Jon with Basic Network - it implies you have all in one network for everything.
If you have a storage network that is L3 routable and you don’t want to use guest network - then when you create a zone - use storage label and define what bridge will be used to get there. If it’s not guest bridge you wan to use - then use the management Bridge.
