Product Description
NVIDIA Spectrum SN3000 Series Switch - MSN3700-VS2F
MSN3700-VS2F Product Overview
The NVIDIA Spectrum SN3000 Series, specifically the MSN3700-VS2F model, represents a significant leap in data center switching technology. Built on the powerful Spectrum-2 ASIC, this 1U open Ethernet network switch delivers exceptional performance, scalability, and telemetry capabilities. It is engineered for modern leaf, spine, and super-spine deployments, offering 32 ports of up to 200GbE connectivity. The SN 2000 series foundation ensures robust support for high-speed networking, cloud infrastructure, and hyperconverged environments, making it an ideal solution for enterprises seeking flexibility and future-proofing.
Key Features
- 32 QSFP56 ports supporting speeds from 10GbE to 200GbE per port
- 6.4 Tb/s bidirectional switching capacity with 8.33 Bpps processing
- Cut-through latency as low as 425 nanoseconds
- 42MB fully shared packet buffer for congestion management
- Comprehensive support for NVIDIA Onyx, Cumulus Linux, or ONIE-based OS options
- Advanced telemetry with NVIDIA What Just Happened (WJH) technology
- Hardware-accelerated RoCE for NVMe over Fabrics and AI workloads
Core Technology
The SN 2000 series leverages NVIDIA's Spectrum-2 ASIC, which incorporates a fully programmable pipeline and deep packet inspection capabilities. It supports advanced networking protocols including VXLAN routing, IPv6 segment routing, and network address translation (NAT). The architecture enables single-pass processing for both traditional and overlay networks, ensuring consistent performance without compromising feature richness. This network switch also integrates open Ethernet principles, allowing disaggregation of hardware and software to prevent vendor lock-in.
MSN3700-VS2F How It Works
The MSN3700-VS2F operates as a high-performance switching platform utilizing a shared-memory architecture. Incoming traffic is processed through the Spectrum-2 chip, which performs wire-speed forwarding, filtering, and telemetry collection. The switch supports cut-through forwarding mode, minimizing latency by beginning packet transmission before the entire packet is received. Built-in flow counters and hardware-accelerated telemetry provide real-time visibility into network performance, while the programmable pipeline allows custom packet parsing and editing up to 512 bytes deep.
Applications
This network switch is ideal for:
- Cloud data center leaf-spine architectures
- High-performance computing clusters
- AI and machine learning infrastructure
- Hyperconverged storage networks
- Financial trading environments
- Media and entertainment content distribution
- Enterprise campus core networking
The SN 2000 series design supports seamless integration with NVIDIA's end-to-end networking ecosystem, including ConnectX NICs and LinkX cables.
