MSN3420-CB2FO, Mellanox Spectrum-2 Switch, 48xSFP28/12xQSFP28/2xAC PSU

The Mellanox NVIDIA Mellanox MSN3420-CB2FO is a top-tier enterprise switch engineered for organizations seeking flexible, high-performance networking. This Open Ethernet switch is crafted to handle intensive workloads in modern data centers and high-density enterprise environments. It enables seamless scaling through industry-leading throughput and next-generation architecture. As an NVIDIA Mellanox switch, it supports advanced network designs by integrating extensive 25GbE SFP and 100GbE QSFP connectivity, maximizing I/O options and port density for converged infrastructures. This switch powers mission-critical applications by leveraging the efficiency of 25GbE SFP interfaces, ensuring high bandwidth with low latency for demanding server aggregation or horizontal scaling requirements. For backbone and spine-leaf architectures, the 100GbE QSFP ports provide rapid core connectivity, streamlining traffic between racks and simplifying bandwidth upgrades. Open Ethernet support ensures vendor-agnostic programmability, ideal for hyperscale, multivendor, or cloud-oriented deployments across Asian, European, African, and North American markets. Robust environmental adaptability—including operational tolerance from 0°C to 40°C and up to 3,050 meters maximum altitude—guarantees reliable performance in varied global settings. Comprehensive certifications address regional compliance needs, while energy efficiency and server-class compute components (Intel x86 CPU, ample memory, and SSD storage) enable effortless virtualization and network services hosting. Whether for distributors, small to mid-sized integrators, or end users looking to future-proof their networks, the NVIDIA Mellanox MSN3420-CB2FO is a cornerstone of scalable, reliable, and application-ready switching infrastructure.
