Mellanox NVIDIA SN3700 Spectrum-2 32×200GbE 1U High-performance Switch

NVIDIA Spectrum SN3700 is a powerful 1U 200GbE switch purpose-built for cloud-scale, AI-driven, and high-performance computing environments. Designed to meet modern data centre needs, it supports up to 32 ports of 200GbE and a total switching capacity of 6.4 Tbps. With ultra-low latency, deep telemetry, and support for open network operating systems, the SN3700 provides an efficient, scalable, and programmable network fabric.

KEY FEATURES:

• 32 × 200GbE QSFP56 ports (backwards compatible with 100G/50G/40G)
• 6.4 Tbps switching capacity, 8.33Bpps forwarding rate
• NVIDIA Spectrum-2 ASIC with ultra-low ~425ns latency
• Fully open platform with SONiC, NVIDIA Cumulus Linux, and Onyx support
• Precision Time Protocol (PTP), WJH, and GPUDirect RDMA integration
• Modular front-to-back or back-to-front airflow
• Dual hot-swappable AC power supplies
• 1U rackmount design ideal for spine/super-spine deployments

TECHNICAL SPECIFICATIONS:

SN3700 switches are ONIE (Open Network Install Environment)-based devices that support a variety of operating systems while utilising Open Ethernet and Spectrum-2 ASIC capabilities.
SN3700 operates in three modes:

• Includes NVIDIA Onyx, an enterprise-grade switching OS with standard CLIs and automation features.

• Integrated with Cumulus Linux, offering a Linux-native user experience on switch hardware.

• ONIE image is ready to install with the aforementioned or another ONIE-based OS.

SN3700 delivers high-speed interconnectivity across AI/HPC data centres as part of NVIDIA's complete end-to-end solution that includes BlueField DPUs, ConnectX NICs, and LinkX cables or transceivers. NVIDIA NetQ and telemetry tools enable efficient network deployment and visibility. This integrated solution accelerates design, increases control, and improves ROI.

SN3700 offers advanced hardware features including dynamic shared buffers, deterministic wire-speed forwarding, and programmable telemetry. It is powered by Spectrum-2 and a powerful x86 processor, unlocking greater flexibility for evolving network designs.
