not needed to meet resource requirements within a host cluster and turns the hosts back on when they are needed again. Please note: Power Optimization ensures that the cluster maintains a quorum if an active node fails and therefore requires a certain numbers of hosts to remain running in a cluster. See details here:
