OVERVIEW

MSN3420-CB2FC / MSN3420-CB2RC Spectrum-2 25GbE 1U Open Ethernet Switch with Cumulus Linux, up to 48 ports, C2P/P2C Airflow

SN3420

As data-center switching architectures increasingly adopt 100GbE, the SN3420 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 in a compact 1U form factor. The SN3420 is an ideal ToR switch platform, delivering a total throughput of up to 2.4 Tb/s with a processing capacity of 3.58 Bpps. The SN3420 enables the seamless use of QSFP28 connections for leaf-spine topology and future-proofing the data center.
