SOFTWARE DISAGGREGATION:

SN3420 switches are ONIE-based, enabling full OS flexibility for a variety of networking environments. Whether deployed in traditional enterprise networks or open cloud-native infrastructure, SN3420 offers robust compatibility with NVIDIA Onyx, SONiC, and Cumulus Linux. These options allow IT teams to choose the operating system best suited to their automation tools, performance expectations, and operational workflows.

The switch supports advanced monitoring and observability with features like What Just Happened (WJH), In-band Network Telemetry (INT), and NVIDIA NetQ, delivering granular real-time insights into traffic and fault behaviour. With ONIE preinstalled, operators can seamlessly deploy the switch with their preferred NOS. This makes SN3420 an ideal choice for DevOps-driven workflows, containerised data centres, and AI workloads requiring flexible and programmable network fabrics.
