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 kinda 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 land 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 we hope we hope yeah Jake's here what's up
Jake he's holding the script should be fine kind of ad-libbed it a bit
oh just like i ad-libbed this segway to our sponsor smart deploy now powered by
pdq.com with smart deploy it professionals can leverage box dropbox

Linus
to fill you guys in here's what the land center is going to 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 cat 6a 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 multi-mode fiber with an lc connector and we can use this
a number of different ways the way we're going to 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 pull
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 120 hertz 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 just chilling in here so we're like let's throw it in the rack
yeah but then we realized well now hold on a second
just to get a GPU in here without running like sideways gpus yeah freaking
like uh blowing matron fans and making a ton of noise you're gonna end up with
every one of these chassis being at least this thick and all of a sudden
we'll 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 it 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 mining rack why yes yes it is now we don't know what the final system is
gonna look like um 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 work stable enough that you can
actually deploy it because 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 you haven't
tried it on this particular motherboard with these particular gpus and you can
run into some weirdness okay what's the model of this epic in here 75 f3 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 3200 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 of machine or something yeah six
cores to each machine yeah and 32 gigs of RAM to each pc yeah easy we could
give the kids 16 and use the rest for something else that's true so one of the
greatest things about epic is how many pci elaines are running off of that CPU
it's 128 that means that each of these 60 text
slots is actually running at full PCIe gen four by 16. not but with an asterisk
so i think there's a couple of them no there's one one one that like switches
with some m.2s or something like that these are oculink these are PCIe yeah
these m.2 is well they share but they're PCIe and then these are SATA right yeah
they break out yeah but you still got that's another eight lanes right over
there that's freaking 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 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 these
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 going to 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 want to ingest something 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
displayport and usb you can kind of connect to anything do you have a
particular layout planned 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 um
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 uh have we tested to make sure they work because they are returns should be
fine 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 want to 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 going to use them so there you go uh three 30 60s
and then for me and Yvonne we're stepping up to 38 etis because
like you know we're the parents we get the good stuff we'll probably swap these
out when we do the finals 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 ax 1600i was like
excessive like stupid you could run four gpus on it now you're like you could run
two maybe can you even run two thirty nineties on an ax1600i yeah yeah yeah
but it's still like oh you're getting there it's it's fine it's fine so for
five we needed more than one power supply i wanted to use the 2000 watt
power supply we have because 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 test out here rather than running everything through the
walls today yeah we want to know if it actually works instead rather than one
ax1600i we have two nerd i got a little little power supply
jumper these things are sick you just plug it into your motherboard and it's got a little like pigtail 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 paper clip in the second power supply and it
would just be on all the time but it doesn't really feel right 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 want to be able to run on raid off of
a real drive at some point thank you can i turn this on now oh hold on a second
there buddy that's vga that stuff works live yeah
well no i just it's not the point i'm just gonna you know
yeah hey look it's boot it's booty yeah oh good look at that
boy 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 i just ignored you because it's a server board doing server boards and i was like oh god this
computer's not working oh my god the shoot's going to 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 can we talk about the fact that we just hooked up like five
gpus on PCIe risers with two usb cards
so that's seven cards into the system and just turned right on
the only thing i changed in the BIOS was that setting that it ignored so
yeah that's insane so that'll learn yeah
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 a single one terabyte SSD we could do
way better than that in the future we can set up some kind of array or give us
a set of festivals yeah do they have zfs pool supported yet i don't think so add
pool what does this have to do that's just to add you can have multiple cache pools now which is kind of cool about
that 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 plug-in hey look at that
nice i wonder which GPU that is click start mining dogecoin so this is a 30 60
30 60. okay let's see does it work oh yeah she works
good yeah that looks great two screens okay let's try a GPU too then can i get
you a chair Jake no i'm gonna get a chair and he's gonna
just refuse to sit on it because he's stubborn because now he said that he
doesn't need a chair so i'm just i'm going to put this right
here hey you watch even though you're hagrid world's more comfortable he's not
going to sit in it you and your chair can just go ah
yeah yeah yeah that's what i thought we got it hey
nice so that's two for two that's a 38 dti isn't it insane how easy this is you
used to have to fight like error 43 because they were trying to detect that
you were in a vm like just yeah for lack of a better word go
yourself yeah 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 you oh look at that i'm not hey hey okay i love you
guys okay hey guys hey look why is this
look it's like when a small child like goes to the bathroom by themselves 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 oh my god yes look look
good job yay
okay but 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 way that's working but yeah okay sure so
it's running it's 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 and all the other fans are off the power is that oh yeah but the
power supplies they like power they need power it's right in the name if this
stops working because of that not my fault oh wait what slot is that is that
second from the bottom yes oh we might have to move the jumper it
might be in mode yeah
okay well that's fine that's doable is it a jumper or is it a BIOS setting it's
a jumper really yeah oh what year is it ask for our 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 gpus before i just assumed it would work
you 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 go 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 there's three there's four there's five
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 because everything's going so smoothly i need to create some
drama oh no Jake's chair failed
i mean your chair fell oh yeah right no okay it's a good chair it's 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 last steam 2fa code sorry we needed five freaking accounts with cs go
we still don't know if you want scs no no she has cs go i told you she's got
csgo okay cool she doesn't have csgo she doesn't have csgo
what a different game then i don't even care anymore yeah i guess it doesn't have to be the same game yeah whatever
cod modern warfare 2. halo isn't it yeah
heck yeah let's do it okay but hey oh my
goodness look at these cpus going there's your halo infinite download boys
does that happen to be vm number two i i mean i guess it probably is what 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 wow we're gonna need more cores dude
we are i can actually see that it's it's not running amazing all things
considered mind you all of these are running bots which is pretty CPU
intensive but still pretty damn good
it's running honestly if we switch 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 in 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 is pretty high right
now it's like doing a lot of stuff that's true but that's not that bad i
think i don't think that's it you want to make a friendly wager lunch no
all right it was worth a shot i like free lunch uh hello hello infinite are
you going to launch 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 launched 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 fiber
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
