CN6000 800G Omin-Path® SuperNIC and Ethernet SuperNIC
The first multi-protocol SuperNIC unifying Omni-Path, RoCEv2, and Ultra Ethernet at 800Gbps on PCIe 6.0 — delivering the industry’s highest performance for AI and HPC at any scale.
The Network AI and HPC Has Been Waiting For
Multi-Protocol Performance Without Trade-offs
The CN6000 SuperNIC is the first adapter to simultaneously support Omni-Path, Ethernet RoCEv2, and Ultra Ethernet Compliance on a single silicon platform. Each port is independently configurable, allowing operators to run Omni-Path for maximum-performance HPC fabrics on one port and RoCEv2 or Ultra Ethernet on the other — connecting seamlessly to any 400G/800G Ethernet switch ecosystem without a forklift upgrade.
Powered by Cornelis’ production-proven pipeline architecture and a new Ethernet Adaptation Layer, CN6000 brings the performance DNA of Omni-Path — credit-based flow control, fine-grained adaptive routing, and sub-microsecond latency — to the world’s most widely deployed networking standard. The result: deterministic, congestion-free behavior in heterogeneous environments that previously required separate fabrics.
Industry-Leading Performance at Gigawatt-AI Scale
As AI factories scale toward gigawatt-class deployments, traditional Ethernet architectures buckle under collective communication pressure. The CN6000 800G SuperNIC eliminates that bottleneck. Delivering 1.6 billion messages per second — the highest in the industry — with sub- 1 μs MPI latency and 800 Gbps of bidirectional bandwidth, the SuperNIC keeps GPUs saturated and CPU clusters moving.
Ecosystem-Ready End-to-End
The CN6000 SuperNIC pairs with CN6000-series Omni-Path edge switches for a fully optimized end-to-end fabric, and interoperates with Arista, Cisco, Juniper, NVIDIA Spectrum, and other standards-based Ethernet end points. CN6000 SuperNIC is backward compatible with CN5000 infrastructure allowing customers to upgrade at their own pace.
No Compromise RoCEv2
Hardware-accelerated RDMA, lightweight queue pairs, and a RoCEv2 In-Flight tracking table enable the SuperNIC to maintain millions of concurrent operations at line rate, providing deterministic latency and throughput as cluster sizes grow from thousands to hundreds of thousands of nodes.
The result: Lower AllReduce completion time versus alternate solutions, higher GPU utilization — directly translating into faster training runs, lower power and cooling costs, and higher token yield per dollar.
Secured by Post Quantum Cryptography
Security is first-class citizen with CN6000 with a PQC-enabled Root-of-Trust with SPDM 1.4 (ML-DSA-87 + ECDSA P-384) that protects every deployment against both current and future cryptographic threats.
The SuperNIC optimizes real-time inferencing, shortens feedback loops, and reduces time-to-results. Its robust and efficient design makes it the ideal choice for highly parallelized applications at any scale.
Open and Built for Every Environment
CN6000 is designed around openness at every layer. As a founding contributor to libfabric — now the transport foundation of the Ultra Ethernet Consortium — Cornelis brings deep protocol expertise to Ultra Ethernet 1.0’s full feature set: Reliable Unordered Delivery (RUD), Reliable Ordered Delivery (ROD), and unreliable delivery modes.
The CN6000 PCIe 6.0 x16 SuperNIC also supports industry standard virtualization with SR-IOV, GPU-Direct for NVIDIA and AMD accelerators, and compatibility with PyTorch, NCCL, RCCL, UCX, MPI, and OpenFabrics ensure it integrates into any AI or HPC software stack. Air- and conduction-cooling options support the most demanding rack densities.
The Cornelis CN6000 Omni-Path product family is a flexible, high-performance end-to-end networking solution that addresses diverse infrastructure needs and is comprised of the Switch, SuperNIC, cables, and open-source OPX Host and Management Software. CN6000 is also interoperable with the CN5000 product family.
