PI Server 2018 and PI Vision Load Balancing

I am looking for some more details on the client connection load balancing as described in the PI Server 2018 Release Announcement. The documentation states:

  • Upon initial connection, rather than all clients connecting to the primary member of a Data Archive collective client connections will now be automatically distributed to all available collective members.
    • After an HA failover, failback switches the client connection back to the original member.
    • This feature is only available for AF SDK based applications. To enable this feature on a client computer, please consult the relevant release note.

Does this apply to PI Vision connections? If so how does the load balancing happen between Vision and the PI Server. Will multiple clients accessing the Vision displays be directed to multiple PI Servers within the collective or will PI Vision only connect to  one server within the collective and all users will be "passed through" to that server?

 

What sort of parameters are used to determine which server in a collective a client will be connected to?
