Can you point to another 1U box that has more than 16MB per-port buffer?

I cannot. It's just that this is not enough buffer for longer distances
with multiple well loaded ports.

As I keep saying, this is the best price/performance box I have seen. I
am not criticizing it, just pointing out that it may not be the solution
to all purposes.

+1 for the Arista boxes.
We are a pure Cisco shop and looked at them to start replacing some gear
where it made sense. We didn't buy them because they didn't do
Rapid-PVST+ at the time. Yeah I know that's a Cisco-centric thing, but
they were tentative on implementing it but the timeline just didn't meet
our needs.

Seriously knowledgeable technical/dev guys and I know for a fact that a
pile of them came from the old Cisco 4K team back when the 4K's were
walking circles around the 6K team in terms of innovation.
If it make sense they are willing to implement features and they did so
for us even though we were a demo.

We had a question way back when distance limitations with SFP+ CU/CR/DA
5 meter cables and they actually got us on the phone with folks at Intel
that normal people just don't have access to.

Even though we don't have any Arista kit, their initial efforts left an
excellent impression on us.

P.S. They will give you temp access to the site if you ask but I too
agree that it should be an open model.
