Wow - what a horror! I'm linking to Apple.com! This is a systems design and install we did for Molinare over the summer for the Tour De France. Rupert and Graham fettled the SAN configuration with Tony and I doing the fibres. See it all here.
However - don't believe what you read on manufacturer's websites!

“All the systems worked incredibly well. We had a few glitches to begin with but, thanks to the support of Root6, these were fixed very quickly. Reliability wasn’t an issue — we had very few issues with FCP during the three weeks and Xsan performed fantastically”.

It wasn't all that!
