Manager count HP P4000
Looking for the best practice regarding the amount of managers that should be running in a Single Site config. I saw that this was not that easy to find (as HP is aiming on Multi-Site Clusters).
For a single site next does count.
2 Nodes, 1 FOM, 3 managers
3 Nodes, 0 FOM, 3 managers
4 Nodes, 1 FOM, 3 or 5 managers (5 preferred)
Just make sure you have an odd manager count, so 1 node can fail ad you still will have 2 managers running.
This could mean that you could run without a FOM in a 4 Node SS Cluster. (3 managers running on 3 Nodes, but nothing may go wrong when 1 node already has failed.)
