About the NVIDIA Spectrum SN3100 - 25/100GbE (SN3100-1S)
The NVIDIA Spectrum SN3100 delivers sub-microsecond cut-through forwarding latency, eliminating store-and-forward delays that constrain traditional switching architectures. Built on the NVIDIA Spectrum-1 ASIC, the SN3100-1S combines a compact 1U form factor with enterprise-grade throughput: 6.4 Tbps switching capacity and 4.76 Bpps forwarding rate. This switch is engineered for network architects and infrastructure teams deploying high-performance, low-latency data center fabrics where microsecond differences impact application performance.
The SN3100-1S ships with 32 × 100GbE QSFP28 ports and supports breakout to 128 × 25GbE via 4x25G breakout cables, providing flexibility across multi-speed deployments. Redundant hot-swappable power supplies and hot-swappable fan modules ensure operational continuity, while dual airflow options—port-side exhaust (PSE) and port-side intake (PSI)—simplify integration into existing thermal designs. NVIDIA's software ecosystem spans NVIDIA Onyx (MLNX-OS) and NVIDIA Cumulus Linux, unlocking advanced routing (BGP, BGP Unnumbered, OSPF, ECMP), lossless Ethernet via PFC and ECN, and RoCE v1/v2 support. The 128K MAC table and on-chip shared packet buffer handle enterprise workload density, while VXLAN and EVPN overlays enable multi-tenant cloud and containerized environments.
Enterprise Deployment Scenarios
- High-performance computing (HPC) clusters requiring sub-microsecond latency and RDMA acceleration via RoCE
- Cloud data center spine-and-leaf architectures leveraging ECMP load balancing and VXLAN segmentation
- Storage area networks (SANs) demanding lossless Ethernet and priority flow control (PFC) for mission-critical I/O
- Multi-tenant service provider fabrics using EVPN for dynamic, scalable overlay networks
- AI/ML infrastructure requiring predictable, ultra-low-latency interconnect between compute nodes and GPU clusters
