- Powered by NVIDIA Spectrum-2 ASIC
- Offers port speeds spanning from 1GbE to 400GbE
The NVIDIA® Spectrum™ SN3000 series switches, based on the second generation of Spectrum switch ASIC, are purpose-built for leaf, spine, and super-spine data center applications. Allowing maximum flexibility, the SN3000 series provides port speeds spanning from 1 to 200Gb/s with 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.
As data center switching architectures increasingly adopt 100GbE, the SN3420 switch offers a high-performance, cost-effective way to evolve host connectivity from 10G to 25G. Equipped with 48 ports of 10/25GbE and 12 ports of up to 100GbE and utilizing 25G NRZ per lane in a compact 1U form factor, the SN3420 is an ideal top-of rack (ToR) switch platform, delivering a total throughput of up to 2.4Tb/s with a processing capacity of 3.58Bpps. The SN3420 enables the seamless use of QSFP28 connections for leaf-spine topology and future-proofing the data center.
