The NVIDIA Spectrum SN3000 series switches are based on the 2nd generation of Spectrum switches, purpose-built for leaf/spine/super-spine data center applications. Allowing maximum flexibility, the SN3000 series provides port speeds spanning from 1GbE to 400GbE, and a port density that enables full rack connectivity to any server at any speed. In addition, the uplink ports allow a variety of blocking ratios to suit any application requirement.
