Description

NVIDIA MSN3420-CB2F Spectrum-2 Based 25GbE/100GbE 1U Open Ethernet Switch with Onyx 48 SFP28 Ports and 12 QSFP28 Ports 2 Power Supplies (AC) x86 CPU Short Depth P2C Airflow Rail Kit


SN3420 Series Switches

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 Top-of-Rack (ToR) network switch, 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.
