NVIDIA Mellanox MSN3700-CS2F 32-Port 100GbE QSFP28 Spectrum-2 Open Ethernet Switch with Onyx OS: This is a 1U managed Layer 2/3 Ethernet switch built on the NVIDIA Spectrum-2 ASIC, equipped with 32 QSFP28 ports for 100Gb/s Ethernet aggregation. The unit ships with Mellanox Onyx OS and uses P2C (Power-to-Connector) airflow. This is a fixed-port fixed-form-factor switch chassis, not a modular line card. This is a brand new unit (NVIDIA P/N: 920-9N201-00F7-0X0).
Engineering Context
The MSN3700-CS2F uses the Spectrum-2 ASIC with up to 6.4 Tb/s of switching capacity. The 32 QSFP28 ports each operate natively at 100GbE, with optional breakout to 2x50GbE or 4x25GbE per port using QSFP28 breakout cables. P2C airflow (Power-to-Connector) suits cold-aisle-front data center layouts. Dual hot-swappable AC power supplies provide N+N redundancy. Onyx OS provides a fully managed L2/L3 stack with BGP, OSPF, MLAG, VXLAN/EVPN, telemetry, and a CLI/REST/gNMI management interface.
Deployment & Use Cases
Spine and leaf positions in 100GbE Ethernet fabrics. AI/ML compute cluster east-west networks. Cloud and hyperscaler aggregation. Enterprise core 100GbE deployments. Storage backbones for NVMe-over-Fabrics and distributed file systems. Carrier and service-provider edge.
