Asking because I'm looking for something suitable for a homelab (using Mellanox 40GbE cards) that's in the same room I tend to occupy during the day.
When I used very early Mellanox switches (years ago), they were only suitable only for datacenters. aka permanent super noisy jet engine mode
Their 1U 10Gb/s Infiniband switch is still the noisiest piece of equipment I ever made the mistake of buying! (!!!)
If you listen in this video of my homelab: https://www.youtube.com/watch?v=-b3t37SIyBs
I would say that more than half of the total 'volume' is attributed to the three Arista switches. They are quite a bit louder than the Ciscos, and of course much louder than the Ubiquiti.
I certainly would not have one of these next to me in a work area.
On the other hand, they are the cheapest way to get 40G! With DAC cables it can be really inexpensive.
I'm currently looking into the HP 5900AF-48XG-4QSFP+ (JC772A) switches, as they seem to be a good price/performance mix on Ebay. :)
My homelab is currently just a small setup with 4 boxes using 40GbE and a few others with 10GbE. Only one of them really needs the 40GbE though, the other's could be made 10GbE and not care. ;)
Random example of this switch:

Can't seem to find any info about noise levels though. :(
That's clearly not going to be workable. Damn.
It has 2 40G, and it is very quiet (I have one)
Depending on the 1u server, that's still super noisy. :(
