About the NVIDIA Spectrum SN3800
The NVIDIA Spectrum SN3800 from NVIDIA is enterprise-grade Network Switches hardware built for data centers. It features 25GbE interface, 400GbE speed. The NVIDIA Spectrum SN3800 is a high-density, 100GbE/400GbE-capable spine and core switch built on NVIDIA's Spectrum-2 ASIC architecture. Delivering 12.8 Tbps of non-blocking switching capacity across 64 ports of native 100GbE (QSFP28), the SN3800 is engineered for large-scale data center fabrics that require deterministic low latency, deep packet buffering, and advanced telemetry. The Spectrum-2 ASIC provides hardware-based RoCE (RDMA over Converged Ethernet) acceleration, e Available in brand new condition. NVIDIA network switches products are trusted by enterprises and data centers worldwide. Available from Omnixon Global. Contact our sales team to request a quote.
