with four Omni-Path connections Production of Omni-Path products started in 2015 and 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. First models of that series were available starting in 2015. 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 Technology,
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. Intel offered their Omni-Path products and components via other (hardware) vendors. For example, Dell EMC offered Intel Omni-Path as
Dell Networking H-series, following the naming-standard of
Dell Networking in 2017. In July 2019, Intel announced it would 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. In 2021, Cornelis announced Omni-Path Express, which replaces PSM2-based drivers and middleware, which trace back to
PathScale's PSM created in 2003, for the existing Omni-Path hardware, with a native
libfabric provider. == See also ==
