About the NVIDIA Spectrum SN3800 - 400GbE (SN3800-1S)
The NVIDIA Spectrum SN3800-1S operates as a spine or leaf fabric switch supporting L2/L3 routing with BGP/OSPF control planes and VXLAN/EVPN overlay networking—architecture choices that determine whether this switch anchors your core or edge deployment. Built on the NVIDIA Spectrum-2 ASIC, the SN3800 delivers 12.8 Tbps switching capacity and 6.25 Bpps forwarding throughput in a compact 1U form factor, making it ideal for hyperscale data centers and high-performance computing clusters where density and power efficiency matter. Network engineers and infrastructure teams specify the SN3800-1S for mission-critical fabric roles because it combines extreme bandwidth with intelligent telemetry and flow control.
This NVIDIA switch features 32 native 400GbE QSFP-DD ports with flexible breakout support—run 4×100GbE, 2×200GbE, 4×25GbE, or 4×10GbE per port to match heterogeneous workloads. RoCEv2 support with Priority Flow Control ensures lossless transport for RDMA applications, while NVIDIA What Just Happened (WJH) telemetry and streaming analytics provide deep packet visibility for rapid troubleshooting. Built-in automation hooks—Ansible, Puppet, Chef, OpenConfig, NETCONF/YANG, and REST APIs—streamline zero-touch provisioning across large fabric deployments. Redundant hot-swappable power supplies and fan modules guarantee continuous operation without manual intervention. NVIDIA Onyx NOS simplifies management across spine-leaf, border leaf, and collapsed-core topologies. Contact Omnixon Global to request a detailed specification sheet and RFQ for the SN3800-1S.
