Brocade ICX Series (cheap & powerful 10gbE/40gbE switching)

Instead of one 7250-48P you can go with two 7150-24P. If you stay below a certain PoE budget (I do not have the number in my head) these can run fan less in the so called silent mode.

Depending how many SFP+ ports you need, the 7150s only have 4 otherwise I’d have one of them instead of my 7250

Have you tested to run 6 of them (2 in parallel x 3) ? Tempted to buy and test out. I currently have 2xJuniper ex3300 24p (almost dead silent with noctuas), I'm trying to replace them with a 7250 48P, but too much noise (I have 3x Mechantronics right now).

Yeah I have; at least without doing anything else I didn't notice any performance improvement by adding fans in series. I'm going to experiment with adding ducts and stators between them to see if that makes an impact but I can't recommend it at the moment.
