Cornelis Networks

What Cornelis Networks does

Cornelis Networks is a privately held U.S. semiconductor and networking company that designs and sells high-performance interconnect fabrics — adapters (SuperNICs), switches, director-class switches, and cabling — purpose-built for artificial intelligence training/inference workloads and high-performance computing. The company was established in 2020 as an Intel spinout after acquiring the Omni-Path intellectual property when Intel discontinued that product line, and it operates from Wayne, Pennsylvania under CEO Lisa Spelman, a former Intel Xeon executive appointed in August 2024. Its portfolio centers on the CN5000 family, a 400G lossless and congestion-free scale-out fabric, and the announced CN6000, an 800G multi-protocol SuperNIC supporting Omni-Path, RoCEv2, and Ultra Ethernet on PCIe 6.0, with a legacy Omni-Path 100 line maintained via the Omni-Path Express software stack. Cornelis OPX, the host and management software for CN5000, is distributed as open source.

The company's revenue model is built on hardware sales (SuperNICs, switches, and cables) supplemented by recurring software revenue from OPX subscriptions and the Accelerated Host Fabric Suite for Omni-Path 100. Approximately 50% of revenue is generated through channel partners, supported by three authorized distributors (ASI, Ingram Micro, TD Synnex), 26 channel and OEM partners, and federal integrators CTG Federal and TVAR Solutions. Named deployments include the 952-node Lynx supercomputer at Lawrence Livermore National Laboratory for DOE/NNSA missions, a 600-plus-node CN5000 upgrade to TACC's Stampede3 system serving over 5,000 researchers, and federal AI/HPC deployments at NASA, DHS, and DoD. The company has raised approximately $93M-plus across four disclosed funding rounds since 2020 and competes primarily against Nvidia InfiniBand, which holds an estimated 51% of the HPC networking market versus Cornelis' roughly 3% share.

Core offering

Cornelis Networks designs and sells purpose-built high-performance networking fabrics for AI and HPC workloads. Its core offering is the Omni-Path-based CN5000 (400G) and upcoming CN6000 (800G) product families, comprising SuperNIC adapters, switches, director-class switches, and cables, bundled with open-source host fabric management software (Cornelis OPX). The fabrics deliver lossless, congestion-free connectivity for government, research, and enterprise HPC/AI clusters.

Product overview

Cornelis Networks offers a portfolio of high-performance networking solutions for AI and HPC workloads. The product lineup consists of two main families: the newer CN6000 (800G, multi-protocol SuperNIC supporting Omni-Path, RoCEv2, and Ultra Ethernet on PCIe 6.0) and the established CN5000 (400G lossless, congestion-free network). Both families include SuperNICs, switches, director class switches, and cables. The legacy Omni-Path 100 series provides lower-end HPC solutions using Omni-Path Express. All products share a common architecture built on Omni-Path intellectual property acquired from Intel in 2020. Supporting software includes Cornelis OPX (open-source host and management software) for CN5000 and the Accelerated Host Fabric Suite for Omni-Path 100.
