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. |

I remember back in the 90s when a classmate said it was ridiculous to need 768 MB RAM. Even at that time I was like "bro, do you history?"

Guy working at the Apple Store- You will never fill up a 1000Mb drive.

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.

Strange, I was just looking up pictures of the 3Com 3c509 reminiscing about the good ol' days..

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

Thinnet Thicknet Arcnet TCNS DEC Asynchronous terminal DDS T1 T3 ISDN BRI and S/T 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. |

Quoted: Yeah, but the chassis the hosts are in sure can. And half of those connectors are dedicated to storage any way. View Quote View All Quotes View All Quotes Quoted: Quoted: 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 Yeah, but the chassis the hosts are in sure can. And half of those connectors are dedicated to storage any way. I’ve been screaming at nutanix for 40g nics. The host is slow as fuck. I don’t care if if it’s a hundred of them. |

I remember 1998, when dildos from the cable companies knocked on our door 5 times a week.
"Would you be interested in cable?" "Can I connect my computer to it?" "No." [slams door] |

I know the feeling….I still have night sweats over FDDI and Token Ring broadcast storms.

The change inherent in technology is what makes it so hard to do. And why it pays.

Quoted: Good career field ? View Quote Fuck no…. Seriously, it can be but understand you will need to specialize, keep up to date with training/certain and always watch out for outsourcing attempts. IT was once a great field, now it’s mostly shit. Infosec is where it’s at, that and ‘cloud’ but it’s not for everyone |

I hear you. Working in infrastructure is always entertaining. I always made the old gear available to the engineers to take home and put in their labs. Everyone benefits!

So, I should burn down my house wired with Cat 5e and walk away?

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. |

@spidey07 (or anyone for that matter),
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 just had to quote out 24 x 100G internet circuits for a customer.

![]() 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. |
