...i think who debian is the best on stability for domain0.

If i readed the article well i must place a load balancer(with it's backup with failover)to balance the request over the two servers.
index.php?t=getfile&id=436&private=0

It can be a simple way to do it but i must buy another 2 machines and the packet should pass first on the load balancer and then they can be elaborated in one of the two clusters.
index.php?t=getfile&id=434&private=0

I think it's a good way if i use central storage but i want use drdb because if i use a central storage i must use failover on that and it's too expansive and i can loose on performance.

The second option is to develop a paravirtualized machine with 3 indipendent virtual machine.
The configuration is very clear and simple but i must divide the process on the 3 servers so when i request a php page with mysql from server0,server0 ask server 1 for the datas and elaborate it so i should create 3 line:
eth0 - connect the server to the switch(and internet)
eht1 - used for heartbeat and drbd
eth2 - used for the connections between server0 and server1
index.php?t=getfile&id=435&private=0

what do you think?
what is the best solution for security,performance and easy installation?

Thanks and i'm sorry if i think too much that necessary! Very Happy
