HP got the industry buzzing this week when it announced plans to build server hardware based on low-power ARM processors. And while it will be a while before Project Moonshot’s tech hits data centers, that’s not stopping folks from dreaming up some big data implications.

Better yet, some enterprising souls are already demonstrating what its ‘cloudy’ future could look like.

Over at CNXSoft,  Noritsuna Imamur of the Open Embedded Software Foundation, shows off Google App Engine running on a Pandaboard cloud cluster.

Norisuna had a comparison table that showed the Pandaboard cloud (OMAP4 @ 1GHz – 12 Cores) uses 4x times [less] space and 5x less power (50W vs. 257 W) than a Xeon 1.8GHz Quad Core server with about the same amount of processing power and memory (6GB vs. 8GB).

Neat!
