I hope this isn't a dumb question: Do the Ethernet switches you're

No modern switch chip has a crossbar. They're rings, and the ring has
high enough capacity to work as well as a crossbar would.
I don't think this is true anymore. I've been looking into this myself
recently, and from what I've been told, some high-end Ethernet switches
do have crossbar chips inside them. Unfortunately, I haven't been able
to identify any models that do, but I'm also not a network engineer, so
I'm not up with the features of all the different models.
Of course if they're only in the "high-end" or "high-performance"
Ethernet switches, they probably cost as much or more than an IB switch.
