To create minimal downtimes during failover, I also create an HA Group. If the master fails, you can use the licenses on the standby for 30 days. I use the master redundancy configuration to synchronize the configuration, user data and of course the licenses. The two controller run in standalone mode. The design looks like this, from a logical point of view: Master Standby – Design But you can use a variation of the fast failover feature. Only the active controller can terminate AP’s in this design. Keep this in mind during the setup of the controller. The Master Standby design requires two controllers, obviously. So this is just a plan B if you cannot use the benefits of an implementation with VMM. Just to make it clear, you get the most features, the most benefits and the most outcome from a deployment with VMM. Likely the same design as with ArubaOS 6.x. So the big question is how to build an environment with ArubaOS 8 and two controllers. Many customers deploy two controllers today. ![]() This time, I will not include the VMM in my scenario. In the last posts about ArubaOS 8, I talked a lot about Virtual Mobility Master.
