2 Server Cluster !?

[Vladimir Bobic]

Ahoy everyone,

I'm interested to know if there is anyway to run 2 servers cluster in which:
- if 1 server fails other one continues to serve clients.
- when failed server is back, force elections to favored server
I'm aware that there is possibility for both servers to work 
independently not knowing for each other,
difference that could immerge is not issue.
Regards,
Vladimir
