NVIDIA Spectrum-4 SN5600 64-port 800GbE Ethernet Switch

The NVIDIA Spectrum-4 SN5600 is a 64-port 800GbE Ethernet switch engineered for next-generation AI and high-performance computing fabrics. Built on Mellanox's Spectrum-4 ASIC architecture, it delivers 51.2 Tbps of throughput with non-blocking, cut-through switching performance optimized for ultra-low latency inter-pod communication and distributed training workloads.

The SN5600 supports advanced congestion management, in-network computing capabilities, and telemetry features essential for large-scale AI cluster orchestration. Its modular port configuration and support for 800GbE optical modules enable seamless fabric scaling across multi-cabinet deployments while maintaining deterministic performance characteristics required by gradient synchronization and collective communication patterns in transformer model training.

Designed for enterprise data centers pursuing AI infrastructure modernization, the switch integrates NVIDIA Cumulus Linux for open-standard network operations and supports comprehensive monitoring through NVIDIA Mellanox Onyx firmware, enabling infrastructure-as-code deployment and programmatic fabric management across heterogeneous GPU and CPU compute clusters.

Ideal for

• Large-scale distributed AI model training with multi-node GPU clusters requiring ultra-low-latency all-reduce operations
• High-bandwidth inter-pod networking for foundation model training spanning hundreds of accelerators
• Enterprise inference serving fabric connecting inference engines with sub-millisecond tail latency requirements
• High-frequency financial data center interconnect for correlated compute and storage workloads
• Scientific computing clusters performing real-time simulation and analysis with deterministic performance SLAs
• Disaggregated storage and compute architectures requiring consistent bandwidth for distributed file systems
