I do not understand the difference between configuring controller clustering in "Managed Network -> Services -> Clusters" or in "Managed Network -> Redundancy -> High Availability". Both possibilities are described in the manual but I cannot figure out the detailed differences. Is "High Availability" an "old" type and "Cluster" a new one?
Is there someone who can explain it to me :-)?
High Availability is the 'old' way of doing redundancy when you do NOT have a cluster.
When you have a cluster you do NOT configure HA, as the cluster handles load-balancing etc.
The reason both are still explained in the manual is that you are not forced to build a cluster and without it HA comes back in to play.
Please do understand that a cluster is the way to go in ArubaOS8.
