World’s First Bicycle Powered ARM Server
By Jon Masters, Red Hat
At this year’s Red Hat Summit, I gave a talk entitled “Hyperscale Cloud Computing with ARM processors” (video coming soon). In the talk, I introduced and gave a live demo of the world’s first bicycle powered ARM server (HP Redstone server powered by Calxeda EnergyCore quad-core ARM processors). I wanted to make a point that the (hyperscale) future will be all about energy efficient technology. The quad-core Calxeda EnergyCore ARM-based chips used in my demo (powering the HP Redstone server system) use only 5W of power at full load, including the RAM, fabric interconnect, and management controller. The (pre-production) test system had 8 of these installed, for a total of 32 ARM cores. At 5W per quad-core, that’s still only 40W to run all of the compute within the server system.
