People often forget that the rack space, the actual physical space, is very costly. Depending on the datacenter, the power might run you just as much too. Last company I worked at was essentially forced out for using too much power per U.

To give people an idea; our main datacenter gives us 2kW per rack, and we pay extra for 4kW. A rack full of these ~700W storage pods would need about double that again, and isn't going to leave you much wiggle room.

yeah, cooling systems are designed to handle a certain amount of heat per square foot. Most of the he.net locations around here can only handle 1 15a 120v circut per rack. That's 5 low-power dual-socket servers for a full-sized rack. When I'm buying data center space I look at cost per watt and ignore the space requirements. I've not yet hit a place that was willing to sell me more power than I could use in a rack. If the space is low/medium density, I fill it with 2 or 3u chassis (I'm currently using http://supermicro.com/products/chassis/3U/833/SC833S2-550.cfm http://supermicro.com/products/chassis/3U/833/SC833S2-550.cf... because I got a good deal on a lot of them.) If it looks like they will sell me more power than I can eat with those, I pop in a few of the supermicro 2 in 1u boxes: http://www.supermicro.com/Aplus/system/1U/1021/AS-1021TM-T+.cfm http://www.supermicro.com/Aplus/system/1U/1021/AS-1021TM-T+.... This is part of why you see so many people leaving airspace between 1u servers. (me, I use the 3u servers for 'air gaps' as they run really cool.)

Would you really buy a hackish low-spec solution like this and then place it in a premium rack? Given the idea, buy 10 and place them at geographically diverse points, you may as well put them in the back room at branch offices or something. Who cares if one goes offline for a while. Hell, put them in countries with good consumer internet connectivity (japan, korea, sweden etc) and just use that. If you're going ghetto, go all the way!
