Omni-Path

Omni-Path (also Omni-Path Architecture, abbr. OPA) was a high-performance communication architecture owned by Intel. It aims for low communication latency, low power consumption and a high throughput. Intel planned to develop technology based on this architecture for exascale computing. In 2017, Intel was offering at least 7 variations of multi-port Ethernet switches using this term in the form "Intel® Omni-Path Edge Switch 100 Series" all "supporting 100 Gb/s for all ports". First models of that series were already available starting Q4/2015.
History.
Production of Omni-Path products started in 2015 and mass delivery of these products started in the first quarter of 2016. In November 2015, adapters based on the 2-port "Wolf River" ASIC were announced, using QSFP28 connectors with channel speeds up to 100 Gbit/s. Simultaneously, switches based on the 48-port "Prairie River" ASIC were announced.
In April 2016, implementation of the InfiniBand "verbs" interface for the Omni-Path fabric was discussed.
In October 2016, IBM, Hewlett Packard Enterprise, Dell, Lenovo, Samsung, Seagate Technology, Micron, Western Digital and SK Hynix announced a joint consortium called Gen-Z to develop an open specification and architecture for non-volatile storage and memory products—including Intel's 3D Xpoint technology—which might in part compete against Omni-Path.
In July 2019, it was announced that Intel will not continue development of Omni-Path networks and canceled OPA 200 series (200-Gbps variant of Omni-Path).
In September 2020, Intel announced that the Omni-Path network products and technology would be spun out into a new venture with Cornelis Networks. Intel would continue to maintain support for legacy Omni-Path products, while Cornelis Networks continues the product line, leveraging existing Intel intellectual property related to Omni-Path architecture.
OEM availability.
Intel also offered their Omni-Path products and components via other (hardware) vendors so customers can get all support for their environment from a single vendor. For example, Dell EMC offers the Intel Omni-Path solution as "Dell Networking H-series", following the familiar naming-standard of Dell Networking.
