If servers take up so much space, then does the warehouse they’re in just have to be Big Enough or can you wire servers together over multiple floors with long enough cables? Does this impact processing time? With huge server systems like Google, do they even HAVE an access point or a central node or is it just one, MASSIVE conglomeration of processing power?? Are there different types of cable for different purposes of what the servers are doing?? Im going insane. Madam I’ve been struck with The Ailment (ADHD)
OK! This one is really interesting because it's the reason why I don't believe that the Circus is abandoned. I mean that in the way that if TADC is following any kind of realistic standards, then the physical hardware behind the circus can't be just tucked away in an abandoned building somewhere. The demands for power and cooling are high. Even if we assume that automated systems take care of that, hardware WILL fail over years of operation.
(Sorry this took so long) Once again, long post under cut
Have you ever seen Google go down? Maybe Youtube? In the past when they were a small website, sure, but not anymore. If you can make a connection, then you will be able to reach those servers. I assume that the circus has a similar setup, as No matter what, there is a digital space for the humans to occupy. That means that there is ZERO downtime.
But these devises live in the real world, connected to the very real power grid. How can they be powered 24/7? A bad storm hits the area and a tree takes out the power lines, do all of the websites hosted on those servers have to wait the hours, possibly days for that line to be fixed? Nope! These centers advertise 24/7 service and they mean it. What this means is that typically, they will have ON SITE generators that can run the ENTIRE center at a moments notice. Some even have an extra generator on standby in case one of the generators malfunction. Redundancy is the name of the game. If something is essential to function, then there WILL be an exact copy on site as a backup. That is why these big websites never go down for service, there is ALWAYS something available to connect to.
But what most people don't realize is the water requirements. Have you ever seen the statistic that chatGPT consumes like 2-3 THOUSAND liters of water every day? And thought, why the fuck does a computer need water? Isn’t water a bad thing for computers? But water has a very useful ability in the way that it handles heat. It’s the same way how your sweat evaporating cools you off. Think of cooling as just removing the heat instead of actually making cold. So water is used in the cooling of these data centers, which is to say, water is used as the refrigerant. It’s a similar concept to how your fridge works, except the refrigerant is lost over time. The water is allowed to evaporate and leave the building because it makes for more efficient cooling. Here’s a video that goes more into detail about water loss cooling for data centers specifically.
As for the actual building, data centers with multiple floors do exist! The reason one may be a single story has more to do with the cost of land vs the cost to build a building with multiple floors that can support the weight of all of those machines. If land cost more than the steel and concrete needed for multiple floors, then. yes, the shorter the cable the more efficient the data transfer, but the time loss is so short that it’s pretty much unnoticeable to the human eye. Some places also standardize their wire lengths, so every server gets the same load time regardless of the actual placement of the server.
But the people who care about that are insane stock traders (not gamers believe it or not) and advancements have made it so that time delay only starts to matter when a cable reaches miles long in length. And those advancements are Fiber Optics! Fiber being literal fibers (either glass or plastic) and Optics as in lenses or reflection. This is because fiber optic cables carry light instead of electricity. Because light is fast as fuck. So then where does the delay come from? Turns out even with the most reflective, chemically perfect fibers, light scatters and eventually data is lost. So repeaters are put in to repeat the input signal, refreshing it. But these repeaters aren’t perfect, so lag is eventually introduced, so modern fiber optics use amplifiers. Amplifiers strengthen the original signal instead of repeating it, making for faster transfers of days.
But you want to know about how these things are wired in terms of electricity! How these things can fit so much electricity in one building? The answer is industrial grade wiring! It's different from the power cables that you find in your house. Well, the wires themselves may be the same, the difference comes in at the fuse box. Here’s a lady plugging all of the wires in a house into the fuse box. The box itself is then plugged into the power line, which provides the electricity. Multiple lines or higher gauge lines will be ran from the power plant to the data center. The exact set up depends on where the data center is in relation to the power plant, who’s building it, and state laws.
Also, for industrial wiring, they usually run the wires through metal pipes instead of letting the wires sit against the insulation. Here’s a guy who wired his house like this. He doesn’t go into detail about what everything means but you don’t need to know all of that to appreciate the pipe work. If you want me to go into electricity as a form of power and the different phases of AC... I'm going to be honest just call me on discord so I can get out the whiteboard. I will give you a whole college grade lecture about how electricity works.
Servers don't have a central node, their operation and purpose is different from computer clusters. While each unit is wired together in a cabinet, each unit operates as it's own individual machine. So, a computer cluster will be spreading one load over multiple machines, a server takes many small loads (<- terrible oversimplification but it works). Everything around it exists to route the right requests to it, power it, cool it, and monitor its operation. But they do have access points! As in, you can connect to it directly or use SSH shell to remotely connect to it. SSH shell is just a secure way to connect to the server, as a maintenance level of access is usually not something that you want anyone to be able to pick up on.
Last but not least, YES! There are many different kinds of cables made for different tasks! Or just to be cheap. The more you get into engineering the more you realize half the shit that we do is because it's the cheapest option that still meets requirements! I left some interesting videos in the bottom of this if you are really curious, but I honestly think that figuring out the exact wires is getting a little too into the weeds for this.
So, to summarize, data centers need generators, water for cooling, and have spare copies of pretty much everything. That’s why it’s so god damn rare to see big websites like google docs down but Ao3 goes down every now and then. He's a bunch of helpful videos that I uses when writing this.

SWITCH BOXES. you said that’s what monitors the connections between systems in the computer cluster, right? I assume it has software of its own but we don’t need to get into that, anyway, I am so curious about this— in really really large buildings full of servers, (like multiplayer game hosting servers, Google basically) how big would that switch box have to be? Do they even need one? Would taking out the switch box on a large system like that just completely crash it all?? While I’m on that note, when it’s really large professional server systems like that, how do THEY connect everything to power sources? Do they string it all together like fairy lights with one big cable, or??? …..the voices……..THE VOICES GRR
I’m acending (autism)
ALRIGHT! I'm starting with this one because the first question that should be answered is what the hell is a server rack?
Once again, long post under cut.
So! The first thing I should get out of the way is what is the difference between a computer and a server. Which, is like asking the difference between a gaming console and a computer. Or better yet, the difference between a gaming computer and a regular everyday PC. Which is... that they are pretty much the same thing! But if you game on a gaming computer, you'll get much better performance than on a standard PC. This is (mostly) because a gaming computer has a whole separate processor dedicated to processing graphics (GPU). A server is different from a PC in the same way, it's just a computer that is specifically built to handle the loads of running an online service. That's why you can run a server off a random PC in your closet, the core components are the same! (So good news about your other question. Short answer, yes! It would be possible to connect the hodgepodge of computers to the sexy server racks upstairs, but I'll get more into that in the next long post)
But if you want to cater to hundreds or thousands of customers, you need the professional stuff. So let's break down what's (most commonly) in a rack setup, starting with the individual units (sometimes referred to just as 'U').
Short version of someone setting one up!
18 fucking hard drives. 2 CPUs. How many sticks of ram???
Holy shit, that's a lot. Now depending on your priorities, the next question is, can we play video games on it? Not directly! This thing doesn't have a GPU so using it to render a video game works, but you won't have sparkly graphics with high frame rate. I'll put some video links at the bottom that goes more into the anatomy of the individual units themselves.
I pulled this screenshot from this video rewiring a server rack! As you can see, there are two switch boxes in this server rack! Each rack gets their own switch box to manage which unit in the rack gets what. So it's not like everything is connected to one massive switch box. You can add more capacity by making it bigger or you can just add another one! And if you take it out then shit is fucked. Communication has been broken, 404 website not found (<- not actually sure if this error will show).
So how do servers talk to one another? Again, I'll get more into that in my next essay response to your questions. But basically, they can talk over the internet the same way that your machine does (each server has their own address known as an IP and routers shoot you at one).
POWER SUPPLY FOR A SERVER RACK (finally back to shit I've learned in class) YOU ARE ASKING IF THEY ARE WIRED TOGETHER IN SERIES OR PARALLEL! The answer is parallel. Look back up at the image above, I've called out the power cables. In fact, watch the video of that guy wiring that rack back together very fast. Everything on the right is power. How are they able to plug everything together like that? Oh god I know too much about this topic do not talk to me about transformers (<- both the electrical type and the giant robots). BASICALLY, in a data center (place with WAY to many servers) the building is literally built with that kind of draw in mind (oh god the power demands of computing, I will write a long essay about that in your other question). Worrying about popping a fuse is only really a thing when plugging in a server into a plug in your house.
