About the NVIDIA Spectrum SN4000
The NVIDIA Spectrum SN4000 delivers sub-microsecond latency through cut-through and store-and-forward switching architecture, powered by the Spectrum-3 ASIC. This non-blocking 1U rack-mount switch (part number SN4000-4S) combines line-rate performance with advanced Layer 2 and Layer 3 capabilities including VLAN, MLAG, IPv4/IPv6 routing, BGP, OSPF, and VXLAN EVPN. NVIDIA engineered this platform for demanding enterprise fabrics where deterministic forwarding and ultra-low latency are non-negotiable. The switch supports RoCEv2 with PFC, ECN, and DCQCN congestion management, making it ideal for RDMA-heavy workloads in storage and compute clusters.
Network engineers and AI infrastructure teams deploy the Spectrum SN4000 in data center spine, core, and aggregation layers where scale and reliability matter most. The platform runs NVIDIA Cumulus Linux or Onyx, giving operators flexibility in OS choice while maintaining consistent operational models. Built-in telemetry via In-band Network Telemetry (INT), streaming analytics, and hardware flow monitoring enable real-time visibility into network behavior. Redundant hot-swappable power supplies, field-selectable cooling paths, and comprehensive management protocols—SNMP, OpenConfig, gNMI, NETCONF, and REST API—simplify integration into existing automation workflows. Support for Ansible, Puppet, Chef, and Python SDKs ensures rapid deployment in large-scale environments.
