Obsidian Welcomes Mellanox and its MetroX Product into the Long Haul InfiniBand Market

Mellanox's recent announcement at the Supercomputing 2012 event of a soon to be released product capable of extending 10Gbits/s InfiniBand fabrics over as much as 10 km has been welcomed by the market pioneer and leader, Obsidian.

The importance of range-extension for the very high performance but intrinsically short-reach InfiniBand protocol is not lost on Obsidian, which first demonstrated the capability with its Longbow products at the same Supercomputing conference seven years earlier in Seattle.

Obsidian's CVO, Dr. David Southwell recalls: “In 2005, Obsidian demonstrated three wide area InfiniBand links encapsulated inside standard SONET and ATM WAN protocols, connecting the show's internal super network - SCInet – to the Lawrence Livermore National Laboratory in California (1,300 km), Intel's HPC facility in Dupont, WA (100 km) and a cross country path to the Naval Research Laboratory in Washington, DC. While the 5,000 km link to NRL was by far the longest InfiniBand link demonstrated at that time, it was the relatively short 100 km run to Intel's Dupont facility that possibly did more to raise the awareness of the potential for long haul InfiniBand. Then Microsoft CEO Bill Gates, using partners Intel, Cisco and Obsidian, was able to make use of the high performance link during his key note address to migrate a large HPC data set to an Intel supercomputer in Dupont, allowing the results to rapidly migrate back in real time during his talk – actually an early demonstration of HPC cloud before the term had been coined.”

Dr. Southwell continued, “While Obsidian’s team of experts have gone on to develop a suite of capability sets including native InfiniBand routing, encryption/authentication, long-distance standards-based WDM devices, file migration software, diagnostic tools and more recently in collaboration with Lawrence Livermore National Laboratory and NASA Ames Research Center subnet management for compound topologies, we remain very passionate about long haul InfiniBand. We understand the demands of spanning HPC LAN and optical WAN domains in a single device, of rigorous standards compliance and carrier grade reliability. As Mellanox attempts to expand their sphere of expertise starting with stretched LANs of up to 10km with a view to stepping up to the full gambit of optical capability in the future, we wish them every success in our marketplace.”

“I can recall when Dr. Southwell and I met with Eyal several years ago to discuss incorporating long haul IB in their SDR switch,” remarked Bill Halina, Obsidian’s Chairman, “in the fast paced technology world it’s truly inspiring to see vision turn into reality and ultimately find its way into everyone’s home.”

Meet the Obsidian team at SC12 (Convention Center, Salt Lake City, UT) in booth #4052 from November 12th to 15th.

About Obsidian Strategics

Obsidian Strategics™ is the developer of Longbow™, a series of InfiniBand products featuring range extension, routing and encryption. Longbow technology allows an InfiniBand fabric, normally a short-range network used in high-performance computing, to be extended via optical fiber over varying distances. Longbow connects across Campus, Metro or Global networks to enable unparalleled real-time backup over long-distance, high-bandwidth video transmission and efficient movement of large data sets to compute and storage resources. www.obsidianstrategics.com.

A strange thing is happening along the way to the Internet of Things, namely far too many devices to work with and manage. It has become clear that we'll need much higher efficiency user experiences that can allow us to more easily and scalably work with the thousands of devices that will soon be in each of our lives. Enter the conversational interface revolution, combining bots we can literally talk with, gesture to, and even direct with our thoughts, with embedded artificial intelligence, wh...

Why do your mobile transformations need to happen today? Mobile is the strategy that enterprise transformation centers on to drive customer engagement. In his general session at @ThingsExpo, Roger Woods, Director, Mobile Product & Strategy – Adobe Marketing Cloud, covered key IoT and mobile trends that are forcing mobile transformation, key components of a solid mobile strategy and explored how brands are effectively driving mobile change throughout the enterprise.
In this strange new world where more and more power is drawn from business technology, companies are effectively straddling two paths on the road to innovation and transformation into digital enterprises. The first path is the heritage trail – with “legacy” technology forming the background. Here, extant technologies are transformed by core IT teams to provide more API-driven approaches. Legacy systems can restrict companies that are transitioning into digital enterprises. To truly become a lea...
What are the new priorities for the connected business? First: businesses need to think differently about the types of connections they will need to make – these span well beyond the traditional app to app into more modern forms of integration including SaaS integrations, mobile integrations, APIs, device integration and Big Data integration. It’s important these are unified together vs. doing them all piecemeal. Second, these types of connections need to be simple to design, adapt and configure...
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.
What happens when the different parts of a vehicle become smarter than the vehicle itself? As we move toward the era of smart everything, hundreds of entities in a vehicle that communicate with each other, the vehicle and external systems create a need for identity orchestration so that all entities work as a conglomerate. Much like an orchestra without a conductor, without the ability to secure, control, and connect the link between a vehicle’s head unit, devices, and systems and to manage the ...

The Jevons Paradox suggests that when technological advances increase efficiency of a resource, it results in an overall increase in consumption. Writing on the increased use of coal as a result of technological improvements, 19th-century economist William Stanley Jevons found that these improvements led to the development of new ways to utilize coal. In his session at 19th Cloud Expo, Mark Thiele, Chief Strategy Officer for Apcera, will compare the Jevons Paradox to modern-day enterprise IT, e...
Major trends and emerging technologies – from virtual reality and IoT, to Big Data and algorithms – are helping organizations innovate in the digital era. However, to create real business value, IT must think beyond the ‘what’ of digital transformation to the ‘how’ to harness emerging trends, innovation and disruption. Architecture is the key that underpins and ties all these efforts together. In the digital age, it’s important to invest in architecture, extend the enterprise footprint to the cl...

Data is an unusual currency; it is not restricted by the same transactional limitations as money or people. In fact, the more that you leverage your data across multiple business use cases, the more valuable it becomes to the organization. And the same can be said about the organization’s analytics. In his session at 19th Cloud Expo, Bill Schmarzo, CTO for the Big Data Practice at EMC, will introduce a methodology for capturing, enriching and sharing data (and analytics) across the organizati...
