Are you asking about the affinity rules on ESXi or exactly what do you want to know??

You answered it. How does that work?
A funny thing: I thought my vmware guy said Infinity
I found the doc with the recommendations to avoid all actives on the same server, chassis or site

Redundancy and Failover Considerations
Application-layer considerations (such as Unified CM Cluster over WAN or Unified CCE Remote Redundancy) are the same for virtualized (UC on UCS) or non-virtualized (MCS 7800) deployments.
However, since there is no longer a 1:1 relationship between hardware and application instances, "placement logic" must be taken into account to minimize the impact of hardware unavailability or unreachability:

The way this works is that you create the affinity rule to make sure the VMs are always together or you configure them in a way in which the VMs never are placed in the same HW.
You would use the alway together for example for a DB and a web server, the always on separate servers for a CUCM PUB/SUB.
You can read the VMWare explanation here:
