Nice score on the used switch! I used a 10GbE Mikrotik up until recently until it started having hardware failures (my second one, a few years older is running perfectly, been very happy with it). I got exceptionally lucky finding a used 64 port 40/100Gbps enterprise switch on ebay for $1000CAD (same switch here normally goes for $3-4k CAD used). Most of my ceph cluster is limited to 10Gbps (onboard RJ45 for 4/5 nodes, and the PCI-E slot on each is taken by NVMe drives), but I feel I'm already outgrowing that speed, my few nodes already saturate 10Gbps - NVMe drives are fast! Now I just gotta wait for 100GbE NICs to come down in price, I'm not sure I'm ready to buy a used NIC yet (was nervous about the switch, first used piece of network gear for me), but the knock off Intels are like $350 minimum here for a 2 port.

The only “new” NIC in my setup is the one in the 10G thunderbolt dock for my Mac, everything else was used and has worked perfectly.

Good to know! Not sure why I am so often shy on getting used. I've done it when the deals are simply very good, but that's just been with referb harddrives (with a warranty) and this switch, which was just too good of a deal. I gotta get braver there.

The thing I like about used networking gear is if it starts failing, it's really noticeable; TCP/IP is checksummed up so many assets.

And if I have to go back to gig for a week or two, the horror!

But it's not permanent data corruption.
