Scientific American has a interesting article on a Data Center in a box. Basically it is a standard shipping container full of Sun Servers. I am our our IT manager would like one! it should fit on any house’s driveway, a stylish addition to any home.
It is an interesting spin on the old IBM data recovery model where they turned up with a duplicate of your system in a truck in event of a major failure. The key change is it is being sold as a greatly cheaper option than a traditional data center. All it needs is power, a water supply (cooling) and I suppose given our current weather, a location not prone to flooding.
