ARM server running on pedal power demoed at Red Hat Summit
With x86 and a few high-powered RISC chips dominating the list of the most powerful computers on Earth, you might be wondering what's the big deal with ARM and it's push into the server space. Well, this is the big deal. The image above is of Jon Masters powering a Calxeda-server from HP with nothing more than a bicycle. OK, so there's a bit more to the setup -- including a 400 watt inverter, a 35 Ah battery, a UPS and a Pedal-a-Watt -- but the gist of it is that Masters was able keep 32 ARM cores humming along just by pedaling his road bike at the Red Hat Summit. The demo was mostly meant as a proof of concept, but we can easily imagine our future robot overlords putting us to work keeping their network of servers running. On the plus side, pedaling to power the Internet might help solve our global obesity epidemic. For a quick tour of the rig, check out the video after the break.
Calxeda benchmarks claim that its server chips are 15 times more power efficient than Intel's
Calxeda may have been given the bum's rush by HP's Project Moonshot, but the company isn't taking it lying down. It's released benchmarks for its ARM-based server technology that claims it's 15 times more power-efficient than the comparable Intel Xeon. Rigging up a 1.1GHz Energycore ECX-1000 with 4GB RAM against a 3.3GHz Xeon E3-1240, the former consumed only 5.26 W compared to the 102 W of Intel's high-spec chip. While it certainly wasn't faster, power efficiency is a key concern for data centers looking to keep costs down, and if the trend continues, Santa Clara will come to regret AMD's recently announced love-in.
HP and Calxeda's Moonshot ARM servers will bring all the boys to the yard (video)
HP and Calxeda's indiscreet partnership has been revealed to the world: Project Moonshot is a new server based around a brand new ARM-based EnergyCore system-on-chip. These new units are so efficient that a four core version, packing 4GB DRAM, consumes just five watts at full pelt -- for perspective, that's less than your average tablet. The other funky innovation is that all the server nodes now share a single power, cooling, management and storage system rather than carrying it themselves. In terms of space saving, the Redstone four unit chassis you can see in the image above can hold 288 of the little blighters. If you set your alarm clock early to learn more about efficient server architecture, head on past the break for two videos, including a tour of HP's server labs and some press release goodness.
