This TechNet Wiki come from Microsoft Partner Kristian Nese, who talks about Dynamic Optimization and Power Optimization in SCVMM 2012:
"In VMM2012, Dynamic Optimization replaces the host load balancing that is performed for Performance and Resource Optimization (PRO) by the PRO CPU utilization and PRO Memory Utilization monitors in System Center Virtual Machine Manager (VMM) 2008 R2."
VMM brought us a lot of new stuff. We'll take a closer look at the optimization options this time. We've "Dynamic Optimization" and "Power Optimization".
To support dynamic optimization, you must have a well configured cluster that also supports live migration. For power optimization, the computers must have a baseboard management controller (BMC) that enables out-of-band management. (Power optimization is an optional feature of dynamic optimization). So what`s the benefits here, and why should you care?
The answer is short: Server utilization.
