Companies like IBM, HP and Sun (now Oracle) have been promoting data center containers — modular and quickly-deployable server, storage and networking infrastructure in shipping containers — as companies rush to build up their IT arsenals to conquer the cloud. Now, it looks like some startups are getting into the game.

A company called Silver Linings (clever) is touting its “rafts” which consolidate server racks, power distribution and cooling equipment, and as luck would have it, makes them perfectly suitable for data center container duty. According to the company, each raft can accommodate up to 250U. Energy efficiency features include variable speed fans and a proprietary heat exchanger called an “Augmented Convective Cooling” that helped the company achieve a PUE rating of 1.4 in tests.
