Description

NVIDIA Mellanox MSN3420-CB2F 1U Open Ethernet Switch: This is a 1U fixed-configuration Spectrum-2-based Ethernet switch with 48 × SFP28 ports for 25GbE access and 12 × QSFP28 ports for 100GbE uplinks (NVIDIA P/N 920-9N213-00F7-0X0). The CB2F suffix denotes the dual AC PSU configuration with P2C (Power-to-Connector, forward) airflow. This is a brand-new unit.

Engineering Context

The MSN3420-CB2F is built on the Mellanox Spectrum-2 ASIC. NVIDIA publishes a switching capacity of 2.4 Tb/s for the SN3420 with a processing capacity of 3.58 Bpps (48 × 25GbE plus 12 × 100GbE = 2,400 Gb/s). Each QSFP28 uplink can be configured as 4 × 25GbE breakout for additional access capacity. The switch supports ONIE for installation of Mellanox Onyx, Cumulus Linux, or SONiC, and provides hardware acceleration for VXLAN, RoCEv2, and telemetry. P2C airflow uses the standard hot-aisle/cold-aisle data center orientation.

Deployment & Use Cases

Top-of-Rack 25GbE access for ConnectX-4 Lx / ConnectX-5 / ConnectX-6 server adapters with 100GbE leaf-spine uplinks. AI/ML cluster fabrics combining GPU compute nodes (25G NICs) with high-bandwidth NVMe-oF storage tier. Cloud and multi-tenant data centers requiring per-tenant VXLAN segmentation. Financial trading and CDN edge environments needing low-latency 25G access.
