CN5000 Omni-Path® Director Class Switch

Revolutionizing AI & HPC Infrastructure with 400G Ultra-Dense Networking for Scalable Acceleration

Purpose-Built for Massive Scale and Density

The CN5000 Director Class Switch (DCS) enables exascale compute fabrics by consolidating network connectivity in a single, high-density chassis.

With support for thousands of nodes through fewer switch tiers, this 576- port powerhouse reduces cabling complexity, improves reliability, and drives down latency. This means fewer switches, fewer hops, and fewer points of failure—all while achieving unmatched scale with uncompromised efficiency.

Optimized for AI and HPC at Unprecedented Scale

As AI training sets and HPC simulations continue to scale, network infrastructure must evolve to support exponentially growing data flows without compromise.

The CN5000 DCS delivers consistent ultra-low latency and maximum throughput. Its high port count allows for flatter, more efficient topologies— ideal for GPU-heavy workloads, multinode AI pipelines, and tightly coupled HPC simulations. This means faster time-to-results and more effective use of compute resources.

Lower TCO Through Intelligent Consolidation

With up to 576-ports per switch, the CN5000 DCS reduces the need for extensive switching infrastructure, lowering capital expenditures, power consumption, and operational complexity. Intelligent traffic flow management and congestion control ensure efficient resource utilization and extend the longevity of your infrastructure investments.

Built-In Reliability, Resilience and Flexibility

Designed for always-on, missioncritical deployments, the CN5000 DCS offers enterprise-class resilience and operational continuity. With built-in error correction, redundant hot-swappable power supplies and cooling modules, fault tolerance, and dynamic network function allocation, the CN5000 DCS ensures consistent, highavailability operation. Its adaptability across diverse workloads makes it a strategic backbone for evolving compute demands—whether you are running complex AI models, fluid dynamics simulations, or large-scale genomics pipelines.

Industry-Leading Telemetry for Scalable Intelligence

At massive scale, network visibility is not optional, it is essential. The CN5000 DCS delivers fine-grained telemetry and real-time traffic analytics to detect congestion, rebalance workloads, and optimize performance. These capabilities scale with infrastructure growth, providing actionable insights and proactive control across thousands of endpoints.

Omni-Path Architecture

CN5000 Architecture delivers lossless and congestion-free data transmission with credit-based flow control and dynamic fine-grained adaptive routing. It is designed for maximum performance, reliability, scalability, and data integrity with dynamic lane scaling and optimized link protection.

The Cornelis CN5000 Omni-Path product family includes the Switch, Director Class Switch, and SuperNIC; cables; and open-source Host and Management OPX Software all offering flexible, high-performance networking solutions for diverse infrastructure needs.
