That is btw $17,000 Canadian loonies.
Wouldn't you rather use a back up generator or atleast have one in there if you are going to spend $17k just to get maybe 30 mins to work with?
I mean if the power goes out at 4am, hopefully it actually shuts down their servers properly like it said.
this guy buys so much stuff that he so does not need and its amazing :v:
I enjoy watching him break things.
Why did it cost so much. They are lead acid batteries.
I don't understand battery ratings in the way they are using them, but I'm pretty sure a 6k home backup system would do basically the same thing, for a much smaller price tag.

Because its so much more than that. Its a full power management system, not just some shitty home UPS system. I've worked on a far, far bigger one that was insanely more expensive and they're actually really cool.

To be fair, it's kinda his job, what being a tech reviewer and all :v
Now you know which city you shouldnt live in with all the power outages there lol
I guess it doesn't matter much for them, but usually you'd have at least 2 UPS feeding power into your systems, so that if shit breaks, the UPS kicks in, and the second UPS can take over. Two different feeds from two different systems, plus backup generators that can kick in in case one of the power feeds fail.
Otherwise it's just to ensure that the disks don't die, which, tbh, is best secured in different manners through [b]proper[/b] data redundancy.
Someone needs to stage an intervention about those socks and sandals

Yeah, like, I was wondering why he needs all this shit for just one server rack...

The rack IS multiple UPS systems. It all just plugs into the same common backplane.

Actually, now that I look at it I do believe Wal-Mart uses the same UPS system but in a half rack.
Linus is one hell of a weird IT guy.

And also feeds just one power supply, so what use is it, really? I don't see how that really helps.

I'm guessing overall redundancy and it spreads the load among the individual units to make it drain slower. I could be hella wrong.
[QUOTE=EddieLTU;49772083]can't wait until those batteries start to swell[/QUOTE]
I've never seen a lead acid battery swell. I've seen Li-Ion and Li-Po cells swell, but lead acid are pretty tough.

i think the office landlord doesn't allow generators.

It's quite common. Usually however you replace the cells before they get to that point.

I've had to go at rackmount APC systems with a grinder to get the tray out.
[QUOTE=meppers;49772426]i think the office landlord doesn't allow generators.[/QUOTE]
The office park backs onto a residential area.
Also, Linus's operation isn't so mission critical that he needs the servers to remain up at the cost of a $35000 generator. An hour will get him through most interruptions.

You could lose your data a hundred times before the generator would even start.
Keep in mind this isn't some cheapo switching UPS - the servers are always powered by batteries so there is no delay by the switching. If the line is dodgy the switching UPS easily detects something in advance (and also gives a bunch of false positives) but if the power straight up cuts out, a switching ups will make the server lose power momentarily. The delay is why there's also stuff like flywheel UPS systems available - those I believe are used together with generators.
isn't 17k cad like 2 real dollars tho
Ooh, lug this around and your latest and greatest modern smartphone can last for 2 days (3 in battery-saving mode)!
What does the company he works for actually do? Surely this isn't all for youtube.
[QUOTE=credesniper;49772831]What does the company he works for actually do? Surely this isn't all for youtube.[/QUOTE]
Nope, this is literally all he does
When he's not cutting motherboards apart with a dremel to fit incompatible heatsinks onto it (killing three in the process), attempting to make a watercooling loop the size of a room, tearing out the watercooling loop because it's full of mold, or accidentally breaking review hardware, he's sponsored to show off new shit

I'm incredibly confused. Also which video displays this moldy watercooling loop?

APC batteries are notorious for this. Almost every single time I get a call for our APC UPS's I can guarantee they've bulged and this is with batteries that are only like 2-3 years old. You have to physically pry them out because the design of the battery compartment is shit and they get caught on the lip of the compartment. It's fucking terrible. Had one bulge so bad it caused a small scare a car dealership due to the smell it gave off. I could hear it sizzling when I pulled it out.
Never had this shit happen with ONEAC UPS's, even with over 6 year old batteries.

Presumably they also host a bit of stuff as well but yeah, that seems to be it. Frankly you shouldn't run a server without a UPS. It's often an extra $75-$100 more for a simple unit that gives the computer enough time to stop all running tasks, save the RAID cache and power down. Linus however has several beast servers running his famous RAID, the firm's video rendering and export engine and all of their existing content. While his UPS is still wild overkill he still needs something rated for a few thousand watts.

Yep. Simply a massive bank of batteries to keep everything alive while the diesel engine to start and the generator to engage.
