00:00:00.160 --> 00:00:05.359
we've done a lot of content using lime

00:00:03.240 --> 00:00:10.080
Tech's unraid operating system over the last little while some of it was focused

00:00:07.560 --> 00:00:14.080
on the safe redundant storage features of it like this one about repurposing

00:00:12.120 --> 00:00:18.840
older computer hardware to build a more robust NZ while some of it was more

00:00:16.760 --> 00:00:24.359
focused on the virtualization features of un raid that allow multiple virtual

00:00:21.920 --> 00:00:30.480
computers we've demoed as many as seven discrete gaming rigs at a time to live

00:00:27.119 --> 00:00:32.759
on top of that safe redundant storage

00:00:30.480 --> 00:00:37.440
but while we've discussed how cool that is and demonstrated really strong

00:00:35.239 --> 00:00:43.360
performance with these VMS or virtual machines we haven't Quantified Apples to

00:00:40.520 --> 00:00:49.360
Apples how they compare with running the operating system software directly on

00:00:46.239 --> 00:00:51.260
the hardware or the bare metal so let's

00:00:49.360 --> 00:00:56.209
do that today then shall

00:00:58.600 --> 00:01:05.000
we the G gtx980ti VR Edition from EVGA

00:01:03.160 --> 00:01:09.840
provides an industry-leading Graphics experience as well as a 5 and a/4 in Bay

00:01:07.640 --> 00:01:14.720
with easy access inputs for your VR device learn more at the link in the

00:01:12.080 --> 00:01:20.560
video description so I think we should open with a primer on what this word

00:01:17.960 --> 00:01:24.560
virtualization really means those of you who are intimately familiar with it can

00:01:22.360 --> 00:01:29.320
skip ahead because Taran gave me a hard time after we filmed the quadruple your

00:01:26.479 --> 00:01:32.040
networking Speed video about not really explaining what I was talking about and

00:01:31.000 --> 00:01:37.840
I was kind of like well it's kind of like SLI for networking and he's like well why didn't you just say that in the

00:01:35.159 --> 00:01:44.360
video so let's start with an analogy this is a gigabit network interface card

00:01:40.920 --> 00:01:46.000
or Nick it's physical because I can hold

00:01:44.360 --> 00:01:49.600
it in my hand and it's a network interface card because it connects

00:01:47.560 --> 00:01:54.399
whatever it's plugged into into a network and allows those two things to

00:01:51.759 --> 00:01:58.799
communicate or interface with each other at a speed of 1 gigabit or about 110

00:01:57.000 --> 00:02:05.840
megabytes per second pretty straightforward a virtual Nick is

00:02:02.360 --> 00:02:07.799
inherently more abstract while it does

00:02:05.840 --> 00:02:11.760
still require some Hardware I mean without a physical cable plugged into

00:02:09.599 --> 00:02:16.440
something it can't connect to a device outside of the machine on which it

00:02:13.239 --> 00:02:19.239
resides and in most cases it presents

00:02:16.440 --> 00:02:25.920
itself to the operating system as though it is a piece of Hardware it's actually

00:02:22.720 --> 00:02:28.560
just some clever software pretending to

00:02:25.920 --> 00:02:34.360
be Hardware which gives it some cool functionality not the least of which is

00:02:30.920 --> 00:02:36.800
that it is able to share its resources

00:02:34.360 --> 00:02:42.159
so back to our physical Nick again it's got that gigabit connection speed I

00:02:38.840 --> 00:02:45.440
talked about before well by creating two

00:02:42.159 --> 00:02:49.000
virtual Nicks we can actually share that

00:02:45.440 --> 00:02:51.840
speed between virtual devices like I did

00:02:49.000 --> 00:02:57.800
in the gaming Naas video where we had both a file server and a gaming machine

00:02:55.080 --> 00:03:02.720
using the same network connection so this is a very flexible solution because

00:03:00.040 --> 00:03:08.760
it means that either of these devices can use anywhere from zero all the way

00:03:05.440 --> 00:03:11.519
to 100% of the available resources

00:03:08.760 --> 00:03:16.640
sharing them dynamically and thanks to some really cool Tech from Intel and AMD

00:03:14.200 --> 00:03:22.680
this can even be done on things like CPUs meaning that you can create entire

00:03:19.760 --> 00:03:28.319
virtual computers full of virtual devices that share physical Resources

00:03:25.440 --> 00:03:33.519
with each other for better overall efficiency cool minus but what was up

00:03:31.080 --> 00:03:38.680
with that big asterisk a minute ago well the KVM kernel-based virtual machine

00:03:36.280 --> 00:03:44.040
project at red hat which is what unraid is using to power its virtualization is

00:03:41.239 --> 00:03:51.280
some pretty freaking impressive software but virtual devices do not have 100% of

00:03:48.519 --> 00:03:56.439
the performance of the physical devices because while the days of emulation

00:03:53.840 --> 00:04:02.280
that's a very slow way of doing this virtual device stuff are basically over

00:03:59.840 --> 00:04:06.439
there is still some overhead involved which thank you for your patience by the

00:04:04.120 --> 00:04:14.239
way brings us finally to the topic for today how much of our raw or bare metal

00:04:11.879 --> 00:04:20.160
performance are we giving up when we do a project like gaming NZ or seven Gamers

00:04:17.160 --> 00:04:22.440
one CPU so for this test I actually

00:04:20.160 --> 00:04:26.479
ended up using my personal rig because I had to work on it at home and I left my

00:04:24.400 --> 00:04:32.680
test bench at the office but the good news is that with its 5960x Rampage 5

00:04:29.199 --> 00:04:35.360
extreme 99 motherboard gtx980ti and 64

00:04:32.680 --> 00:04:40.759
gigs of Dominator memory my rig is pretty much the same as my usual test

00:04:37.520 --> 00:04:43.479
bench so I started then by establishing

00:04:40.759 --> 00:04:50.240
my Baseline performance I ran my test Suite with all eight cores active then I

00:04:46.520 --> 00:04:52.280
used the BIOS to turn off one of the

00:04:50.240 --> 00:04:57.919
physical cores on the CPU making it effectively a s core this was done

00:04:55.520 --> 00:05:04.199
because for the best performance on unraid anyway in games it's best to

00:05:01.199 --> 00:05:06.120
leave a core aside for unraid to use and

00:05:04.199 --> 00:05:11.720
give everything else to your virtual machine and while gaming actually didn't

00:05:09.199 --> 00:05:16.840
end up being affected negatively at all I mean these results are within my

00:05:13.720 --> 00:05:19.400
margin of error for these tests this was

00:05:16.840 --> 00:05:24.720
expected since games are not very CPU bound these days and the video card

00:05:21.639 --> 00:05:27.720
itself is actually passed through as a

00:05:24.720 --> 00:05:29.720
physical device to the virtual machine

00:05:27.720 --> 00:05:35.080
cinebench also showed the same result results our virtual 7 core and our bare

00:05:32.000 --> 00:05:37.680
metal 7 core performed the same leaving

00:05:35.080 --> 00:05:44.000
the only test that showed a dramatic difference being the synthetic memory

00:05:40.039 --> 00:05:46.759
and cache test in Ida 64 so depending on

00:05:44.000 --> 00:05:52.600
the workload it is possible that these extra Nan of additional latency could be

00:05:50.360 --> 00:05:57.039
a problem but from looking at performance in consumer oriented

00:05:54.680 --> 00:06:02.720
workloads it seems like we are pretty darn close to a VM being a Sol solid

00:05:59.919 --> 00:06:08.240
alternative to running straight on the hardware now then it's just got to get a

00:06:05.960 --> 00:06:13.440
little bit easier for everyday people to do because while some of the benefits uh

00:06:11.360 --> 00:06:18.800
virtualizing servers to consolidate functionality are more applicable to the

00:06:16.199 --> 00:06:24.199
data center there is some really cool stuff that I can Envision for a consumer

00:06:21.080 --> 00:06:25.960
facing product like unraid as well with

00:06:24.199 --> 00:06:32.639
the gaming Naz we did a little while back being just the tip of the iceberg

00:06:29.800 --> 00:06:39.039
tunnel bear is the easy to usee VPN app for mobile and desktop it lets you

00:06:35.000 --> 00:06:41.160
tunnel so to speak into up to 20

00:06:39.039 --> 00:06:45.360
different countries allowing you to browse the internet and use online

00:06:43.160 --> 00:06:49.840
services as though you are in a different country so you know let's say

00:06:47.919 --> 00:06:55.120
for example you want to access a website that is blocked in your country or you

00:06:52.080 --> 00:06:56.960
want to access a service that is just

00:06:55.120 --> 00:07:01.599
plain not available in your country due to licensing or whatever else ha screw

00:06:59.360 --> 00:07:05.879
that because they've got apps for iOS Android PC and mac and they also have a

00:07:03.919 --> 00:07:09.879
Chrome extension they're super easy to use just pick a country press the

00:07:08.000 --> 00:07:13.199
friendly looking button and boom your connection gets encrypted which by the

00:07:11.400 --> 00:07:17.800
way tunnel bear doesn't actually log any of your activity which is very cool and

00:07:15.199 --> 00:07:21.319
your public IP address gets switched so you show up as though you're in a

00:07:19.440 --> 00:07:27.960
different country and the best part of tunnel bear is that your first 500

00:07:23.199 --> 00:07:30.080
megabytes is absolutely free w and after

00:07:27.960 --> 00:07:35.720
that the unlimited plans are very reasonably priced so check it out at the

00:07:32.919 --> 00:07:40.440
link in the video description and uh by the way you can save 10% by using that

00:07:37.919 --> 00:07:45.080
link that's tunnel bear.com LT so thanks for watching guys if you
