The World’s First 130 Watt Server Cluster

Boston Viridis Power Optimized Server Cluster Based on Calxeda EnergyCore

Calxeda’s approach to driving power optimization in the datacenter goes well beyond the processor.  We focus on enabling our partners to achieve rack level power efficiency based on our technology. Last week, Boston Limited announced their 2U Viridis platform with 24 Calxeda EnergyCore(TM) server nodes, 96GB of memory, and 6TB storage is measuring 130W “at the wall”. This equates to just 5.5W of power per server inclusive of memory, disk and chassis-level overhead.  At a fraction of the power of a traditional x86 server node, the Viridis server cluster based on Calxeda EnergyCore will allow datacenter operators to experience an order of magnitude improvement in efficiency.

Dell & Apache: More than just a donation

Today’s Dell announcement of their donation to the Apache Software Foundation is a huge milestone not only for Calxeda but the entire ARM server ecosystem. Supporting and engaging the open-source community has always been a high priority for the Round Rock based company, evidenced by their contributions and leadership in multiple open-source projects like OpenStack and other Apache projects. But this particular announcement is more than just a generous donation to a non-profit foundation.

Calxeda EnergyCore-Based Servers Now Available

We spent a lot of time at various tradeshows around the world in June and the #1 question we were asked was “when can I get my hands on a Calxeda-based server?” I am happy to tell you the wait is over.

We have been working with Boston Limited in the UK, a highly respected  solution provider, for about a year to bring an excellent Proof of Concept (POC) platform to market called “Viridis”.  Boston currently has about 20 customers lined up for beta testing and a pipeline of hundreds of others interested in evaluating the platform.  Boston is taking orders now from users in Europe, Asia and the US with shipments beginning later this month.

The Register published a great article today highlighting the features of the Boston Viridis platform:

Boston Viridis is a perfect option for those users who want to port their code, run benchmarks, and optimize their workloads for ARM.  This highly configurable solution allows users to create their ideal initial testing environments with options ranging from 4 to 48 Calxeda EnergyCore server nodes in a 2U form factor.

We look forward to working with Boston and other systems providers to enable the market with Calxeda-based POCs.  Stay tuned as we learn about success stories users experience with Calxeda EnergyCore-based solutions over the coming months.

Calxeda CEO to speak at GigaOM Structure

Barry Evans, Calxeda CEO and co-founder, has been invited to speak at the upcoming Cloud Fab, GigaOM Structure, in San Francisco on June 20. If you have never been to Structure, it is the industry’s premier event for advancements in Cloud Computing hardware and software innovations, with a list of speakers from some of the industry’s movers, shakers, and entrepreneurs.  Barry will be on a panel with AMD’s Andrew Feldman (formerly CEO of SeaMicro) and Guido Appenzeller, CEO of BigSwitch Networks. Their panel is titled “Inside the data center: it’s all about the fabrics”. This is a hot area.  AMD’s acquisition of SeaMicro, and Intel’s acquisition of fabric assets from Cray, have recently piqued interest from around the industry. As we move from the age of the “Clock Wars” to the age of the “Core Wars”, and now to the age of the “Efficiency Wars”, the cluster and datacenter interconnect fabric and software-defined networking are emerging as the source of the next series of breakthroughs.

Calxeda will also have live hardware running in our booth at the show. Come by to for a demo of OpenStack and other Cloud infrastructure running on Calxeda-based hardware from the industry’s leading system vendors.

If you would like a discounted ticket to attend Structure, Calxeda can help you out. Go to our website, where you will find a link to obtain a discount code for 25% as a friend of Calxeda!

Hope to see you in San Francisco!

Dell Enters the ARM Race for Servers

Dell announced today that they are working with TACC (Texas Advanced Computing Center) to provide access to ARM-based servers for developers and researchers. Here’s one of many articles: . This is an important announcement, since Dell is a big player in the markets best suited for ARM such as Internet web properties, Big Data, Cloud Service Providers, and HPC outfits. As such, this further validates the market demand for ARM-based servers, and helps accelerate the growth of the required ecosystem.

The observant reader will notice that Dell is using the Marvell Armada XP SOC, because, as Dell pointed out, “the Marvell parts are already available in sufficient quantities”. But Dell positioned themselves as “agnostic”, and confirmed in interviews that they are also working with Calxeda.

As the ARM server market continues to take shape, the one constant you can expect is choice. Thats the beauty of the ARM business model! Congratulations Dell! Welcome to the party!

Calxeda demonstrates Ubuntu 12.04 LTS on EnergyCore SoC

This week, Calxeda is showing a live Calxeda cluster running Ubuntu 12.04 LTS on real EnergyCore hardware at the Ubuntu Developer and Cloud Summit events in Oakland, CA. This is not an FPGA demo. This is the real deal on real silicon; quad-core, w/ 4MB cache, secure management engine, and Calxeda’s fabric, all up and running.

On stage at UDS

Calxeda’s “Greenbox” (get it?) prototype supports up to 48 quad core SOCs in a 2U package

Ubuntu 12.04, with support from Canonical, is the 1st Linux distribution with full support for ARM as a 1st tier server architecture. Incorporating OpenStack’s cloud management infrastructure, Ubuntu 12.04 is designed to support the world’s largest cloud environments, where Ubuntu enjoys commanding market share today.

After months of discussion, debate, claims, and counterclaims, the industry can now begin a fact-based dialog about Calxeda-based servers. What applications are appropriate? Are they fast enough? How much can they really save large internet and IT shops? Do they really consume only 5 watts each? In other words, this new category of technology is moving beyond Powerpoints and on to proof-points. Ok, we will still pepper the market with pretty presentations, but at least they will contain real benchmarks and measurements made on real systems. We will begin communicating benchmark results on soon.

So, back to Oakland…Running Ubuntu 12.04, we are demonstrating a standard LAMP stack (running Calxeda’s website) along with other popular web frameworks such as node.js and Ruby on Rails, provisioning of OpenStack Nova compute instances, and even Canonical’s Metal-as-a-Service bare-metal provisioning. The cluster we are running is a Calxeda EnergyCard prototype in a 2U chassis that supports up to 48 quad-core nodes at under 300 watts, with up to 24 SATA drives. For more information about UDS, please see Remote Participation for UDS is available at

While exciting to see, this demo really shows just how easy it is to move modern software over to Calxeda and Ubuntu. Literally, it all just worked. The code came up without any modifications. Just load and go.

The Linux community will see immediate benefits from such a server for building Linux kernels and distributions. A complete build of the Ubuntu 12.04 kernel took less than an hour to compile on a single node, 1/4 the time of current ARM build platforms. With a larger Calxeda cluster, a full build of the entire distro will take hours, instead of weeks.

Now that Calxeda EnergyCore has been seen in the wild, you can expect more sightings at a variety of industry events, and end-users shipments will begin over the next 4-8 weeks. Volume shipments are expected to begin early this Fall from HP and other system vendors. Be sure to check our website frequently to get updates.

Who said that hardware is boring? Let the fun, and games, begin!
