Configuring Dynamic Optimization and Power Optimization


Dynamic Optimization (DO) is a new VMM feature that initiates the live migration of VMs that are on a cluster to improve load balancing among cluster nodes and correct any placement constraint violations.

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.

Dynamic Optimization 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 Dynamic Optimization.

Note

By default, a host group inherits DO settings from its parent host group.

Power Optimization, an optional feature of Dynamic Optimization, is enabled only if a host group is...
