About the NVIDIA Spectrum SN1500 - 25GbE (SN1500-1S)
L2/L3 switching capabilities—BGP, OSPF, VXLAN, and EVPN support—determine fabric role and deployment flexibility. The NVIDIA Spectrum SN1500-1S is a high-density, low-latency switch purpose-built for modern data center architectures where sub-microsecond cut-through latency and wire-speed forwarding are non-negotiable. Built on the NVIDIA Spectrum-1 ASIC and delivered in a compact 1U form factor, this switch combines 96 ports of 25GbE SFP28 connectivity with 2 uplink ports of 100GbE QSFP28, delivering 2.4 Tbps switching capacity and 1.786 Bpps forwarding rate. NVIDIA Onyx operating system enables advanced Layer 3 routing (BGP, OSPF, ECMP, static routing), overlay networking (VXLAN, EVPN), and RoCE support (RoCEv1, RoCEv2) for GPU-accelerated workloads and storage-intensive environments.
Network engineers and infrastructure architects will appreciate the robust management suite: CLI, REST API, OpenConfig/YANG, SNMP, and sFlow protocols, plus What Just Happened (WJH) real-time per-packet diagnostics for troubleshooting at scale. Redundant hot-swap power supplies and hot-swap fans with flexible airflow direction (front-to-back or back-to-front) ensure operational resilience in demanding 0°C to 45°C environments. Layer 2 features include VLAN, MSTP, LACP, LLDP, PFC, and ECN for priority-driven traffic handling. The SN1500-1S (part number SN1500-1S) is ideal for high-performance computing clusters, AI training fabrics, and hyper-scale storage deployments requiring deterministic latency and massive east-west bandwidth.
