NVIDIA Spectrum MSN4700-WS2F 400GbE Open Ethernet Switch

1. MSN4700-WS2F Product Overview

The NVIDIA Spectrum MSN4700-WS2F is a high-performance 1U Open Ethernet switch designed for modern data centers requiring extreme bandwidth and flexibility. Part of the SN4000 series, this network switch delivers 32 ports of 400GbE connectivity, powered by the Spectrum-3 ASIC, ensuring low latency, high throughput, and advanced programmability for cloud, AI, and storage workloads.

2. Key Features

• 32 x 400GbE QSFP-DD ports supporting 1G to 400G speeds
• 12.8 Tb/s bidirectional switching capacity
• 8.4 Bpps packet processing performance
• 64MB fully shared packet buffer
• Pre-installed NVIDIA Onyx® OS with classic CLI
• Hot-swappable power supplies and fans
• Support for Open Networking and disaggregated software

3. Core Technologies

The SN 2000 series successor, MSN4700-WS2F leverages NVIDIA Spectrum-3 ASIC with support for:

• VXLAN routing and bridging
• RoCE (RDMA over Converged Ethernet)
• In-band network telemetry (INT) and streaming telemetry
• Programmable pipeline with deep packet inspection (512B)
• Open Ethernet standards including ONIE and SONiC

4. How It Works

The switch uses a cut-through forwarding architecture to minimize latency. The Spectrum-3 ASIC processes packets in a single pass, enabling line-rate performance even with advanced features like VXLAN routing, NAT, and ACLs. The fully shared buffer ensures fair bandwidth distribution and prevents congestion.

5. Applications

• Data center leaf/spine architectures
• AI and machine learning clusters
• High-performance computing (HPC)
• Cloud and hyperconverged infrastructure
• Financial trading and media networks
