SN2201 
Overview
The NVIDIA Spectrum SN2201 is a 1U open Ethernet switch featuring 48×1GbE RJ45 ports and 4×100GbE QSFP28 ports, delivering up to 448Gbps switching capacity. Designed to flexibly serve as a top-of-rack switch or an out-of-band management switch, the SN2201 supports non-blocking 100GbE uplinks with advanced ASIC-level telemetry and a 16MB fully shared buffer for efficient 1G switching. Compatible with multiple operating systems including Cumulus Linux and SONiC, it is ideal for modern data centers with 1G access requirements.
