NVIDIA MSN3700-VS2FC | Spectrum-2 32-Port 200G Switch, 12.8Tbps, Cumulus Linux

Q: What speeds are supported on each QSFP56 port?
A: Each QSFP56 port on the MSN3700-VS2FC supports flexible port speeds spanning 10GbE, 25GbE, 40GbE, 50GbE, 100GbE, and 200GbE. Ports are fully splittable using breakout cables, allowing maximum deployment flexibility for spine, super-spine, and high-density leaf configurations.

Q: What is Cumulus Linux and how does it benefit network operations?
A: Cumulus Linux is an open network operating system based on Debian Linux. It provides native Linux networking with advanced automation, programmability via tools like Ansible and Puppet, and support for modern protocols including VXLAN, EVPN, BGP, and OSPF. This enables DevOps-style workflows and integration with cloud-native infrastructure.

Q: Can this switch be used in leaf-spine architectures?
A: Yes, the MSN3700-VS2FC is designed primarily as a spine or super-spine switch for large-scale data center fabrics. With 12.8Tbps of throughput and support for speeds from 10GbE to 200GbE, it provides full rack connectivity and flexible blocking ratios for leaf-spine and Clos network topologies.

Q: What telemetry and visibility features are available?
A: The Spectrum-2 ASIC supports advanced telemetry features including NVIDIA What Just Happened (WJH) for real-time troubleshooting, hardware-accelerated histograms for queue depth tracking, Inband Network Telemetry (INT) readiness, streaming telemetry, and over 512K on-chip flow counters for deep network visibility.

Q: Is the MSN3700-VS2FC suitable for AI and machine learning workloads?
A: Yes, with 200GbE port density, ultra-low 425ns latency, and a fully shared 42MB packet buffer, the MSN3700-VS2FC is well-suited for high-bandwidth, low-latency applications such as AI training clusters, GPU compute fabrics, machine learning infrastructure, and hyperconverged storage environments.
