I have recently purchased 3 x HP proliant dl360 G3 servers and need some advice.
I want to use 2 servers for the website and 1 server will be a backup.

I need to know a few basic questions.
Do both servers need to be exactly the same spec for load balancing?
Will the data be identical on both of the servers hard drives or would i have to use a storage array to connect both servers to it.

thank you in advance
