SR004: Assessment and Ranking of Major Interconnect Vendor Offerings

Assessment and Ranking of Major Interconnect Vendor Offerings

From a market share perspective, the HPI market is currently led by: InfiniBand and Ethernet, followed by proprietary offerings from HPC vendors such as Cray and SGI, and the newly introduced Omni-Path Architecture (OPA) from Intel.

As a proxy for the HPI market segment, the TOP500 list of the most powerful systems in the world provides a glimpse of market dynamics at the very high-end: over 40% are based on InfiniBand, 44% use Ethernet, and 15% are built with proprietary interconnects. However it is worthwhile to note that only five of the TOP100 systems are Ethernet-based, and the highest is ranked in the 74th position.
