About the NVIDIA Spectrum-2 SN3700 Ethernet Switch
The NVIDIA Spectrum-2 SN3700 is a 32-port 100GbE Ethernet switch based on the Spectrum-2 ASIC, delivering 6.4Tb/s of aggregate non-blocking switching bandwidth in a 1U form factor. It is a popular choice for enterprises seeking a cost-effective entry point into Spectrum-2 capabilities, combining full RDMA over Converged Ethernet (RoCEv2) support with a comprehensive layer 2/3 feature set and the flexibility of NVIDIA Cumulus Linux. The SN3700 supports breakout to 25GbE for server-side connectivity, allowing it to serve as a top-of-rack switch in environments with both 25GbE and 100GbE server populations.
The SN3700 supports the same Spectrum-2 feature set as the SN3800, including EVPN/VXLAN, BGP, OSPF, MLAG, and hardware-accelerated RoCEv2. Its smaller port count makes it ideal for smaller pod configurations, remote data center locations, or organizations with moderate scale-out requirements that do not yet justify 64-port platforms. The switch integrates seamlessly with NVIDIA NetQ for unified telemetry and health monitoring across mixed Spectrum-2 fabrics.
The SN3700 is frequently deployed alongside the SN3800 in tiered architectures where the SN3700 acts as a leaf/ToR switch and the SN3800 serves as the spine. Its 1U footprint, redundant power and cooling, and full Cumulus Linux support make it a versatile building block for enterprise network modernization projects targeting open networking and disaggregated infrastructure strategies.
Ideal for
- Top-of-rack (ToR) leaf switch for 25GbE/100GbE server connectivity in enterprise data centers
- Entry-level spine switch for smaller leaf-spine fabrics with moderate bandwidth requirements
- RoCEv2 RDMA switch in smaller-scale AI/ML training deployments
- Remote data center or edge data center core switching
- Co-location (colo) facility customer switch for high-density 100GbE connectivity
- Open networking deployment leveraging Cumulus Linux for network-as-code automation
