About the NVIDIA Spectrum SN3500
The NVIDIA Spectrum SN3500 (part number SN3500-4S) delivers cut-through forwarding architecture with a total switching capacity of 6.4 Tbps and a forwarding rate of up to 4.76 Bpps, enabling ultra-low-latency packet processing essential for high-performance data center environments. Built on the NVIDIA Spectrum-2 ASIC, this 1U rack-mount switch combines dense 200GbE connectivity with flexible port breakout capabilities, making it the preferred choice for network architects and infrastructure teams deploying converged AI, storage, and HPC workloads.
The SN3500-4S features 32 x 200GbE QSFP56 ports with support for 100GbE, 50GbE, 40GbE, 25GbE, and 10GbE breakout configurations via QSFP56 breakout cables. Management is handled via 1 x 1GbE out-of-band RJ45 and 1 x USB Type-A, with support for NVIDIA Cumulus Linux and NVIDIA Onyx operating systems. The switch supports comprehensive Layer 3 protocols—BGP, OSPF, IS-IS, ECMP, PIM, and IGMP—alongside overlay networking via EVPN and VXLAN, plus hardware-based RoCE v1 and v2 with lossless Ethernet features (PFC, ECN, DCQCN). Advanced telemetry via sFlow, SNMP, streaming gRPC, and in-band network telemetry provides real-time visibility, while automation frameworks including Ansible, Puppet, REST API, and Zero Touch Provisioning (ZTP) accelerate deployment. Redundant hot-swappable AC power supplies and selectable airflow options (PSE/PSI) support flexible datacenter layouts. Operating range extends from 0°C to 45°C, with support for up to 64K ECMP next-hop entries for massive-scale routing tables.
Deployment Scenarios
- High-performance computing (HPC) and GPU cluster interconnects requiring sub-microsecond latency and lossless transport
- AI and machine learning training environments demanding ultra-dense, high-bandwidth east-west fabric connectivity
- Enterprise storage networks leveraging VXLAN and EVPN for multi-tenant overlay isolation
- Cloud infrastructure and data center spine/leaf architectures at hyperscale
- Financial services and algorithmic trading networks requiring deterministic, ultra-low-latency packet forwarding
