Hello mark49808
Welcome to communities.
You can add all the Horizon pods and pod federations in one collection or you can create multiple collections, based on your needs. For example, you might choose to create separate collections for each pod federation or each pod for easier management and to distribute the sync load across multiple connectors. Or you may choose to include all pods and pod federations in one collection for test purposes and have another identical collection for your production environment.
If the connection severs are all interlinked then add one primary connection server, if the connection server is interlinked with 3 then configure 3 connection servers.
Sincerely,
