Hello, I'm hoping to just gain clarification on the optimal design in Aruba OS 8 in this non "best practices" physical architecture. There are three separate university campuses, each with a single hardware 7xxx controller. There is also a virtual mobility master.
Is there an advantage here to cluster these physically separate controllers, or should we simply rely on LMS/backup-LMS config in the AP Groups? The controllers are not layer 2 adjacent, and we definitely want the APs to terminate on the local controller unless there is a failure.
So I believe creating three separate AP groups for the three sites and specifying the LMS/backup LMS is sufficient for this requirement.
The main point I'm asking is: would creating a layer 3 cluster significantly reduce failover time, or provide another benefit I'm not understanding? I don't want a clustering mechanism to kick in that would have APs terminating on the wrong controller, and so the AP Group basic LMS/backup LMS keeps things more static and controlled, from my understanding.This my first ArubaOS8 deployment, so just trying to confirm that I'm not missing anything, thanks!
