  • Thing is though, most consumer networking gear is capable of a maximum of 1gbit, so to even take advantage of 2gig or 2.5gig you at least need a router with a 2.5gig uplink. If you have this you can have a couple of people on the network using a gig each.

    My setup is a 1.2g cable connection going into a 2.5g port on my router, with a couple of servers connected to the router over 10g. This basically lets me download off of my servers at the full speed of the network but the rest of my devices are limited to 1gig.

    Going up to 20gig would require a large investment to see the benefits. First you would need a router with a 25g uplink port, which is really only going to be found on a specific tier of “enterprise” gear. These routers aren’t going to have a bunch of ports so you are going to need to dump the output either to a 25g switch or a couple of 10g switches (probably the most cost-effective option). From there you can distribute out to 20 machines at 1g.

    Anyway, you are definitely right about the aim of a service like this but to see the benefits of a 20g connection would require some very expensive and specialized equipment.




  • Doubtful that this is using traditional per-device water cooling. I’m betting that this is traditional hot row/cold row cooling and there is an evaporative component of the HVAC coolant loop to reduce the power requirements of the system as a whole.

    Lemmy loves to shit on MS but they are constantly innovating in efficient data centers because spending less to operate directly reduces their expenditures, which directly equals profit on a service with fixed costs and multi-year reservations like Azure.

    You can bet that if the solution was as simple as what you suggest that they would have been doing it for years, but the thermal considerations for one machine and the thermal considerations for 100,000 machines are not the same. The #1 priority to operate that many systems is to use as little power as possible because power is not only the biggest expense but also the primary limiting factor on the total number of systems you can host.
