Dynamic Optimization (DO) is a VMM feature that initiates live migration of VMs that are on a cluster, to improve load balancing among cluster nodes and to correct any placement constraint violations.
VM Load Balancer (Node Fairness), available in Windows Server 2016, will be turned off if dynamic optimization is enabled in VMM fabric.
It can be configured with a specific frequency and aggressiveness on a host group, which determines the amount of load discrepancy required to trigger a live migration through DO.
DO settings can be configured for the CPU, memory, disk I/O, and network I/O.
By default, VMs are migrated every 10 minutes with medium aggressiveness. You must take into consideration the resource cost (for example, the network) of extra migrations against the advantages of load balancing among cluster nodes, when setting the frequency and aggressiveness for DO.
By default, a host group inherits DO settings from its parent...
