unless your redundant controller is in another building up to
30-50Kilometers away in another city along with an entirely redundant
cluster.. So in essence, you have 4 controllers (2 controller pairs).
The question is really "how much $$$ is your data worth?".

EVA's have the ability to replicate itself to an entirely different
controller over a Wide-area SAN using dark-fibre.
