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.
Can It be possible if we used one server as Standby server for all servers and if one of the server goes down it will get connect to standby server.
Can this be possible if we have only one server is standby (in HA)and if any of the polling engines goes down then it will get connected to standby server in HA
No, the active/standby relationship requires a 1 to 1 pair
