Actually, its Intel ALTA silicon, connected via PCIe to the x86 server
underneath.

Pluribus also attach a Marvel Advanced NPU to the box, giving you extensive
extra network capabilities before you even need to get into the x86 CPU.

Switching packets is one thing. Trident is another and in high density,
high flow environments, it doesn't work too well. (head of line blocking
:-) )

We have a number of Pluribus switches deployed throughout our network.
