About the NVIDIA Spectrum SN3800
NVIDIA Spectrum SN3800 delivers 12.8 Tbps switching capacity and 9.52 Bpps forwarding rate, enabling true line-rate performance across all 64 x 100GbE QSFP28 ports. Built on the NVIDIA Spectrum-2 ASIC, this 1U rack-mount switch provides the throughput density and deterministic latency required for hyperscale data centers, high-performance computing clusters, and AI infrastructure deployments. Network engineers and infrastructure teams rely on the SN3800-4S for its proven ability to handle east-west traffic at scale without compromise.
The SN3800 supports flexible port breakout—each QSFP28 port subdivides into 4 x 25GbE connections, yielding up to 256 logical 25GbE interfaces for heterogeneous workloads. Hardware-accelerated RoCEv2 with lossless fabric ensures near-zero packet loss for RDMA-intensive applications. Comprehensive protocol support—VXLAN, EVPN, BGP, OSPF, ECMP, and BFD—integrates seamlessly into modern automated networks. In-Band Network Telemetry (INT) and hardware timestamping deliver granular visibility. NVIDIA Cumulus Linux and Onyx operating systems unlock full programmability via Ansible, Terraform, NETCONF/YANG, and REST APIs, while redundant power supplies and hot-swappable fans ensure carrier-grade availability across 0°C to 40°C operating ranges.
Enterprise Deployment Scenarios
- Hyperscale cloud and data center spine/leaf fabrics requiring petabit-scale switching with minimal latency overhead
- AI and machine learning clusters demanding lossless RoCE connectivity for distributed training across GPU pools
- High-frequency trading and financial services networks where nanosecond-precision timestamping is critical
- Storage-area networks (SANs) consolidating block and object traffic over unified 100GbE infrastructure
- Research and academic supercomputing centers deploying tightly-coupled, low-latency interconnects
