Product Description

NVIDIA Spectrum SN3000 Series MSN3700-CS2F 100GbE Open Ethernet Switch

1. Product Overview

The NVIDIA Spectrum SN3000 Series MSN3700-CS2F is a high-performance, 1U open Ethernet switch designed for modern data center leaf and spine deployments. Built on the Spectrum-2 ASIC, it delivers 6.4 Tb/s bidirectional throughput with 32x 100GbE QSFP28 ports. It supports multiple network operating systems including NVIDIA Onyx®, Cumulus Linux®, and ONIE-enabled options, providing flexibility and avoiding vendor lock-in. This network switch is ideal for cloud, enterprise, and high-performance computing environments.

2. Key Characteristics

  • 32 x 100GbE QSFP28 ports, splittable to 128 x 10/25GbE
  • 6.4 Tb/s switching capacity, 4.76 Bpps forwarding rate
  • 42 MB fully shared packet buffer
  • Cut-through latency as low as 425 ns
  • Support for multiple NOS: NVIDIA Onyx, Cumulus Linux, SONIC, ONIE
  • Hardware Root of Trust (HRoT) for secure boot (on -S models)
  • 1+1 redundant hot-swappable power supplies, N+1 fans

3. Core Technologies

The SN 2000 series successor, the SN3000 leverages NVIDIA’s Spectrum-2 ASIC with support for:

  • VXLAN routing and bridging
  • RoCE (RDMA over Converged Ethernet)
  • In-band network telemetry (INT) and NVIDIA WJH®
  • IPv6 Segment Routing
  • 512K flow counters and ACL scale
  • Docker container support for on-switch applications

4. Working Principle

The network switch operates at wire speed using a fully shared packet buffer architecture. It supports cut-through forwarding to minimize latency. The programmable pipeline allows deep packet inspection (up to 512B) and supports advanced tunneling and encapsulation protocols. The switch can be managed via standard CLI, REST APIs, or integrated with NVIDIA Cumulus NetQ for real-time visibility and automation.

5. Applications

  • Data center leaf/spine architectures
  • High-performance computing (HPC) and AI clusters
  • Cloud infrastructure and hyper-converged systems
  • Financial trading and low-latency networks
  • Media and entertainment data fabrics
