New InfiniBand Specification Updates Expand Interoperability, Flexibility, and Virtualization Support

November 29th, 2016

Performance demands continue to evolve in High Performance Computing (HPC) and enterprise cloud networks, increasing the need for enhancements to InfiniBand capabilities, support features, and overall interoperability. To address this need, the InfiniBand Trade Association (IBTA) is announcing the public availability of two new InfiniBand Architecture Specification updates - the Volume 2 Release 1.3.1 and a Virtualization Annex to Volume 1 Release 1.3.

The Volume 2 Release 1.3.1 adds flexible performance enhancements to InfiniBand-based networks. With the addition of Forward Error Correction (FEC) upgrades, IT managers can experience both minimal error rates and low latency performance. The new release also enables the InfiniBand subnet manager to optimize signal integrity while maintaining the lowest power possible from the port. Additionally, updates to QSFP28 and CXP28 memory mapping support improved InfiniBand cable management.

This new Volume 2 release also improves upon interoperability and test methodologies for the latest InfiniBand data rates, namely EDR 100 Gb/s and FDR 56 Gb/s. These enhancements are achieved through updated EDR electrical requirements, amended testing methodology for EDR Limiting Active Cables, and FDR interoperability and test specification corrections.

With an aim toward supporting the ever-increasing deployment of virtualized solutions in HPC and enterprise cloud networks, the IBTA also published a new Virtualization Annex to Volume 1 Release 1.3. The Annex extends the InfiniBand specification to address multiple virtual machines connected to a single physical port, which allows subnet managers to recognize each logical endpoint and reduces the burden on the subnet managers as networks leverage virtualization for greater system scalability.

The InfiniBand Architecture Specification Volume 2 Release 1.3.1 and Volume 1 Release 1.3 are available for public download here.

IBTA Updates HPC Community on the Continued Evolution of InfiniBand at SC16

November 14th, 2016

Starting this week, the international supercomputing community will gather in Salt Lake City, Utah for the Supercomputing Conference 2016 (SC16). The event includes six days of timely and informative presentations, papers, tutorials, research posters, exhibits and Birds-of-a-Feather sessions. SC16 gives scientists, engineers, researchers, educators, programmers, system administrators and developers the opportunity to learn about innovative technologies that will shape the future of large-scale technical computing and data-driven research.

IBTA members will be in full force at the show again this year to promote our organization’s mission and showcase their InfiniBand and RoCE solutions. In addition, visit any of the following exhibits during SC16 to learn more about InfiniBand-based technologies and see a wide-variety of offerings up close:

• Broadcom (#3677)
• Bull (#721)
• Cray (#1731)
• Dell EMC (#2209)
• DDN Storage (#1931)
• Ethernet Alliance (#1101)
• Finisar (#706)
• Fujitsu Limited (#831)
• Hewlett Packard Enterprise (#1531)
• IBM (#1018 and #1042)
• Lenovo (#2643) • Mangstor, Inc. (#3377)
• Mellanox (#2631)
• Microsoft (#1501)
• Molex (#1947)
• NVIDIA (#2217 & #2231)
• Oracle (#1231)
• RSC Group (#3818)
• Samtec (#2522)
• Seagate (#1209)
• SGI (#1519)
• Supermicro (#1717)

The Future is Bright for InfiniBand and Students of HPC

With a robust ecosystem and an aggressive roadmap for performance increases, the IBTA believes InfiniBand technology will play a vital role in building the future of supercomputing. That said, we expect InfiniBand will make an appearance during the Student Cluster Competition (SCC), a 48-hour challenge where students from all around the world demonstrate the skills, technologies and science needed to build, maintain and utilize a supercomputer. This competition not only highlights each student’s technical expertise but also introduces the next generation of engineers to the HPC community overall. Keep an eye out for IBTA representatives at SCC who will be meeting with the students and getting them thinking about InfiniBand technology through IBTA-branded giveaways.

Additionally, the IBTA will be providing updates to attending press and analysts on recent developments and upcoming enhancements to the InfiniBand Architecture Specification. Interested media or analysts can contact press@infinbandta.org to schedule briefings.
