Hello, I don't know the answer for your first question, but a domain is like a logical connection of multiple server, cluster and other instances of them. So you only must manage the domain not every part of it. Imagine you have one server in Russia and one in Germany and not the possibility to create a virtual LAN but you can connect them to one domain and you must not care about the connection between them (SCA cares about) . Hope this helps a bit. Johannes Stoye
