Mellanox Spectrum-2 MSN3420-CB2FC - Switch - L3 - managed - 48 x 25 Gigabit SFP28 12 x 100 Gigabit QSFP28 - back to front airflow - rack-mountable

As datacenter 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 Top-of-Rack (ToR) switch platform, delivering a total throughput of up to 4.8Tb/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.
