Mellanox SN2410
The Mellanox SN2410 is a 25GbE/100GbE network switch manufactured by Mellanox (now NVIDIA). It has 48 25GbE ports, and 8 100GbE ports. This switch uses GRUB (by default) and has a relatively standard UEFI BIOS, meaning that it can easily run NixOS without much trouble.

Setup
In order to get NixOS working with this switch (and all of it's many ethernet ports), some manual configuration is needed. You can use a regular installer ISO to get NixOS on this machine, but for all ports to be functional, some extra configuration is needed. Add this to your system's configuration:
boot.kernelPatches = [
{
name = "mlx-stuff";
patch = null;
extraConfig = ''
MELLANOX_PLATFORM y
MLXREG_HOTPLUG m
MLXREG_IO m
MLXREG_LC m
NVSW_SN2201 m
SENSORS_MLXREG_FAN m
'';
}
];
boot.blacklistedKernelModules = [
"i2c_mux_reg"
];
This adds in some missing kernel drivers for the switch into your kernel, and blacklists the `i2c_mux_reg` driver (which interferes with the mlxsw_spectrum driver).
