Intel abandons its 200Gbps Omni-Path networking fabric architecture
Is this the end or a new beginning?

Why it matters: Data might be all the rage these days, but apparently, Intel didn’t get the memo. Since 2015 Intel and their Omni-Path architecture have competed with Mellanox for dominance in datacenter networking, with Intel capturing 10% of the top 500 supercomputers and Mellanox 25%. Until recently speeds were capped at 100Gbps, but Mellanox has upped the ante with 200Gbps, and Intel would rather back down than compete.

Despite Omni-Path continuing to be a popular solution – according to Intel, at least – several of Intel’s largest customers told CRN that Intel will be ending production of OPA100 (Omni-Path Architecture 100Gbps) soon, and only manufacturing on request.
Omni-Path is a competing solution to Ethernet and InfiniBand, though Intel sells products using all three standards.

Mellanox, recently purchased by Nvidia and one Intel’s main competitor, uses InfiniBand and Ethernet.
While Intel’s exit from the market seems worrying (we’ve all seen what happens when Nvidia gets a monopoly), it could be a sign that they’re doubling down on their InfiniBand and ethernet products. [...] in April they demoed a version operating at 400Gbps.

“We are evaluating options for extending the capabilities for high-performance ethernet switches that we can expand the ability to meet the growing needs of HPC and AI. More to come.”

Intel spins out omni-path interconnect business

Intel’s Omni-Path Architecture high-speed interconnect technology is getting a second life under a stand-alone company that has spun out from the chipmaker and raised US$20 million in venture capital, giving partners once again an alternative to Mellanox’s InfiniBand that is now owned by Nvidia.

The new company, Cornelis Networks, came out of stealth mode and announced its Series A funding round Wednesday, [...] The round’s other investors were Chestnut Street Ventures and Intel Capital, the chipmaker’s venture arm.

CRN reported more than a year ago that Intel had halted development for its second-generation, 200-Gbps version of Omni-Path Architecture while pledging that it would continue to sell and support the first-generation, 100-Gbps products, giving partners little incentive to continue investing in the technology. The move was a boon for Mellanox Technologies, which was already shipping a 200-Gbps version of its InfiniBand interconnect and was in the process of getting acquired by Nvidia.

“It started becoming apparent to me that Intel was going to de-emphasize this product line. And I spent the bulk of my career working on it, and I could see that it still had very big potential,” he said.

However, the executive said, Cornelis still has a lot of potential as a stand-alone company and could see the sort of growth that could give Intel second thoughts on divesting.
