WLAN 4400 Controller - Distributing AP's across controllers

Unanswered Question

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?

The best way to handle this is to put all the AP's for a site onto the same controller.  This would reduce the number of mobility handoffs when a client roams between controllers.  When mobility events have to occur for roaming it just adds a little latency.

As far as the RRM concerns, just make sure you have all the controllers in the same mobility and RF groups.  The controllers will communicate between eachother and sub-RF groups will be created for the controllers that have AP's that can hear eachother.
