Just add my $.02 here... When you become dependent on cooling - make sure you also have some sort of generator capable of running the A/C.
We tried running some of our LAN on a generator, but since the AC wasn't on generator power the tiny (8x16) room that I have went from 64 F to 80 F in 20 mins. Not good.

My server room is about 12x12 and I have a 3 ton [1] air cooled unit a 1 ton water cooled unit as a backup (normally off) and the buildings AC. James. [1] Yes I know that 3 ton is too big for such a small area so I have some of its cool air venting into a hallway also, so the compressor doesn't die. Servers make for some heat and based on the heat generation I needed a 3 ton.

If you *need* 15 tons, I would consider TWO 8 ton units. With a single unit it's all or nothing, and the nothing part will suck if it happens to you.

Currently, I have two HVAC bids regarding the expansion of our server room. (It will seem strange to have that room below 80 degrees, and I am not kidding with that number!). We have two proposals and with two different units, both 15 tons. One is by Stulz, and one is by Liebert. Anyone care to offer their opinions/experiences/etc on the advantages one has over the other?
