InfiniBand Volume 1, Release 1.3 – The Industry Sounds Off

May 14th, 2015


On March 10, 2015, IBTA announced the availability of Release 1.3 of Volume 1 of the InfiniBand Architecture Specification and it’s creating a lot of buzz in the industry. IBTA members recognized that as compute clusters and data centers grew larger and more complex, the network equipment architecture would have difficulty keeping pace with the need for more processing power. With that in mind, the new release included improvements to scalability and management for both high performance computing and enterprise data centers.

Here’s a snap shot of what industry experts and media have said about the new specification:

“Release 1.3 of the Volume 1 InfiniBand Architecture Specification provides several improvements, including deeper visibility into switch hierarchy, improved diagnostics allowing for faster response times to connectivity problems, enhanced network statistics, and added counters for Enhanced Data Rate (EDR) to improve network management. These features will allow network administrators to more easily install, maintain, and optimize very large InfiniBand clusters.” - Kurt Yamamoto, Tom’s IT PRO

“It’s worth keeping up with [InfiniBand], as it clearly shows where the broader networking market is capable of going… Maybe geeky stuff, but it allows [InfiniBand] to keep up with “exascales” of data and lead the way large scale-out computer networking gets done. This is particularly important as the 1000 node clusters of today grow towards the 10,000 node clusters of tomorrow.” - Mike Matchett, Taneja Group, Inc.

“Indeed, a rising tide lifts all boats, and the InfiniBand community does not intend to get caught in the shallows of the Big Data surge. The InfiniBand Trade Association recently issued Release 1.3 of Volume I of the format’s reference architecture, designed to incorporate increased scalability, efficiency, availability and other functions that are becoming central to modern data infrastructure.” - Arthur Cole, Enterprise Networking Planet

“The InifiniBand Trade Association (IBTA) hopes to ward off the risk of an Ethernet invasion in the ranks of HPC users with a renewed focus on manageability and visibility. Such features have just appeared in release 1.3 of the Volume 1 standard. The IBTA’s Bill Lee told The Register that as HPC clusters grow, ‘you want to be able to see every level of switch interconnect, so you can identify choke-points and work around them.’” - Richard Chirgwin, The Register

Observations from SC12

December 3rd, 2012

The week of Supercomputing went by quickly and resulted in many interesting discussions around supercomputing and its role in both HPC environments and enterprise data centers. Now that we’re back to work, we’d like to reflect back on the successful supercomputing event. The conference this year saw a huge diversity of attendees from various countries, with major participation from top universities, which seemed to be on the leading edge of Remote Direct Memory Access (RDMA) and InfiniBand deployments.

Overall, we saw InfiniBand and Open Fabrics technologies continue their strong presence at the conference. InfiniBand dominated the Top500 list and is still the #1 interconnect of choice for the world’s fastest supercomputers. The Top500 list also demonstrated that InfiniBand is leading the way to efficient computing, which not only benefits high performance computing, but enterprise data center environments as well.

We also engaged in several discussions around RDMA. Attendees, analysts specifically, were interested in new products using RDMA over Converged Ethernet (RoCE) and their availability, and were impressed that Microsoft Server 2012 natively supports all three RDMA transports, including InfiniBand and RoCE. Another interesting development is InfiniBand customer Microsoft Windows Azure, and their increased efficiency placing them at 165 on the Top500 list.

IBTA & OFA Booth at SC12

IBTA’s release of the new InfiniBand Architecture Specification 1.3 generated a lot of buzz among attendees, press and analysts. IBTA’s Electro-Mechanical Working Group Chair, Alan Benner, was one of our experts at the booth and drew a large crowd of people interested in the InfiniBand roadmap and his projections around the availability of the next specification, which is expected to include EDR and become available in draft form in April 2013.

SC12 provides a great opportunity those in high performance computing to connect in person and engage in discussions around hot industry topics; this year was focused on Software Defined Networking (SDN), OpenSM, and the pioneering efforts by both IBTA and OFA. We enjoyed conversations with exhibitors and attendees that visited our booth and a special thank you to all of those RDMA experts who participated in our booth session: Bill Boas, Cray; Katharine Schmidtke, Finisar; Alan Brenner, IBM; Todd Wilde, Mellanox; Rupert Dance, Software Forge; Kevin Moran, System Fabric Works; and Josh Simons, VMware.

New InfiniBand Architecture Specification Open for Comments

October 15th, 2012

After an extensive review process, Release 1.3 of Volume 2 of the InfiniBand Architecture Specification has been approved by our Electro-Mechanical Working Group (EWG). The specification is undergoing final review by the full InfiniBand Trade Association (IBTA) membership and will be available for vendors at Plugfest 22, taking place October 15-26, 2012 at University of New Hampshire Interoperability Lab in Durham, New Hampshire.

All IBTA working groups and individual members have had several weeks to review and comment on the specification. We are encouraged by the feedback we’ve received and are looking forward to the official release at SC12, taking place November 10-16 in Salt Lake City, Utah.

Release 1.3 is a major overhaul of the InfiniBand Architecture Specification and features important new architectural elements:
• FDR and EDR signal specification methodologies
• Analog signal specifications for FDR, that have been verified through Plugfest compliance and interoperability measurements
• More efficient 64b/66 encoding method
• Forward Error Correction coding
• Improved specification of QSFP-4x and CXP-12x connectors, ports and management interfaces

The new specification also includes significant copy editing and organization to include sub volumes and improve overall readability. The previous specification, Release 1.2.1, was released in November 2007. As Chair of the EWG, I’m pleased with the technical progress made on the InfiniBand Architecture specification. More importantly, I’m excited about the impact that this new specification release will have for users and developers of InfiniBand technology.
