One of many Linux kernel patch series that NVIDIA has been working on recently to upstream to the mainline Linux kernel are the adjustments needed for Linux running on their newest Smart Switch networking products for the data center.
The NVIDIA Smart Switch SN4280 is part of their SN4000 Open Ethernet Switch family focused on cloud, storage, and AI with speeds up to 400 GbE and typically deployed running NVIDIA Cumulus Linux, NVIDIA Onyx, or SONiC. With the patches they are working to upstream to the mainline Linux kernel it reduces NVIDIA's maintenance burden while also opening up new possibilities for other Linux platforms to be deployed on the NVIDIA Smart Switch SN4280.
Similarly, the tentative Linux patches also provide support for the new 2U switches the NVIDIA SN5610 and SN5640 as well as the SN2201 OCP rack.
The patch series describes this latest NVIDIA Smart Switch platform enablement work as:
Provide platform support for Nvidia (DPU) Data Processor Unit for the Smart Switch SN4280.
The Smart Switch equipped with:
- Nvidia COME module based on AMD EPYC™ Embedded 3451 CPU.
- Nvidia Spectrum-3 ASIC.
- Four DPUs, each equipped with Nvidia BF3 ARM based processor and with Lattice LFD2NX-40 FPGA device.
- 28xQSFP-DD external ports.
- Two power supplies.
- Four cooling drawers.
Drivers provides support for the platform management and monitoring of DPU components. It includes support for health events, resets and boot progress indications logic, implemented by FPGA device.

SN5640 is a 51.2Tbps switch based on Nvidia SPC-5 ASIC. It provides up-to 400Gbps full bidirectional bandwidth per port. The system supports 64 OSFP cages and fits into standard 2U racks.
SN5640 Features:
- 64 OSFP ports supporting 2.5Gbps - 400Gbps speeds.
- Air-cooled with 4 + 1 redundant fan units.
- 2 + 2 redundant 2000W PSUs.
- System management board based on AMD CPU with secure-boot support.
SN5610 is a 51.2Tbps switch based on Nvidia SPC-4 ASIC. It provides up-to 800Gbps full bidirectional bandwidth per port. The system supports 64 OSFP cages and fits into standard 2U racks.
SN5610 Features:
- 64 OSFP ports supporting 10Gbps - 800Gbps speeds.
- Air-cooled with 4 + 1 redundant fan units.
- 2 + 2 redundant 2000W PSUs.
- System management board based on AMD CPU with secure-boot support.
