Thinking about Aruba, now we're told 'no' to controllers.
My company needs a wireless overhaul. We've been doing our research for a while and we are leaning heavily to Aruba. A couple months ago my coworker that was taking the reins on this project left and now me and my boss are trying to get a grasp on everything. Plus, the local Aruba sales rep and network engineer quit recently and Aruba is scrambling to get someone to take over. Now my boss had a conference call with Gartner and they are telling us to not go with controllers. That controllers are a thing of the past and that we can manage up to 8000 AP's with Aruba's Instant AP. Gartner was very rude on the conference call too. So rude that my boss is annoyed (and my boss is very difficult to annoy).
We have 25 branch locations and managing all the branch sites with one Instant swarm sounds a little fishy.
My boss is going back to Aruba with this, but I wanted to ask the hive mind if they have any experience with it. 25 branch offices with one Instant AP swarm (~150 APs total)? What does a controller get us specifically over Instant AP. Isn't it the controller that gives us the nice login page with self registration? (We really like that.)
I'm just trying to get ideas and second opinions.
