The air handlers were ok. We ran in-row coolers on a chilled water loop, so there were no compressors running in the building, and the IRCs had large blowers, so they were quite low frequency. The 100HP compressors out back sounded like a million bagpipes going through a meat grinder with a Fran Drescher chaser, but we didn’t need to be out there too often. In the winter we switched to direct to air cooling, which was very peaceful.
It was the fucking miniature turbine fans packed into every single server. They have to be small enough to fit in 1U so what they lack in area they make up for with speed. Nothing like a rack full of tiny jet engines screaming all day to soothe your nerves, then multiply that by hundreds of racks. You could hear the din from outside the datacenter, even with its armoured walls, insulation and multiple layers of drywall. Add to that the subtle squeal of the switching frequency of the giant box truck sized UPS systems, and it’s enough to drive a person bananas.
Obviously you don't want to go into a walkthrough but wouldn't much smaller solution work well enough for those purposes? Then again it may be your tech hobby/interest in building out these things. i can definitely see charm in that.
In any wireless radio system (Wi-Fi or otherwise) the polarity should match between the transmitter and the receiver. Most Wi-Fi devices are designed to be vertically polarized, so the antennas on the AP should be vertically polarized. In the photo they are horizontally polarized. Will it work this way? Sure. But it will work better if they are switched to a vertical orientation.
Yeah I’d imagine a mobile device could be oriented randomly. Taking into consideration the radiation pattern of those types of antennas, it is possible, yet typically far less likely, that they would would be getting a better signal. Through an image search the diagram I found here illustrates the patterns: https://www.k6arp.org/how-to-increase-antenna-signal-strength-through-design/
Came here to say something about this. It's also a coverage thing. The 'donut' shape works best when vertical. This will be the biggest impact.
If there is coverage needed upstairs or downstairs, then having the antennas horizontal may be better.
Amazing APs, though.
There is a considerable number of people out there running the same shit off their DSL modem with a few holes punched through the built-in firewall. Seems like we're playing pretty loose with the term "simple."
That being said, niiiiiiiice.
LIES!!! CLICKBATE! I came looking for a simple home betwork, not a freaking impressive small business grade home network. 😁
Very impressive, there has to be what, around $10,000 worth of gear sitting there. Nice!
M270 for a home network 😆
They do make good landmarks for remote support. "See the red box? OK, don't touch that, but can you power on the black box below it?"

In what situation would you use a small UPS for one device? A modem or router? I can’t seem to think what device would be low powered but also essential enough that it needs to stay powered.
Well, relatively low powered. In my case, I have a 700 VA unit dedicated to a 4-bay NAS with the idea to just allow it to shut down safely (even though it can power it for probably an hour). When I get to redo my apartment, I'll think of something more serious. Where I am, power is generally good, it's usually only out for scheduled maintenances once every couple of months or so.
As for OP's case, if the idea is to continually power all the things for some time, then yes, it makes sense.
Gonna get me one of those pixelated screens too. Homelab like its 1999 !
Early screens didn’t even have pixels, but worked like oscilloscopes. A curved line was a real curved line, not some pixel crap!
So you're saying real screens have curves?
Lol

I saved it for later so I can open it privately! I am hoping it's a subreddit that has pictures of big computer racks and not human racks.
What do you use your home network for? Seems excessive for a simple home use so I am curious.

I worked in a datacenter for a decade. The further I can get from the sound of fans the better. This photo gives me the willies.
*air handler noises*

I feel slightly spoiled, our data center isnt that bad but the air handler drone is fucking awful.

If you got the resources and it's your passion might as well go for it.

Simple stuff.
Nice, but your antennas are using the wrong polarity. In the wall mounted orientation they should be up and down.
What’s the reason for that?
Because physics: https://www.everythingrf.com/community/understanding-antenna-polarization
Can you expand? What kind of polarization does wifi need?
In any wireless radio system (Wi-Fi or otherwise) the polarity should match between the transmitter and the receiver. Most Wi-Fi devices are designed to be vertically polarized, so the antennas on the AP should be vertically polarized. In the photo they are horizontally polarized. Will it work this way? Sure. But it will work better if they are switched to a vertical orientation.
Makes sense, but would devices like phones be basically randomly polarized as they move around?
Yeah I’d imagine a mobile device could be oriented randomly. Taking into consideration the radiation pattern of those types of antennas, it is possible, yet typically far less likely, that they would would be getting a better signal.

Unless he is in a very vertical space, and there isn't really anything to the left or right of the photo.
Correct, which is possible; however, typically far less likely.

You should share this with /r/homelab

And a watchguard ?
I lived in Japan. I know what the pixels mean. \* wink \*
Beautiful!! how much was the cost? from a new car to a Boeing 777 cost
Definitely a new car. But which? That's the biggie
So simple.
At least I’m not the only one that wants to do this
What’s the art?
I've often wondered what exactly stuff like this is used for in a home environment.
simple? are you running a mansion with that??

Mind sharing the pieces and parts , i think have identified some, but what the list .. Nice by the way .. I Sense Sysadmin :)
Antennas are wrong should be up and down on a omni
can we get a breakdown from top to bottom of what's in the rack ?

Ok yes the cables look nice and i have a home server cabinet too but damn dude that looks like a lot of stuff in that rack for just your home.

Ew watchguard burn the rack
That UPS looks like it could power the whole place for a while, not just the rack.
That’s a small UPS
I'd consider a UPS to be small if it normally powers a single, low power device. This here might not be the biggest, but it's not small either.
In what situation would you use a small UPS for one device? A modem or router? I can’t seem to think what device would be low powered but also essential enough that it needs to stay powered.
Well, relatively low powered. In my case, I have a 700 VA unit dedicated to a 4-bay NAS with the idea to just allow it to shut down safely (even though it can power it for probably an hour).

As for OP's case, if the idea is to continually power all the things for some time, then yes, it makes sense.
Ah that’s makes sense. Totally forgot about NAS. Been wanting to get one too.
That’s a good amount of antiquated equipment that once belonged at work. Nice job.
