We clean up after ourselves.

The NVIDIA Mellanox SN3700C delivers ultimate deployment flexibility with 32 ports of 100 Gigabit Ethernet that transform into 128 ports of 25GbE when you need maximum density. This refurbished Spectrum-2 switch serves double duty as either a high-capacity spine switch or an ultra-dense leaf switch, adapting to your exact network requirements.

Powered by the advanced Spectrum-2 ASIC, the SN3700C provides 6.4 Tbps of non-blocking throughput with 4.76 billion packets per second processing capacity. Deploy as a traditional 32x100G spine for east-west traffic, or use breakout cables to create the industry's densest leaf switch with 128x25G ports for connecting massive server deployments in a single rack unit.

Perfect for organizations that need deployment flexibility as infrastructure evolves. Start with 100G spine connectivity, then repurpose the same hardware as a high-density 25G leaf when expanding server count. Each QSFP28 port flexibly supports 1G, 10G, 25G, 40G, 50G, or 100G speeds, providing maximum investment protection.

Key Benefits:

• 6.4 Tbps switching capacity for demanding workloads
• 32x100G or 128x25G port flexibility in one switch
• 4.76 Bpps forwarding rate handles heavy traffic
• Dual-purpose spine or leaf deployment
• Zero packet loss with 42 MB shared buffer
• Native RoCE support for storage acceleration
• Repurpose hardware as infrastructure grows
• What Just Happened telemetry for rapid troubleshooting

Ideal Use Cases:

• Spine switches in 100G leaf-spine architectures
• High-density 25G leaf with 128 server connections
• AI training clusters requiring flexible connectivity
• Data centers transitioning from 25G to 100G
• Hyperconverged infrastructure deployments
• Storage cluster connectivity with RoCE
• Database infrastructures requiring low latency
• Scale-out applications with changing requirements

Technical Specifications:

• 32x QSFP28 ports supporting 1/10/25/40/50/100GbE per port
• 6.4 Tbps total switching capacity

• Port breakout: up to 128x 10/25GbE with splitter cables
• Spectrum-2 ASIC with consistent low latency
• 42 MB shared packet buffer with predictive congestion control
• Layer 3 routing with BGP, OSPF, VXLAN, and segment routing
• RoCEv2 support for RDMA over Ethernet
• 512K shared forwarding entries (ACL, routes, MAC, ECMP)
• 10X better VXLAN scale vs. previous generation
• Hardware-accelerated telemetry with submicrosecond granularity
• Dual redundant hot-swappable AC power supplies
• Integrated x86 processor for management
• Standard 1RU depth: 16.9 inches wide x 22.4 inches deep
• Runs NVIDIA Onyx, Cumulus Linux, or ONIE

This refurbished unit has been professionally tested and certified to like-new condition. Includes dual redundant AC power supplies and supports both port-to-cooling (P2C) and cooling-to-port (C2P) airflow configurations for flexible data center thermal management. Rail kit included.

The SN3700C's unprecedented flexibility makes it ideal for organizations with evolving requirements. Use as a 100G spine today, then redeploy as a high-density 25G leaf tomorrow without replacing hardware. Breakout cables sold separately.

The What Just Happened telemetry provides real-time visibility into network behavior, dramatically reducing troubleshooting time by answering when, what, who, where, and why issues occur. Hardware-accelerated histograms track queue depths at sub-microsecond granularity for unprecedented operational insight.
