Hi Simon, Your proposal is correct,I currently have the recommended setup: 2 machines with nice amount of cores and RAM, with management server and mysql installed. Usage server is not currently used, BUT we do use MySQL replication for some form of HA.
However, the drawback that I see is that the management server on the second head node must be down otherwise it causes the replication to fail pretty quickly. So in case of failure of the first head node the admin needs to login to the second head node and initiate the management server (or maybe you can script it and automate this). Last requirement needed is a script that automates MySQL backups (crontab can be used for that).
