Ask HN: Apple North Carolina Data Center

My 12 year old son lives, breathes, eats, sleeps Apple. His iPad is his prize possession. He has been asking me about Apple building a data center in North Carolina. He is pretty technical in his questions. If anyone has any input, I would really appreciate it so I can better help him understand what he wants to know. 1. What hardware will they use? XServe's? Mac Pro's? * I actually would not even have a clue here as to what they are doing. He assumes that since it is Apple they will be using Apple hardware? 2. Operating systems: OS X Server? Linux? * again, he assumes OS X Server. 3. How much storage, disk space will they have and how will it be setup? * I tried explaining that perhaps they will have 42U racks filled with NAS devices, maybe each holding 24 drives (which takes up 5U of Space) so approximately 5-6 of these per rack (allowing for air flow, power, wiring, etc) and several racks of these. Also, that maybe one "server" would control several racks of these drive setups. Does anyone have any thoughts on the architecture/setup of the facility?
