As the ARM server market began to emerge in press and powerpoint, it was not hard to separate the hype from reality: it was a lot of hype. Spread by well-meaning advocates trying to change the world and give Intel a run for their money, these myths created unrealistic expectations on whether ARM chips are worthy of server applications, when they will ship, and how hard they will be to use. I applaud the early leaders including APM and AMD for their early efforts on 64-bit products. While they have tried to balance their excitement and the uncertainty of semiconductor development schedules, there are nonetheless a few myths that need clearing up. Here are six common ones: [Read more...]
Calxeda has announced its second generation SoC, the ARM® Cortex™ A15 based EnergyCore™ ECX-2000. This is the industry’s first ARM-based SoC enabled for full OpenStack clouds, Xen and KVM virtualization, and delivers twice the performance of the first generation ARM-based server SoCs. Calxeda will demonstrate the new platform running Ceph object storage and OpenStack at this week’s ARM TechCon conference in Santa Clara, October 29-31. Notably, HP has selected the ECX-2000 for an upcoming Moonshot server in early 2014. Calxeda also added a second 64-bit SoC to its roadmap that is pin-compatible with the ECX-2000, accelerating the availability of production 64-bit Calxeda-based systems in 2014 and protecting customers investments.
While this is big news, there is a far more important story to be told. The new ECX-2000 is just the next step on the journey to a far more efficient datacenter. This journey will fundamentally reshape the datacenter infrastructure into a fleet of compute, storage, networking, and memory resources; the so-called Software-defined Data Center.

Advances in multi-core computing have allowed far greater compute densities such that nearly all datacenter racks run out of available power far sooner than physical space. Traditional High Performance Computing (HPC) X86 clusters can consume upwards of 400W per rack unit (U), this means that a typical data center rack with a 5KW – 8KW circuit can be maxed out in as little as 1/4 or 1/2 of the available space. Many of today’s forward thinking IT leaders are asking “Why can’t I have both extremely dense computing and better power efficiency?”
IEEE held their annual fest for uber-techies at SuperComputing ’12 this week in Salt Lake City. With over 8000 attendees flocking to the snowy site in spite of the economy and impending fiscal cliff, this event has become a mecca for anyone seeking the next great technology in computing hardware for serious work. In the old days, it was all about (Tera)Flops and Fortran. These days it is about Big Data, hardware acceleration, interconnect fabrics, storage, and green computing. Wandering around in the massive exhibit hall, one could see name badges from companies like eBay, Amazon, Peer One Hosting, and Dreamworks, right alongside the traditional attendees from leading universities, National Labs, and the Departments of Defense and Energy.
So, what’s a little core like ARM doing in a place like this? Its all about the data. “Data Intensive Computing” in HPC is pronounced “Big Data” in the enterprise. And the two communities have another thing in common: both are seeking more energy efficient solutions to large computations challenges. So naturally, they are turning to ARM with great hopes for the future.
Want to test some cloudy code on an ARM server?
Now you can! For Free!
Calxeda, OpenStack, HP, Canonical, and Core NAP hosting have now donated the hardware, software, and facilities to provide FREE access to HP’s Calxeda-based Redstone servers using the TryStack sandbox. This is so cool; you can provision a free server instance and play to your hearts content. Upload code or images. Develop and test your software. Use the OpenStack API’s on ARM and realize “Its just Linux!”. And pay nothing. For more information on how to access this, see the OpenStack Blog
Obviously, there has been a lot of interest about this new class of servers that can dramatically reduce power and space requirements for scale-out workloads. Thats why you came to this site! Some call these “micro-servers” (Intel). Some call them “Extreme Low Power Servers” (Gartner’s analysts). And yes, some have affectionately called them “Wimpy Nodes” (See Carnegie Mellon University’s “FAWN” paper.)
