Can someone describe a case in which is needed to configure a serverfarm with more than one probe associate to it?
Moreover is not clear for me what can happen in case of fails of a single probe. Will it be that all serverfarm will be out fo service in this case? Or all probes associated to the serverfarm have to be failed in order to have the server farm in a out of service state?
I know that in case of more than one probe associated to a real server the ACE is doing a logic AND between them ( fail-on-all command to modify this behavoiur) but not sure if this is still valid for a serverfarm.
i have mentioned a scenario where in we use multiple probes in single serverfarm (the shopping website e.g).
lets have this config:
serverfarm host SHOPPING
So ACE will send both TCP-80 and TCP-443 for both servers (A & B).
So if you see show probe detail you wil get two real server bind with each probe. And when you run show rserver you will see status based on probe result and serverfarm confiugration probe logic (AND or OR).
Now if let say TCP-80 probe fails for server A only (taking your q?) then with default mode of AND server-A will be declare dead and rmove from load balancing decision. Same probe is working well for B (along with TCP-443) so that will remian inservice.
Now it will be great if you share your doubt base on above configuration.
