I really, really would love to see someone make Sparx-5 switch. It's weird that I can't even find any commercially available/closed source switches with them (anyone know of any?).


Yep, really strange indeed.

I posted the link for the ServeTheHome article last year back in 2024 although it's really year 2023 article [1].

Layer 3 switch for examples from Cisco or Juniper used to cost more than USD100K only ten years ago but now they can be dirt cheap with advent of the networking switch SoC like SparX-5.

High end SparX-5-200 (VSC7558) supports up to 200 Gbps of switch core bandwidth, with flexible interface options including 1/2.5/5/10/25 GbE, and the unit cost is only USD165 [2].

Imagine having this kind of really affordable powerful enterprise layer 3 switch with Linux Foundation SONiC or DENT OS [4], [5].

Someone just need to crowd source this SparX-5 SoC based layer 3 switch and will be selling like hot cakes.

But I have not been able to find a place to buy one.
