What did you buy?
Yes, I know - it's expensive. However, their support is fantastic and my employer agreed to pay for a portion of the licensing since I mostly require this for WFH. Zero issues, passive cooling, top notch security and this thing just freaking purrs.
Can you recommend quiet 10Gbps switches that support copper links?
To be frank, in the long run if you plan to make any changes to your setup, buying transceivers from FS.com and fiber cables (even armored fiber) for that matter is about the same price as copper direct attach cables. Also much easier to cable manage and they can be used with cable lengths from 0.2m to 400m in most cases.
I currently use a Cisco Nexus 3064 - https://www.ebay.com/p/219487215
It's kind of loud but I keep my hardware in a closet and to be honest, enterprise hardware like this makes heat and needs fans for a good reason haha.
If you're looking for a more consumer entry and don't care about L3 routing Ubiquiti actually makes one hell of a damn good sfp+ "switch" for the money -> https://www.ui.com/unifi-switching/unifi-switch-16-xg/ and again - cannot recommend FS.com enough for their service and quality products. Even if it was a little weird that their sales rep immediately added me on LinkedIn?
Sadly I don't have enough free space currently so I have to bet on fanless tech (but I do enjoy it).
I meant normal Cat6 Ethernet 10Gbase-T cables, yep. If not, I can indeed buy a fanless Mikrotik switch with SFP+ cages and just buy 8-10 adapters from SFP+ to 10Gbase-T, I suppose.
Bookmarking your link, definitely will look into that switch when I have the proper closet space for server tech.
Similarly for mikrotik.
I usually find that companies with "licensable" features on their hardware are the ones locking their SFPs to their switches/etc in an effort to enforce what is basically a port license (aka buy our $80 SFPs instead of the generic ones we are rebranding so we can make $ on your port usage vs just adding a $$$/port license fee).
