When I have to server, each running multiple VM's what would be the correct number of ES nodes ?
The goal is to still have a functoning ES cluster even when 1 server completely dies due to a hardware failure.
Currently I have the following setup but something tells me ES would not survive a sudden los of one of the hosts:
Server A: ES01 , ES02
Server B: ES03, ES04
ES01,2,3,4 form a ES cluster where most settings are default.
Should I configure settings for number of replicas so that there's always a complete replica of the data on both of the hosts ?
Or is the best option to add another server and have 1 ES node per server ?
