I am getting ready to purchase a large number of controllers for sites around the world. Because of geographic/bandwidth reasons, it is not practical to do N+1 redundancy worldwide. I need to do N+1 (most sites will be 2 5508 controllers) redundancy in each major site. With that being said, I am going to be purchasing twice the number of AP licenses as I need solely for the purpose of HA...
Does anyone know of any plans to run a "floating" license model where we could pool worldiwde licenses (think ISE endpoint licensing), OR a plan for an "HA/Secondary" controller. This would be a controller that serves no purpose but to backup another controller.
Because of the # of APs that can be hosted on the 5508s I can not justify purchasing numerous controllers, just for additional HW redundancy.
Any info would help, thanks!!
