I’ve been doing networking for 30 years. It still blows my mind. I build a 5-10 million dollar data center LAN. 5 years later it’s worthless and we fork lift upgrade the whole damn thing. Rinse repeat all over the data centers.

5 years. That’s about the best you can get out of network gear before a rip and replace the whole damn thing.

2000 - wow!  Gig Ethernet
2005 - wow!  Gig Ethernet copper
2007 - wow!  10 gig
2013 - wow!  High density line rate 10 gig, 40g is here
2017 - wow!  40g is cheap, 100gig is now the norm
2021 - wow!  A 100 gig wan link isn’t a big deal. I can do 32x100g ports at line rate.

The whole “cloud” thing was tried back in early 2000s as application service providers. With this kind of bandwidth it’s not a problem.

It’s to the point the network is so powerful the hosts can’t keep up.

You want a 100gig connnection to your host?  Sure!  But you can’t even push the 2x25

Ecmp. Don’t need it…yet.

100gig is the new 40.

i get like a gig down service but if i am too far from the router it's closer to 100.
I edit videos and stuff so transfer around some decent size files.
It's usually not even worth my time to move to the room with the router in it...

Ugh.  We are so behind up here.  Our core is still just 10g in a ladder from the bottom of alaska to the top. I just flew out to a village to provide a clinic 10 whole megs with 500mil rtt.  We need some of that infrastructure trillions bruh.

a couple months ago I upgraded two machines to 2.5gbps copper, got a 5 port 2.5gbps switch and 4 cat6a cables for about $200. This is just for transferring large files between machines, although the spinning disks can't quite keep up since I'm not running RAID. But SSD in one machine to SSD in the other I get almost 275MBps

I did some 10mbps networking back in the day with bnc cables, but I think most of the cards I used were ISA not PCI. By the time PCI cards were reasonably affordable it was the 3com 3c905 card that was ubiquitous. I worked at Disney Online in the late 90's and one of my jobs was buying 3c905's and cat5e patch cables by the case and swapping them out as we transitioned our internal network to 100mbps.

It's amazing how much transmission technology has changed over the years. Troubleshooting sure is much easier now, but I still get stuck working on legacy stuff every once in a while.

Most businesses aren't data centers.

We make that shit last.
I dont have one customer that's on 10gb hardware across the board.

Maybe a few server NICs plugged into one of the few 10gb backbone ports on the switch.

Where would you recommend looking for inexpensive used networking gear and compute/storage gear?

E.g. if one wanted to build a data center with last year's (so-to-speak) equipment?

I used to do "time share" on a teletype machine that transmitted at the amazing speed of 110 bits/second around 1970.

It used punched tape for uploading my Fortran programs.
