Comment on Google Fiber goes big with 20-gig plan

I wouldn’t want to calculate what it’d cost to replace all my switches with 25G capable ones… then all the network cards… You’d have to have a really specific application to justify it.

Just cost me 1K to replace 3 NICs, 1 router, and 2 switches to freaking 2.5Gb.

  I got one of the 2.5 x 8 + 10 switches StH reviewed for like $80, and x520 nics are $20. I’m happy with it for homelab stuff!

  10Gbps used enterprise equipment is pretty cheap on eBay. Biggest problem I’ve had is getting compatible SFP+ adapters for the NICs.

    Flexoptix reprogrammable tranceivers are a godsend for that. We use them almost exclusively at work and so do quite a few of ours customers (Universities and other places of higher educaton). But it’s probably hard to justify the cost of a reprogrammer box for a household. You can buy their transceivers pre-programmed though.

You won’t but I will

Switch: mikrotik CRS504-4XQ-IN ($799.99) Cabling: QSFP28 to 4 x 25G SFP28 DAC ($63.00 per cable) NICs: Intel XXV710 25GB ($349.0)

I don’t know how many machines you have so for two machine it’s cost you $1562.97 and maxing out the switch would cost you $6651.83 but do you really have sixteen machines that need or can even physically saturate a 25GB line?

I think it’s more reasonable to get something similar to ubiquiti’s USW-Pro-Aggregation and have three machines capable of the full speed and 28 machines capable of half rate speeds (at a much lower cost per machine)

  What about a router?

    Both switches mentioned are L3 switches meaning they are a routers too.

    I have no idea how well a L3 switch would work on a residential WAN connection. But don’t L3 switches lack features like NAT, DHCP, DNS, Firewall, port forwarding, etc?
    
    DHCP and DNS (and Firewall, but I guess you don’t have a 25 Gbit/s FW) are of course easily moved elsewhere, but what about the others?

That’s the early adopter tax. Same as it ever was.

Buy a media converter and do 25G -> 40G and run a 40GbE home net. Retired 40Gb gear is ludicrously cheap.
