Jul 08, Facebook released Cassandra to open source under the Apache license. Facebook uses Cassandra as email search system where, as of last summer, they had 25TB and over 100m mailboxes. This video gets into more detail on the architecture and design: http://www.new.facebook.com/video/video.php?v=540974400803#/video/video.php?v=540974400803. My notes are below...

We look at the construction and design of both types and present results demonstrating that high-density DCs are a better choice for reducing the owners cost. These results apply to new construction and mostly-unconstrained retrofits. Densities of 1000 watts per square foot of work cell are being achieved with good efficiencies. Modern designs of 200 to 400 watts per square foot of work cell are much more common, but cost more. Costs of the architectural space, power systems and cooling systems are reviewed as are the operational costs for these systems. High-density DCs do cost less. The challenges for the high-density DC are also called out and suggestions for successful operation are made.
