A few years ago, Intel introduced the high-performance Omni-Path switching architecture. It allows you to transfer data at a speed of 100 Gb / s to one port, which ultimately gives 25 GB / s of interface bandwidth.
Omni-Path was used by Intel, including in processors, and such CPUs look very funny, since they have an additional connector. However, it seems that Intel decided to abandon this technology.
The company reportedly discontinued the release of Xeon Scalable server processors with Omni-Path support. Customers can make their last orders until April 24, 2020.
Apparently, Intel will further promote switching technologies based on Ethernet and silicon photonics.
