  • 20 Gig is nowhere near what most current cloud data centers are using. Most existing infra have at least at 100Gbps NICs. State of the art right now is 800Gbps. Your 20Gbps enterprise server might be enough for bare-metal AD, but if you include us-tail latency network storage and all the other fancy stuff you’ll need way more than that. Doubly more so for HPC, ML and other data heavy workloads. Existing links can already see multi-terabit of aggregate throughput, it wouldn’t be surprising if someone decided to have a bunch of HD cameras, streaming, torrenting, etc at their house generating traffic 24/7 because someone thought it was a fun thing to do.

    For the gateway switch power draw, I can think of an off-the-shelf software switching solution at 75w, and that’s for 100Gbps. A 20Gbps ASIC switch would be a lot less power hungry than that. If you’re willing to go experimental, here’s a theoretical 400Gbps SmartNIC design that runs at 7w, all you need to do is write a basic L3 switching program with NAT and it should all work.




  • You can do it through democracies. Taiwan has two sets of high speed rail systems.

    Are they expensive to maintain? Absolutely. In fact they bankrupted 2+ companies until the government decided to step in and foot part of the bill. But then again, if the government isn’t willing to pay for basic infrastructure, what are taxes for?

    (Also as a tangent, the Taiwan high speed rail bentos are to die for. I had it 5+ years back and I still remember it. Super cheap meal in a disposable bamboo lunch box. Usually there are 1-2 choices per day. I had chicken thighs, pickled veggies, steamed pumpkin, and half a marinated tea egg. The bottom half of the lunch box was filled with rice. 10/10 would eat at a busy train station during rush hour again)
