Have you selected a vendor yet? There is a good chance you could have a rep come out and give you some advice on your situation. One of my former students is now in charge of a large network, and he is going through the process right now of moving into a new building with a new data center. During the design phase there were decisions made for him that he didn't agree with. He had a lunch meeting with the contractors, his boss, and vendor rep. (I tagged along to offer moral support) He voiced his concerns, I backed him up, and the Panduit rep. offered some alternative solutions. In the end we had a solution that everyone was happy with. The powers-that-be wouldn't listen to him and his concerns, but a vendor rep with full glossy pictures of data center products...that did the trick. Just make sure you meet with the rep ahead of time and you agree with their suggestions before you have the meeting.
