We have 10 4400-100 controllers located at a central location, which manage approximately 750 APs across 20 remote locations. Is there a best practice concerning the distribution of those APs across the controllers. We currently distribute the APs from a single remote site across 2 or more controllers for the purposes of fault tolerance. My concern is channel/power selection when APs are located on different controllers. Is there a downside to distributing the APs across the controllers?
