- I promised my wife
that we were not going to do it this way,
but I don't see her.
So here's the thing,
every single project we've ever done
with like multiple gamers,
and one CPU,
or multiple video editors and one CPU,
has had one thing in common,
it was kind of janky.
Good enough to make a video about it for sure,
but not good enough to deploy day to day.
Well today, that all changes.
Both the hardware
and software side of virtualization
have come a long way in the last couple of years,
to the point where we have individual CPUs
with 32 or even 64 cores,
and NVIDIA dropped the artificial lock
on their consumer GeForce GPUs,
that prevented them from running inside a VM
without some hackery nonsense,
not to mention stability issues.
So here's what we're gonna do,
We are gonna build a single OP machine
that is gonna power all five of the gaming stations
in the LAN room over there.
So that my entire family can sit down,
and game together without anybody even realizing
that they're all running on the same box.
- [Jake] We hope
- We hope. Yeah, Jake's here's, sup Jake?
He's holding the script.
- [Jake] It should be fine.
- Kind of adlibbed it a bit.
Oh, just like I adlibbed this segue to our sponsor!

(upbeat music)
- To fill you guys in,
here's what the LAN center's gonna look like.
Each of our five stations is wired up for power.
Oh, that's not power.
Sorry, here's the power.
This one is a Cat6 a cable
connected to an RJ45 connector.
So that can be used for up to 10 gigabit networking.
And then down here,
we've got OM4 multimode fiber with an LC connector,
and we can use this a number of different ways.
The way we are gonna use it is for USB,
but we could actually do up to 100 gigabit networking
on this thing and that's today,
assuming that we don't see any kind of
future evolutions of the standard.
The coolest thing though, is this box up here,
which is actually more of an access box\poll station.
So you can see this runs through conduit in the walls
and would allow us to run different cables in the future.
Also contains this bad boy,
this is a fiber optic Displayport 1.4 cable.
That means that over this single cable that runs
50 feet away to the mechanical room,
we could do 4K 120Hz to a display.
And this will all go back to that motherboard
I was holding at the beginning.
I know all of that is unnecessary.
We could have just as easily put the gaming computers
in the room right next to the monitors.
But the idea was that by using these long distance cables,
we could remove all the heat and all the noise
and just dump it all here in the mechanical room.
- Except it's kind of weird
to just have five, like full size.
I mean, that's kind of small,
but let's say five full size ATX towers
just chilling in here.
So we're like, "Let's throw it in the rack," right?
- Yeah. But then we realized, well, now hold on a second,
just to get a GPU in here without running like.
- Sideways GPS or anything like that.
- Yeah. Freaking like blowing Metron fans
and making a ton of noise,
you're gonna end up with every one of these chassis
being at least this big.
And all of a sudden what, well hold on a second.
Five of these,
we're gonna take up the whole freaking rack.
So I'm sorry, wife.
There was simply no other way than to consolidate all.
- Definitely couldn't have just gotten another
hot pink wreck.
- No, couldn't have done.
I mean, we probably could have done that.
- You don't want to make this one jealous.
- Jake, is that a crypto binding rack?
- Well, yes, yes it is.
Now we don't know what the final system is gonna look like.
- [Linus] Hopefully not like that.
- Yeah. This would not be ideal.
This would not fit in the rack.
Instead, we're just using it to see if the actual concept
of having our five GPUs works well
and works stable enough that you can actually deploy it.
- Cause even though, yeah, like I said,
it's gotten a lot better than it has been over the years.
- We also haven't tried it.
- We haven't tried it on this particular motherboard,
but these particular GPUs
and you can run into some weirdness.
Okay, what's the model of this EPYC in here?
- It's a 75F3, F for frequency.
- And what's special about this bad boy,
is it's 280 watt TDP, 32 cores
and boost frequency of up to four gigahertz.
And as for Ram, okay,
well, you don't get the same kind of crazy specs
that you might on the desktop side
- or RGB,
- Just because you're running server Ram
doesn't mean you need to go slow.
This micron 3,200 mega transfer per second DDR4
is flipping fast and more importantly,
we've got a total of 256 gigabytes of it.
So that means we should be able to put.
- 36 gigs in machine or something?
- Yeah. Six cores to each machine.
- Yeah.
- And 32 gigs of Ram to each machine.
- Easy, yeah.
- Easy.
- I mean, we could give the kids 16
and use the rest for something else.
- That's true.
So one of the greatest things about EPYC
is how many PCIe lanes
are running off of that CPU.
It's 128.
That means that each of these 60 text slots
is actually running at full PCIe 4.0 x16
not that with an asterisk.
So I think there's a couple of them...
- [Jake] There's one.
- One okay.
- There's one that like switches with some twos
or something like that.
- These are OCuLink, these are PCIe.
- Yeah.
- These M.2 will they share,
but they're PCIe and then these are Sata, right?
- [Jake] Yeah. They're like..
- They break out.
- [Jake] Yeah.
- But you still got that's another eight lanes
right over there, there's fricking insane.
Okay, when I saw these, I just about crapped my pants,
but sonnet has a new USBC card.
- Okay.
Isn't that amazing?
Each of these two ports
is powered by a dedicated controller,
here on this board
that appears to be using an M.2 connector.
- [Jake] Yeah.
To split So they must have some kind of PCIe switch
or bridge chip on here or something like that.
So you can take the 16X lane and get,
I guess, anywhere from,
that's weird actually.
It's a 16X interface here
and then they've got only a 4X.
- Well, if you look at the board too,
like it doesn't really look like
the rest of the pins are connected.
- Okay, this is an 8X board.
And then they've just got it
taking up a full 16X slot just for lulls, apparently.
Anyway, the reason we need these
are that you can pass through an individual USB device
or USB port to a VM,
but the better way to do it
without compromising on performance,
is to pass through an entire controller.
So this way each one of our Vms
is gonna get its own controller.
That way we can have full hot plug capabilities
and full performance, if for whatever reason they're doing,
I don't know, homework or a media project on there
or something, they wanna ingest some footage.
- Yeah. It's kind of like... - Boom,
you know, a regular computer with just a USB port.
You can just use it just like that.
- Exactly. And once you've got display port and USB,
you can kind of connect to anything.
Do you have a particular layout plan for this?
- Sort of, I played with it a bit
and there is a way that makes it work better,
otherwise known as there's only one way to do it.
And if you don't do it this way, it won't all fit.
- Okay, and do you remember?
Thanks Jake.
For the kids, we've got RTX 3060s.
These are actually the ones that are left over or returned
from the verified actual gamer drop.
And we just tested to make sure they work.
Cause they are returns.
- Should be fine. - Nop.
- Okay, sure.
Anyway, the point is we only got a handful of them back
and so it wasn't enough for us to have
any meaningful amount of stock to do a drop again.
But we didn't wanna just turn around
and sell them individually
and like profit off the scalper prices or whatever.
So they've kind of just been sitting there.
Anyway, now we're gonna use them. So there you go.
Three 3060s, and then for me in Yvonne,
we're stepping up for two 38 DTIs
cause like, you know, we're the parents,
we get the good stuff.
We'll probably swap these out when we do the final...
- I think the intention long term
would be to water cool them.
So we might end up with reference cards
just to make that a little bit easier.
- Right, yeah.
- Do you remember when an AX1600i was like excessive?
- Like stupid.
- You could run four GPUs on it
now you're like you could run two maybe
like can you even run two 3090s on an AX1600i?
- Yeah, yeah.
- Yeah but it's still like, "Ooh, you're getting there."
- It's fine, it's fine.
- So for five we needed more than one power supply.
I wanted to use the 2,000 watt power supply We have,
cause you do have 208 volt in the rack.
- Oh that's right.
But we don't have an extension cord to get that power
from there to here.
- Right. And we're doing the tests out here
rather than running everything through the walls today.
- Yeah.
- We wanna know if it actually works.
- Instead rather than one AX1600i, we have two nerd.
I got a little power supply jumper,
these things are sick.
You just plug it into your motherboard
and it's got a little like pig tail
with two connections just to jump the power supply.
So when you hit the button,
they both turn on at the same time.
You don't have to do this,
you could put a paperclip in the second power supply
and it would just be on all the time.
But it doesn't really feel right, you know.
- Yeah, that doesn't feel right at all.
- Oh, one thing we didn't mention
we're running unRAID
so our operating system runs off of a USB stick
like it's the stone age, lime tech.
If you guys are watching,
definitely do wanna be able to run unRAID
off of a real drive at some point. Thank you.
- Can I turn this on now?
- Whoa, hold on a second there by, oh you just.
- Gotta plug IOS that's VGA,
that stuff works live, it's fine.
- Yeah. Well, no, I just, it's not the point.
- I just gonna...
- Do you know which...
- Turning it on?
- Woo.
- Which one's manages which one's 10 gig? Yeah.
- Hey look. it's booting
- It's booting?
- Yeah. - Oh good.
- Look at that.
- Why do these server boards ever take a long time to boot?
- Well, they have to wait for the IPMI to boot up.
I was having a panic attack this morning.
It was booting up,
you see this monitor down here?
The main monitor was only showing PCIe bus enumeration,
which means like it's checking for the graphics cards.
But it also means that it's gone to the graphics card
to display the output.
But I had set in the bios before
to just use the VGA port on the motherboard.
- Right. So just ignored you.
- Yeah
- Cause it's a server board doing server board things.
- And I was like, oh God, this computer's not working.
Oh my God, the shoot's gonna be a sham.
Oh my God, they're already on their way.
Oh my God, oh my God.
And then the internet stopped working.
It was a stressful morning, but it works.
- Yeah. Oh what...
- Can we talk about the fact that
we just hooked up like five GPUs on PCIe risers
with two USB because that's seven cards into the system.
It just turned right on.
The only thing I changed in the bio
was that setting that it ignored, so.
- That's insane.
- It's a lot of learn here.
- Previous projects like this,
we're talking multiple days
just to get the computer to turn on
with everything plugged in.
- I see for storage, we've gone with.
- One, it's.
- A single one terabyte SSD.
We could do way better than that in the future.
We could set up some kind of array or.
- Actually you have a ZFS pool.
- Yeah, do they have ZFS pool supported yet?
- No, I don't think so.
- Add pool. What is this add pool?
- That's just to add, you can have multiple cash pools now,
which is kind of cool, but.
- Okay, that's neat.
They are apparently working on ZFS
so that would be amazing.
- You can also do it with like a third party plugin.
- Hey, look at that, nice.
- I wonder which GPU that is.
- Quick start mining doge coin.
- So this is a 3060?
- 3060, okay.
- Let's see. Does it work?
Oh yeah, she works good.
- Yeah, that looks great.
- [Jake] I have two screens.
Okay. Let's try GPU two then.
- Can I get you chair Jake?
- No.
- I'm gonna get a chair
and he's gonna just refuse to sit on it,
because he's stubborn
cause now he said that he doesn't need a chair.
So I'm gonna put this right here, you watch.
- Hey, let's though, Hagrid.
- World's more comfortable,
he's not gonna sit in it.
- You and your chair can just go (beep) yourself.
- Ah, ah, yeah.
- Yeah, yeah. That's what I thought.
- We got I. Hey nice.
So that's two for two.
- That's a 3080 DTI.
Isn't it insane how easy this is?
You used to have to fight like error 43.
Cause they were trying to detect that you were in a VM.
Like just.
- Yeah.
- For lack of a better word go (beep) yourself.
- The video.
- Yeah.
- I mean they're doing it better now.
There's still things they could do way better though.
- Yeah.
- Let's see. I'm gonna boot up.
I'm booting up another VM. Don't touch it.
- Look at that. Hey, hey, hey
- I'm not touching.
- Hey. Hey. - Okay. I believe you
- Look, look.
- Okay. Oh my God.
- Hey look, look.
- It's like when a small child
like goes to the bathroom by themself.
- No, no, but I want you to watch me do it.
- Hey Linus I had a really nice poop this morning.
- I'm glad to hear it, Jake.
I really am pleased for you.
- It Was one long.
Hey look, hey Linus, look.
- Oh my God, yes.
- Look, look.
It's working.
- Yay job.
- Yay.
- Okay.
- How about for real though?
- Cool, that it's working.
- There's four of them. Okay.
- What about number five?
- How sure are you that it's this boy?
- It's this boy because the fans are still spinning.
- No, I meant how do you know it's this boy that's working,
but yeah. Okay, sure.
So they it's running, it's silent mode.
So the fans are actually completely off
on all the ones that are working correctly.
- Well, this is in.
- Brother, what? The power supplies are still on.
- They are.
- Yes.
- I don't know, the other fans are off.
- The power supplies though.
- Oh, yeah. But the power supplies,
they like power, they need power.
It's right in the name.
- It, has stops working because of that,
not my fault. Oh wait, what slot is that?
Is that second from the bottom?
- Yes.
- Oh. - Oh.
- We might have to move the jumper, it might be in.
- Right. Under T mode.
- Yeah.
- Okay. Well that's fine.
That's doable. Is it a jumper?
Or is it a bio setting?
- It's a jumper.
- Really?
- Yeah.
- Oh what year is it? Has for rock crack.
- There's two jumpers for it.
They should both be on the left.
What are the odds that this just works?
I just wanna,
I'm gonna say right now full disclosure.
I did not test this with five GPS
before I just assumed it would work.
- Freaking guy.
- I tested it with two and it worked so well.
And I did check that all the PCIe slots work
except those ones, so.
- Yeah, okay.
- Oh boy.
- What's up? What's up?
- I'm setting the last VM.
- Okay.
- I'm gonna start the rest of them.
- Okay. Are you gonna full Yolo and start them all at once?
- Yeah. That's what I'm doing right now.
- Nice.
- It's literally happening as we speak.
Oh, oh there's three.
There's four, there's five. Woo.
- I'm actually really surprised.
- Yeah. So easy.
And the cool thing is I can access them all
on the VNC still.
- Man, this is hardly even a video
cause everything's going so smoothly.
I need to create some drama.
Oh no, Jake's chair failed.
- You mean your chair failed?
- Oh yeah. Right, no.
Okay, it's a good chair.
This quality chair, Aluminum chair.
Once you're going fast enough.
Downloading games on steam is actually pretty demanding.
We are sucking back.
What does this work out to?
26% of this 32 core processor.
And I think only two of them are actually
downloading right now.
Lasting two FA code.
Sorry, we needed five freaking accounts with CS:Go.
- We still don't know if you want CS:Go.
- No, no. She has CS:GO.
I told you she's got CS:GO.
- Okay, cool.
She doesn't have CS:GO.
- She doesn't have CS:GO.
Not a different game then, I don't even care anymore.
- Yeah, just it doesn't have to be the same game.
- Yeah, whatever.
CoD modern warfare 2.
- Halo
- Halo inifitive. Yeah.
Heck yeah.
- Let's do it.
Okay, but hey.
Oh my goodness, look at these CPU's going.
There's your halo?
Infinite download boys.
Does that happen to be VM number two?
- I mean, I guess it probably is.
I mean, there's no way it's not.
- What speed is it managing to do?
- 129 Megabytes a second.
- Okay, that's not bad.
- I think steam uses Z standard compression now.
So pretty quick.
- Wow, we're gonna need more Chos dude.
- We are. I can actually see that,
it's not running amazing.
All things considered and mind you,
all of these are running bots,
which is pretty CPU intensive, but still pretty damn good.
- It's running.
- Honestly, if we switched the storage to something faster,
it would actually probably make the performance better.
- I suspect storage is a big, big problem right now.
Oh, interesting.
This one is seeing up to 200 FPS now.
- That one in the bottom right is just like.
- 30, 40, 50.
This one's all over the place.
It's going up to like 250
and then dropping down to I saw it as low as 50.
And that happened to correspond with a peak
and download speed over here.
We are almost definitely just storage limited.
And I bet when we throw better storage in here,
it's just gonna resolve it.
- I mean the CPU usage is pretty high right now.
It's like doing a lot of stuff.
- That's true, but it's not that bad.
I think. I don't think that's it.
You wanna make a friendly wager lunch?
- No.
- All right, it was worth a shot.
I like free lunch.
Hello, hello Infinite, are you gonna launch?
- Hello buddy.
Hello buddy?
Hey, there we go.
Wait, and it's gone.
- God damn it. We should have just bought CS:GO.
- Okay. We got our fifth game launch, we just need.
- I mean that pretty much confirms it.
We got five, mostly working gaming computer stations.
- Yeah. We've just got some storage issues to figure out,
get all of the five optics,
actually connected to monitors and put desks in there
and everything.
- There's probably some optimization to be done.
- But that's it, single machine five gaming stations.
I think this is probably good enough for prime time.
- This is the easiest virtualization setup I've ever done.
- And this is the easiest segue I've ever done.
