ArmTechCon Recap

As you may have seen here and here, miniNodes recently got invited to participate at ArmTechCon, inside Arm’s own “Innovation Pavilion” in the Expo Hall.  Because our core business of hosting tiny Arm Servers isn’t that exciting to show off, especially at the biggest Arm ecosystem event of the year, we partnered with Robert Wolff and the awesome team at 96Boards to come up with something a bit more intriguing.   🙂

After some back and forth, we landed on a solar powered, connected, mobile developer and edge computing platform. The idea was to build a self-contained and self-powered box that could be taken out and used in geographically isolated areas, that could still have connectivity back to a central cloud provider. The actual use cases could vary dramatically, but the common theme is that there is a lack of infrastructure, electricity, or wifi in the targeted region. The box would be powered by solar panels for this iteration, but could also accept other renewable sources such as wind, hydroelectric via a waterwheel or impeller, geothermal, or more.

So, as one potential use case, we envisioned using the box in remote villages or locales that don’t have the typical infrastructure needed to teach development, AI, machine learning, edge computing, remote code or container deployment, or other advanced computer science topics.

The end goal is to provide everything as open source, with a Bill of Materials and instructions for anyone to replicate the build, using readily available, off-the-shelf parts with no customization necessary. For the demo unit though, the project hasn’t made it quite that far yet.  For this prototype, the box consisted of a foldable solar panel array, that was hooked up to a charge controller, which then fed a battery pack. The battery pack was run over to an inverter, so that we could power multiple standard devices. The first device to be powered was a 96Boards Dragonboard, that had a small LCD attached for graphical output, and had a 4G LTE cellular mezzanine which provided data to the Dragonboard.  This, as long as there is cell service, the Dragonboard has connectivity to the internet!  At that point, we had effectively built a solar powered, self sustaining compute workstation that could connect to the internet nearly anywhere!

However, because we were just doing a proof of concept, we thought it would be fun to go even one step further!  Next, we setup sharing on the Dragonboard’s cellular connection, and ran an ethernet cable out from the Dragonboard over to a Raspberry Pi 3 Compute Module.  This Pi was running a service from Microsoft called Azure IoT Edge, which is a product that allows you to remotely push containers and code to an IoT device, or receive data and telemetry back from a device out in the wild.  Thus, as long as there is adequate sunlight (or another renewable source of power) and cell coverage, the box can be remotely monitored and even updated from anywhere.  Or, thanks to its LCD and USB keyboard, it can be used as a workstation in places where infrastructure is lacking.

Another potential use case for the platform could be as an environmental monitoring solution. When equipped with a gyroscope, the box could detect movements from events such as a rock slide, avalanche, mud slide, volcanic activity, etc. Any anomoly can be reported back to the central servers immediately for analysis.

When equipped with a camera, the box could also visually monitor the environment, and detect changes in imagery such as a smoke plume for early forest fire detection, wildlife movement, vehicles approaching locations where there should not be any, or more.

Finally, because of the device’s Raspberry Pi Compute Module carrier board, the box has the ability to run targeted workloads of its own, for extreme edge computing. The workloads can be updated, changed, and monitored remotely, again due to the Dragonboard’s cellular connectivity to the Microsoft Azure IoT Edge platform.

ArmTechCon was a big success, and it’s incredible what can be built using Arm technology.  Be sure to check back for status updates as the solar compute box undergoes future development and iterations!

ARM Server Update, Summer 2018

Continuing our quarterly ARM Server update series, it is now Summer 2018 so it is time to review the ARM Server news and ecosystem updates from the past few months!  This blog series only covers the ARM Server highlights, but for more in-depth ARM Server news be sure to check out the Works on Arm Newsletter, delivered every Friday by Ed Vielmetti!

Looking at our recent blog posts, the most important headline seems to be the rumored exit from the business by Qualcomm.  Although, at the moment, this has not been confirmed, if true it would be a major setback for ARM Servers in the datacenter.  The Qualcomm Centriq had been shown to be very effective by CloudFlare for their distributed caching workload, and had been shown by Microsoft to be running a portion of the Azure workload as well.

However, just as Qualcomm is rumored to be exiting, Cavium has released the new ThunderX2 to general availability, and several new designs have now been shown and are listed for sale.  The ThunderX2 processor is a 32-core design that can directly compete with Xeons, and provides all of the platform features that a hyperscaler would expect.

Finally, in software news, Ubuntu has released it’s latest 18.04 Bionic Beaver release, which is an LTS version, thus offering 5 years of support.  As in the past, there is an ARM64 version of Ubuntu, which should technically work on any UEFI standard ARM Server.  Examples include Ampere X-Gene servers, Cavium ThunderX servers, Qualcomm, Huawei, HP Moonshot, and AMD Seattle servers.

As always, make sure to check back for more ARM Server and Datacenter industry news, or follow us on Twitter for daily updates on all things ARM, IoT, single board computers, edge computing, and more!

Prototype Raspberry Pi Cluster Board

The first samples of the miniNodes Raspberry Pi Cluster Board have arrived, and testing can now begin!

Thanks to the very gracious Arm Innovator Program, miniNodes was able to design and build this board with the help of Gumstix!  The design includes 5 Raspberry Pi Compute Module slots, an integrated Ethernet Switch, and power delivered to each node via the PCB.  All that is required are the Raspberry Pi CoM’s, and a single power supply to run the whole cluster.

We are in the process of validating the hardware, and ensuring proper functionality, but hope to launch the board soon!

miniNodes ARM Innovators Program Interview

The full Arm Innovators Program interview is now posted, and we are proud to be highlighted by Arm for our innovations in the Arm Server ecosystem!

As you can see, we are currently prototyping a Raspberry Pi Cluster PCB that will hold 5 Raspberry Pi Computer on Module (CoM) boards, with a power input and ethernet switch built in.

This Raspberry Pi Cluster Board will allow the Docker, Kubernetes, OpenFasS, Minio, and other cluster projects to easily develop, test, and build their software in a cheap and convenient way, with no cabling mess.  Home automation, IoT, and hardware hacking are other potential uses for the board.

We’re still a few weeks away from launching, but keep watching this space as we will be sure to make an announcement as soon as it is ready!

Fedora IoT Edition Approved

The Fedora Council has authorized a new Fedora Edition (as opposed to a Spin), dedicated to IoT devices and functionality!  Fedora ARM developer Peter Robinson is heading up the effort, congratulations to him!  He has information available on his blog located here:  https://nullr0ute.com/2018/03/fedora-iot-edition-is-go/, and there is also an official Ticket capturing the Approval located here:  https://pagure.io/Fedora-Council/tickets/issue/193

The Wiki is just getting built out now, so there is not a whole of information on it quite yet, but keep checking back as it takes shape:  https://fedoraproject.org/wiki/Objectives/Fedora_IoT
