The Arista 7280 series has models with moderate amounts of high speed ports to go along with a larger number of lower speed ports, for example 7280CR3A-24D12 has 24x 100G and 12x 400G 7280CR3A-48D6 has 48x 100G and 6x 400G

*nods* Usually, I don't need lots of ports. Usually, just a few will do.
That's the annoying thing: they usually come with (and I'm exaggerating to avoid getting caught up in minutiae) two high-speed ports or 50, but rarely six, eight, or ten.

Is it paradoxical to wonder what low-cost full table (or close to it) 400G options there are? An earlier thread looks like the Arista 7280QR-C36 is "almost" there for 100G at a reasonable $3k, but a quick look at 400G-capable goes up, well, 4x in price, though one does get fully into DFZ capable devices then.
It seems like anything with more than low 6 digit route capability goes into full-scale multi-million capability, which is great technically, but not so great financially.
