Understanding HA and Additional polling Concept.

We have a main poller server and 4 additional poller server for polling and we want to implement HA for same.

How many server is needed in HA?

One extra server for each system you want to protect with HA, so 5 new standby servers for everything you just described.

    No, the active/standby relationship requires a 1 to 1 pair
