QUESTION TWO:
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.
