About the NVIDIA Spectrum SN1600 - 100GbE (SN1600-1S)
The NVIDIA Spectrum SN1600 delivers 4.8 Tbps of aggregate switching capacity with a forwarding rate of up to 3.57 Bpps, providing line-rate performance for demanding data center environments. Built on the NVIDIA Spectrum-1 ASIC, this 1U fixed form-factor switch combines ultra-high throughput with enterprise-grade reliability and operational flexibility.
The SN1600-1S features 48 × QSFP28 ports, each delivering 100GbE connectivity to support massive east-west traffic patterns in modern cloud and HPC deployments. NVIDIA Onyx, a Linux-based network operating system, powers intelligent automation through REST API, OpenConfig, gNMI, Ansible, and Puppet integrations. Layer 2 capabilities include VxLAN, VLAN, STP/RSTP/MSTP, LACP, and LLDP; Layer 3 routing supports BGP, OSPF, ECMP, static routing, PIM, and IGMP. RoCE support—both RoCEv1 and RoCEv2 with lossless Ethernet via PFC and ECN—ensures predictable, low-latency performance for storage and compute clusters. Shared packet buffering with per-port configuration, redundant hot-swap power supplies, and selectable front-to-back or back-to-front airflow accommodate diverse rack architectures. Management options include out-of-band RJ-45 and console connectivity, while streaming telemetry, sFlow, and SNMP enable real-time visibility. Operating from 0°C to 40°C, the switch integrates seamlessly into standardized data center infrastructure.
Typical Enterprise Deployments
- High-performance computing (HPC) clusters requiring low-latency, lossless fabric interconnects
- Hyperscale data center spine-and-leaf architectures with massive bandwidth aggregation
- Storage area networks (SANs) leveraging RoCE for hardware-accelerated RDMA traffic
- Multi-tenant cloud environments demanding consistent throughput and network isolation via VxLAN
- AI and machine learning training clusters with synchronized, time-sensitive communication patterns
Network engineers and infrastructure teams seeking deterministic, carrier-class 100GbE switching at scale should contact Omnixon Global to discuss availability, integration support, and RFQ for the NVIDIA Spectrum SN1600-1S.
