The Mellanox Spectrum-2 MSN3700 is NVIDIA’s 32-port 200GbE spine switch designed for high-performance AI, cloud, and telecom data centers. Built on the Spectrum-2 ASIC, it delivers 6.4 Tbps switching capacity and processes over 8.33 billion packets per second—all within a 1U form factor. Its open networking architecture supports Cumulus Linux, SONiC, and native Linux, giving IT teams unmatched flexibility while avoiding vendor lock-in. Features like “What Just Happened” (WJH) telemetry and digital twin simulation via NVIDIA Air simplify troubleshooting and accelerate deployment. The MSN3700 integrates seamlessly with ConnectX SmartNICs, BlueField DPUs, and NetQ orchestration to power everything from AI training clusters to 5G RANs. For telecom-grade needs, the SN3750-SX variant adds PTP, SyncE, and secure boot. This switch isn’t just fast—it’s adaptable, secure, and future-ready, making it a strategic backbone choice for next-gen data infrastructure.
