OpenFabrics Alliance (OFA) Completes Interoperability Debug Test Event at the University of New Hampshire-InterOperability Laboratory (UNH-IOL)

The OpenFabrics Alliance (OFA) recently held an interoperability debug test event, October 22-26 at UNH-IOL in Durham, New Hampshire. The debug test event is the first of two test events required for OFA members to become part of the OFA’s Interoperability Logo Program (OFILP) and to obtain the coveted OFA logo for products tested by the UNH-IOL. The next test event, Interop GA, will take place in late November 2012. The OFA plans to announce the next logo list in early 2013.

Eleven vendors participated in the recent event including: Canonical, CentOS, Chelsio, DataDirect Networks, Emulex, Intel, NetApp, Mellanox, Red Hat, Scientific Linux, and SUSE. Products tested included:

  • Linux operating systems from Canonical-Ubuntu, CentOS, Red Hat, Scientific Linux, and SUSE
  • Storage targets from DataDirect Networks and NetApp
  • InfiniBand host channel adapters and switches from Intel and Mellanox
  • iWARP adapters from Chelsio and Intel
  • RDMA over Converged Ethernet (RoCE) adapters from Emulex

The debug test event, designed to build cooperation with the InfiniBand®, iWARP and RoCE Ethernet communities, focused on industry-wide interoperability using the OFA software–a standards-based high bandwidth, low-latency networking stack for Remote Direct Memory Access (RDMA).

The OFA Interoperability Working Group (OFA IWG) recently enhanced its interoperability test plan to include RoCE products in the logo program. Additionally, the OFA has a new process for distributing OpenFabrics Software (OFS) by confirming that all new software and updates are pushed upstream into the kernel. The OFA and all distributors pull from the same kernel source when creating software packages, ensuring that OFED and are in sync before the software is released. This most recent Interop Debug test event was the first time that the new OFS build (OFED 3.5) was tested.

“We are pleased to complete yet another test event for OFA members as it delivers significant benefits to both end-users and vendors that bring those interoperable products to market,” said Jim Ryan, chairman, OFA. “Our logo program not only allows end-users to have the choice to deploy multi-vendor products, but also offers seamless interoperability which facilitates easier adoption of RDMA and low-latency I/O technologies by IT managers.”

About the OFILP

Launched in 2007, the OFA’s Interoperability Working Group (IWG) created the OFILP and the Interop Test Plan and works in collaboration with UNH-IOL to execute the tests. The OFA IWG grants an “OFA Interoperability” logo to products which have participated in and passed two required test events - Interop Debug Event and Interop GA Event.

The OFA Cluster at UNH-IOL is available to all OFLIG members. Access to the cluster can be scheduled for one week at a time either in person or remotely through VPN. The cluster includes one of the largest and most diversified collections of RDMA products including: Chelsio and Intel iWARP RNICs, Emulex RoCE adapters, Intel DDR and QDR InfiniBand HCAs and switches, Mellanox DDR, QDR and FDR InfiniBand HCAs and switches, DataDirect Networks DDR, QDR and FDR InfiniBand Storage Targets and NetApp DDR and QDR InfiniBand storage targets. The cluster uses a head node which stores all of the latest Linux and Windows operating systems along with all of the OFED binaries so that all servers can be reconfigured within 30 minutes with the OS and OFED version that vendors choose to test. The OFA IWG test plan includes specific tests which target InfiniBand, iWARP and RoCE, and it also includes transport independent tests which work on all devices regardless of the transport.

The test plan and the logo list can be accessed at the following sites:

We are rapidly moving to a brave new world of interconnected smart homes, cars, offices and factories known as the Internet of Things (IoT). Sensors and monitoring devices will touch every part of our lives. Let's take a closer look at the Internet of Things. The Internet of Things is a worldwide network of objects and devices connected to the Internet. They are electronics, sensors, software and more. These objects connect to the Internet and can be controlled remotely via apps and programs. Because they can be accessed via the Internet, these devices create a tremendous opportunity to inte...

We all know that data growth is exploding and storage budgets are shrinking. Instead of showing you charts on about how much data there is, in his General Session at 17th Cloud Expo, Scott Cleland, Senior Director of Product Marketing at HGST, showed how to capture all of your data in one place. After you have your data under control, you can then analyze it in one place, saving time and resources.
The Internet of Things (IoT) is growing rapidly by extending current technologies, products and networks. By 2020, Cisco estimates there will be 50 billion connected devices. Gartner has forecast revenues of over $300 billion, just to IoT suppliers. Now is the time to figure out how you’ll make money – not just create innovative products. With hundreds of new products and companies jumping into the IoT fray every month, there’s no shortage of innovation. Despite this, McKinsey/VisionMobile data shows "less than 10 percent of IoT developers are making enough to support a reasonably sized team....
Just over a week ago I received a long and loud sustained applause for a presentation I delivered at this year’s Cloud Expo in Santa Clara. I was extremely pleased with the turnout and had some very good conversations with many of the attendees. Over the next few days I had many more meaningful conversations and was not only happy with the results but also learned a few new things. Here is everything I learned in those three days distilled into three short points.
DevOps is about increasing efficiency, but nothing is more inefficient than building the same application twice. However, this is a routine occurrence with enterprise applications that need both a rich desktop web interface and strong mobile support. With recent technological advances from Isomorphic Software and others, rich desktop and tuned mobile experiences can now be created with a single codebase – without compromising functionality, performance or usability. In his session at DevOps Summit, Charles Kendrick, CTO and Chief Architect at Isomorphic Software, demonstrated examples of com...
As organizations realize the scope of the Internet of Things, gaining key insights from Big Data, through the use of advanced analytics, becomes crucial. However, IoT also creates the need for petabyte scale storage of data from millions of devices. A new type of Storage is required which seamlessly integrates robust data analytics with massive scale. These storage systems will act as “smart systems” provide in-place analytics that speed discovery and enable businesses to quickly derive meaningful and actionable insights. In his session at @ThingsExpo, Paul Turner, Chief Marketing Officer at...

The Internet of Everything is re-shaping technology trends–moving away from “request/response” architecture to an “always-on” Streaming Web where data is in constant motion and secure, reliable communication is an absolute necessity. As more and more THINGS go online, the challenges that developers will need to address will only increase exponentially. In his session at @ThingsExpo, Todd Greene, Founder & CEO of PubNub, exploreed the current state of IoT connectivity and review key trends and technology requirements that will drive the Internet of Things from hype to reality.
Two weeks ago (November 3-5), I attended the Cloud Expo Silicon Valley as a speaker, where I presented on the security and privacy due diligence requirements for cloud solutions. Cloud security is a topical issue for every CIO, CISO, and technology buyer. Decision-makers are always looking for insights on how to mitigate the security risks of implementing and using cloud solutions. Based on the presentation topics covered at the conference, as well as the general discussions heard between sessions, I wanted to share some of my observations on emerging trends. As cyber security serves as a fou...
Continuous processes around the development and deployment of applications are both impacted by -- and a benefit to -- the Internet of Things trend. To help better understand the relationship between DevOps and a plethora of new end-devices and data please welcome Gary Gruver, consultant, author and a former IT executive who has led many large-scale IT transformation projects, and John Jeremiah, Technology Evangelist at Hewlett Packard Enterprise (HPE), on Twitter at @j_jeremiah. The discussion is moderated by me, Dana Gardner, Principal Analyst at Interarbor Solutions.
Too often with compelling new technologies market participants become overly enamored with that attractiveness of the technology and neglect underlying business drivers. This tendency, what some call the “newest shiny object syndrome” is understandable given that virtually all of us are heavily engaged in technology. But it is also mistaken. Without concrete business cases driving its deployment, IoT, like many other technologies before it, will fade into obscurity.
With all the incredible momentum behind the Internet of Things (IoT) industry, it is easy to forget that not a single CEO wakes up and wonders if “my IoT is broken.” What they wonder is if they are making the right decisions to do all they can to increase revenue, decrease costs, and improve customer experience – effectively the same challenges they have always had in growing their business. The exciting thing about the IoT industry is now these decisions can be better, faster, and smarter. Now all corporate assets – people, objects, and spaces – can share information about themselves and thei...
The Internet of Things is clearly many things: data collection and analytics, wearables, Smart Grids and Smart Cities, the Industrial Internet, and more. Cool platforms like Arduino, Raspberry Pi, Intel's Galileo and Edison, and a diverse world of sensors are making the IoT a great toy box for developers in all these areas. In this Power Panel at @ThingsExpo, moderated by Conference Chair Roger Strukhoff, panelists discussed what things are the most important, which will have the most profound effect on the world, and what should we expect to see over the next couple of years.
Growth hacking is common for startups to make unheard-of progress in building their business. Career Hacks can help Geek Girls and those who support them (yes, that's you too, Dad!) to excel in this typically male-dominated world. Get ready to learn the facts: Is there a bias against women in the tech / developer communities? Why are women 50% of the workforce, but hold only 24% of the STEM or IT positions? Some beginnings of what to do about it! In her Day 2 Keynote at 17th Cloud Expo, Sandy Carter, IBM General Manager Cloud Ecosystem and Developers, and a Social Business Evangelist, wil...

Discussions of cloud computing have evolved in recent years from a focus on specific types of cloud, to a world of hybrid cloud, and to a world dominated by the APIs that make today's multi-cloud environments and hybrid clouds possible. In this Power Panel at 17th Cloud Expo, moderated by Conference Chair Roger Strukhoff, panelists addressed the importance of customers being able to use the specific technologies they need, through environments and ecosystems that expose their APIs to make true change and transformation possible.
Microservices are a very exciting architectural approach that many organizations are looking to as a way to accelerate innovation. Microservices promise to allow teams to move away from monolithic "ball of mud" systems, but the reality is that, in the vast majority of organizations, different projects and technologies will continue to be developed at different speeds. How to handle the dependencies between these disparate systems with different iteration cycles? Consider the "canoncial problem" in this scenario: microservice A (releases daily) depends on a couple of additions to backend B (re...
I recently attended and was a speaker at the 4th International Internet of @ThingsExpo at the Santa Clara Convention Center. I also had the opportunity to attend this event last year and I wrote a blog from that show talking about how the “Enterprise Impact of IoT” was a key theme of last year’s show. I was curious to see if the same theme would still resonate 365 days later and what, if any, changes I would see in the content presented.
