Network-Led Application Acceleration for AI and HPC
Built for Scale and Efficiency
The CN5000 Switch delivers lossless, congestion-free networking at scale, supporting up to 500,000 endpoints through key architectural features: credit-based flow control, link-level retransmissions, fabriclevel congestion management, and multipath routing without in-order delivery constraints. These innovations ensure low tail latency, eliminate packet loss, and drive higher compute utilization and lower TCO.
Optimized for AI and HPC Workloads
The CN5000 Switch delivers 400G of bandwidth per port and is purpose-built for AI training, inference, and large-scale HPC performance demands.
It provides ultra-low latency and congestion-free throughput, accelerating time-to-results for generative and agentic AI workloads. With exceptional efficiency and architectural robustness, CN5000 switches are the ideal fabric for parallelized compute environments and mission-critical HPC applications.
Reliability, Adaptability, and Efficiency
Consistent, reliable network performance is critical for AI and HPC applications. The CN5000 Switch enhances system-wide efficiency with advanced error correction and dynamic workloadaware traffic management, ensuring adaptability to changing communication patterns and sustained performance under load.
Advanced Telemetry for Intelligent Network Management
Equipped with cutting-edge telemetry capabilities, the CN5000 Switch provides real-time network insights and fine-grained visibility to optimize workload performance.
By continuously analyzing traffic patterns, identifying congestion points, and dynamically adjusting network flows, it ensures smooth, high-efficiency operation-even in the most complex compute environments.
With industry-leading precision network intelligence, CN5000 Switches enable greater control, efficiency, and performance across any scale.
In contrast to RoCEv2 and legacy InfiniBand implementations, the CN5000 switch delivers lossless, congestion-free networking that scales with the demands of AI and HPC clusters.
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.
