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

IBTA Releases New Update to InfiniBand Architecture Specification

March 10th, 2015

Today, the IBTA announced Release 1.3 of the InfiniBand Architecture Specification Volume 1. Dedicated to our mission to maintain and further the specification, we worked to incorporate capabilities to help keep up with the increasing customer demand for expedited data transfer and accessibility. This effort resulted in a fresh version of the specification, which incorporates new features that enable computer systems to match the continuous high performance computing and data center needs required for increased stability and bandwidth, as well as high computing efficiency, availability and isolation.

The rapid evolution of the computer and internet have left existing interconnect technologies struggling to keep pace. The increasing popularity of high-end computing concepts like clustering, CPU offloads and movement of large amounts of data demand a robust fabric.

Additionally, I/O devices are now expected to have link-level data protection, traffic isolation, deterministic behavior and a high quality of service. In order to help meet these needs, the IBTA developed InfiniBand Architecture (IBA) in 2000 and has continued to update the specification suite as the industry evolves.

As a result of this initiative, the updated Volume 1.3 enables notable improvements in scalability with deeper visibility into switch-fabric configuration for improved monitoring of traffic patterns and network maintenance. The updated specification allows for more in-depth cable management with greater accessibility to cables for improved diagnostics mechanisms allowing for shorter response times and improved messaging capabilities, thus improving overall network performance.
