NVIDIA Spectrum SN3000 MSN3700-CS2F: High-Density 100GbE Open Networking Switch

1. Product Overview

The MSN3700-CS2F is a 1U form factor network switch from NVIDIA's Spectrum SN3000 series, delivering 32 ports of 100GbE connectivity with the flexibility to split ports for 10/25GbE server connections. Built on the Spectrum-2 ASIC architecture, this open Ethernet switch provides 6.4Tb/s of non-blocking throughput, making it an ideal solution for modern data center spine and leaf deployments. With support for multiple operating systems including NVIDIA Onyx, this network switch offers unparalleled flexibility and performance for cloud, enterprise, and high-performance computing environments.

2. Key Features

• 32 x QSFP28 ports supporting 100GbE, 50GbE, 40GbE, and 25GbE speeds
• Port splitting capability to support up to 128 x 10/25GbE connections
• 6.4Tb/s switching capacity with 4.76 billion packets per second forwarding rate
• Cut-through switching with consistent 425ns latency
• 42MB fully shared packet buffer for burst absorption
• Dual hot-swappable power supplies (AC) with N+1 fan redundancy
• Pre-installed with NVIDIA Onyx network operating system

3. Advanced Technologies

The SN3000 series incorporates NVIDIA's Spectrum-2 ASIC with support for:

• RoCE (RDMA over Converged Ethernet) for GPU-direct networking
• VXLAN routing and bridging with hardware acceleration
• Advanced telemetry with What Just Happened (WJH) technology
• In-band network telemetry (INT) for real-time monitoring
• Programmable pipeline with deep packet inspection (up to 512 bytes)
• Open Ethernet standards including ONIE for network operating system flexibility

4. Operational Architecture

The MSN3700-CS2F utilizes a fully shared packet buffer architecture that dynamically allocates memory across all ports, ensuring fair bandwidth distribution and preventing head-of-line blocking. The switch operates in cut-through mode, forwarding packets immediately after the header is processed without storing the entire frame. This approach minimizes latency while maintaining line-rate performance. The Spectrum-2 ASIC processes packets in a single pass, even for complex operations like VXLAN routing and network address translation.

5. Deployment Scenarios

• Data center spine layer supporting 100GbE fabric connectivity
• High-density leaf switch for 25GbE server connectivity
• AI/ML cluster networking with RoCE support for NVIDIA GPUDirect
• Cloud infrastructure with VXLAN overlay networks
• Storage fabrics with NVMe over Fabrics (NVMe-oF) support
• Financial trading networks requiring low latency and high throughput

6. Technical Specifications
