- 512K on-chip flow counters
1U Open Ethernet Switch Bare Metal with ONIE 48 SFP28 Ports and 12 QSFP28 Ports
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.
