Affinity Rule

 An Affinity Rule is a rule affecting placement of virtual machines on a host. You can implement affinity rules in Turbonomic via placement policies. Also, Turbonomic discovers vSphere Host DRS (Distributed Resource Scheduler) rules when DRS is enabled, and implements them as placement policies. Imported rules are enabled by default, but you can disable specific rules as necessary.

Turbonomic supports Place, Don’t Place, Merge, and License policies. The Place and Don’t Place policies implement Affinity and Anti-affinity rules, respectively. Affinity rules place groups of workloads together on specific hosts so you can easily audit the usage of those workloads. Anti-affinity rules keep specific workloads from running together on the same host to support HA and prevent a single point of failure at that host.
