NVIDIA Spectrum MSN3700-VS2FC 32-Port 200GbE Open Ethernet Switch

1. MSN3700-VS2FC Product Overview

The NVIDIA Spectrum MSN3700-VS2FC is a high-performance, 1U Open Ethernet switch designed for modern data center leaf and spine layers. Powered by the Spectrum-2 ASIC, it delivers 6.4 Tb/s bidirectional throughput and supports 32 QSFP56 ports capable of speeds from 10GbE to 200GbE per port. Pre-installed with Cumulus Linux, it offers flexibility, scalability, and advanced automation for cloud, enterprise, and storage networks.

2. MSN3700-VS2FC Key Characteristics

• 32 x QSFP56 ports supporting 10/25/40/50/100/200GbE speeds
• 6.4 Tb/s switching capacity with 8.33 Bpps processing
• 42 MB fully shared packet buffer for fair traffic management
• Cut-through latency as low as 425 ns
• Pre-installed Cumulus Linux for open networking and automation
• Hot-swappable power supplies and fans for high availability

3. MSN3700-VS2FC Core Technology

The switch leverages NVIDIA’s Spectrum-2 ASIC with support for VXLAN routing, IPv6 segment routing, RoCE, and hardware-accelerated telemetry via What Just Happened (WJH) technology. It also features programmable pipelines, deep packet inspection (up to 512B), and support for Docker containers and third-party applications.

4. Working Principle

The Spectrum-2 ASIC processes packets in a single pass, enabling high-speed VXLAN routing and bridging without performance degradation. The fully shared buffer ensures fair bandwidth allocation and prevents congestion. Cumulus Linux runs on top, providing a Linux-based CLI, automation tools, and integration with open networking stacks like FRR and SONiC.

5. Applications

• Data center spine and super-spine layers
• Cloud infrastructure and hyper-scale networking
• AI and machine learning clusters with RoCE support
• High-performance storage fabrics (NVMe-oF)
• Enterprise and campus core switching
