1
00:00:00,160 --> 00:00:05,359
we've done a lot of content using lime

2
00:00:03,240 --> 00:00:10,080
Tech's unraid operating system over the last little while some of it was focused

3
00:00:07,560 --> 00:00:14,080
on the safe redundant storage features of it like this one about repurposing

4
00:00:12,120 --> 00:00:18,840
older computer hardware to build a more robust NZ while some of it was more

5
00:00:16,760 --> 00:00:24,359
focused on the virtualization features of un raid that allow multiple virtual

6
00:00:21,920 --> 00:00:30,480
computers we've demoed as many as seven discrete gaming rigs at a time to live

7
00:00:27,119 --> 00:00:32,759
on top of that safe redundant storage

8
00:00:30,480 --> 00:00:37,440
but while we've discussed how cool that is and demonstrated really strong

9
00:00:35,239 --> 00:00:43,360
performance with these VMS or virtual machines we haven't Quantified Apples to

10
00:00:40,520 --> 00:00:49,360
Apples how they compare with running the operating system software directly on

11
00:00:46,239 --> 00:00:51,260
the hardware or the bare metal so let's

12
00:00:49,360 --> 00:00:56,209
do that today then shall

13
00:00:58,600 --> 00:01:05,000
we the G gtx980ti VR Edition from EVGA

14
00:01:03,160 --> 00:01:09,840
provides an industry-leading Graphics experience as well as a 5 and a/4 in Bay

15
00:01:07,640 --> 00:01:14,720
with easy access inputs for your VR device learn more at the link in the

16
00:01:12,080 --> 00:01:20,560
video description so I think we should open with a primer on what this word

17
00:01:17,960 --> 00:01:24,560
virtualization really means those of you who are intimately familiar with it can

18
00:01:22,360 --> 00:01:29,320
skip ahead because Taran gave me a hard time after we filmed the quadruple your

19
00:01:26,479 --> 00:01:32,040
networking Speed video about not really explaining what I was talking about and

20
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

21
00:01:35,159 --> 00:01:44,360
video so let's start with an analogy this is a gigabit network interface card

22
00:01:40,920 --> 00:01:46,000
or Nick it's physical because I can hold

23
00:01:44,360 --> 00:01:49,600
it in my hand and it's a network interface card because it connects

24
00:01:47,560 --> 00:01:54,399
whatever it's plugged into into a network and allows those two things to

25
00:01:51,759 --> 00:01:58,799
communicate or interface with each other at a speed of 1 gigabit or about 110

26
00:01:57,000 --> 00:02:05,840
megabytes per second pretty straightforward a virtual Nick is

27
00:02:02,360 --> 00:02:07,799
inherently more abstract while it does

28
00:02:05,840 --> 00:02:11,760
still require some Hardware I mean without a physical cable plugged into

29
00:02:09,599 --> 00:02:16,440
something it can't connect to a device outside of the machine on which it

30
00:02:13,239 --> 00:02:19,239
resides and in most cases it presents

31
00:02:16,440 --> 00:02:25,920
itself to the operating system as though it is a piece of Hardware it's actually

32
00:02:22,720 --> 00:02:28,560
just some clever software pretending to

33
00:02:25,920 --> 00:02:34,360
be Hardware which gives it some cool functionality not the least of which is

34
00:02:30,920 --> 00:02:36,800
that it is able to share its resources

35
00:02:34,360 --> 00:02:42,159
so back to our physical Nick again it's got that gigabit connection speed I

36
00:02:38,840 --> 00:02:45,440
talked about before well by creating two

37
00:02:42,159 --> 00:02:49,000
virtual Nicks we can actually share that

38
00:02:45,440 --> 00:02:51,840
speed between virtual devices like I did

39
00:02:49,000 --> 00:02:57,800
in the gaming Naas video where we had both a file server and a gaming machine

40
00:02:55,080 --> 00:03:02,720
using the same network connection so this is a very flexible solution because

41
00:03:00,040 --> 00:03:08,760
it means that either of these devices can use anywhere from zero all the way

42
00:03:05,440 --> 00:03:11,519
to 100% of the available resources

43
00:03:08,760 --> 00:03:16,640
sharing them dynamically and thanks to some really cool Tech from Intel and AMD

44
00:03:14,200 --> 00:03:22,680
this can even be done on things like CPUs meaning that you can create entire

45
00:03:19,760 --> 00:03:28,319
virtual computers full of virtual devices that share physical Resources

46
00:03:25,440 --> 00:03:33,519
with each other for better overall efficiency cool minus but what was up

47
00:03:31,080 --> 00:03:38,680
with that big asterisk a minute ago well the KVM kernel-based virtual machine

48
00:03:36,280 --> 00:03:44,040
project at red hat which is what unraid is using to power its virtualization is

49
00:03:41,239 --> 00:03:51,280
some pretty freaking impressive software but virtual devices do not have 100% of

50
00:03:48,519 --> 00:03:56,439
the performance of the physical devices because while the days of emulation

51
00:03:53,840 --> 00:04:02,280
that's a very slow way of doing this virtual device stuff are basically over

52
00:03:59,840 --> 00:04:06,439
there is still some overhead involved which thank you for your patience by the

53
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

54
00:04:11,879 --> 00:04:20,160
performance are we giving up when we do a project like gaming NZ or seven Gamers

55
00:04:17,160 --> 00:04:22,440
one CPU so for this test I actually

56
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

57
00:04:24,400 --> 00:04:32,680
test bench at the office but the good news is that with its 5960x Rampage 5

58
00:04:29,199 --> 00:04:35,360
extreme 99 motherboard gtx980ti and 64

59
00:04:32,680 --> 00:04:40,759
gigs of Dominator memory my rig is pretty much the same as my usual test

60
00:04:37,520 --> 00:04:43,479
bench so I started then by establishing

61
00:04:40,759 --> 00:04:50,240
my Baseline performance I ran my test Suite with all eight cores active then I

62
00:04:46,520 --> 00:04:52,280
used the BIOS to turn off one of the

63
00:04:50,240 --> 00:04:57,919
physical cores on the CPU making it effectively a s core this was done

64
00:04:55,520 --> 00:05:04,199
because for the best performance on unraid anyway in games it's best to

65
00:05:01,199 --> 00:05:06,120
leave a core aside for unraid to use and

66
00:05:04,199 --> 00:05:11,720
give everything else to your virtual machine and while gaming actually didn't

67
00:05:09,199 --> 00:05:16,840
end up being affected negatively at all I mean these results are within my

68
00:05:13,720 --> 00:05:19,400
margin of error for these tests this was

69
00:05:16,840 --> 00:05:24,720
expected since games are not very CPU bound these days and the video card

70
00:05:21,639 --> 00:05:27,720
itself is actually passed through as a

71
00:05:24,720 --> 00:05:29,720
physical device to the virtual machine

72
00:05:27,720 --> 00:05:35,080
cinebench also showed the same result results our virtual 7 core and our bare

73
00:05:32,000 --> 00:05:37,680
metal 7 core performed the same leaving

74
00:05:35,080 --> 00:05:44,000
the only test that showed a dramatic difference being the synthetic memory

75
00:05:40,039 --> 00:05:46,759
and cache test in Ida 64 so depending on

76
00:05:44,000 --> 00:05:52,600
the workload it is possible that these extra Nan of additional latency could be

77
00:05:50,360 --> 00:05:57,039
a problem but from looking at performance in consumer oriented

78
00:05:54,680 --> 00:06:02,720
workloads it seems like we are pretty darn close to a VM being a Sol solid

79
00:05:59,919 --> 00:06:08,240
alternative to running straight on the hardware now then it's just got to get a

80
00:06:05,960 --> 00:06:13,440
little bit easier for everyday people to do because while some of the benefits uh

81
00:06:11,360 --> 00:06:18,800
virtualizing servers to consolidate functionality are more applicable to the

82
00:06:16,199 --> 00:06:24,199
data center there is some really cool stuff that I can Envision for a consumer

83
00:06:21,080 --> 00:06:25,960
facing product like unraid as well with

84
00:06:24,199 --> 00:06:32,639
the gaming Naz we did a little while back being just the tip of the iceberg

85
00:06:29,800 --> 00:06:39,039
tunnel bear is the easy to usee VPN app for mobile and desktop it lets you

86
00:06:35,000 --> 00:06:41,160
tunnel so to speak into up to 20

87
00:06:39,039 --> 00:06:45,360
different countries allowing you to browse the internet and use online

88
00:06:43,160 --> 00:06:49,840
services as though you are in a different country so you know let's say

89
00:06:47,919 --> 00:06:55,120
for example you want to access a website that is blocked in your country or you

90
00:06:52,080 --> 00:06:56,960
want to access a service that is just

91
00:06:55,120 --> 00:07:01,599
plain not available in your country due to licensing or whatever else ha screw

92
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

93
00:07:03,919 --> 00:07:09,879
Chrome extension they're super easy to use just pick a country press the

94
00:07:08,000 --> 00:07:13,199
friendly looking button and boom your connection gets encrypted which by the

95
00:07:11,400 --> 00:07:17,800
way tunnel bear doesn't actually log any of your activity which is very cool and

96
00:07:15,199 --> 00:07:21,319
your public IP address gets switched so you show up as though you're in a

97
00:07:19,440 --> 00:07:27,960
different country and the best part of tunnel bear is that your first 500

98
00:07:23,199 --> 00:07:30,080
megabytes is absolutely free w and after

99
00:07:27,960 --> 00:07:35,720
that the unlimited plans are very reasonably priced so check it out at the

100
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

101
00:07:37,919 --> 00:07:45,080
link that's tunnel bear.com LT so thanks for watching guys if you
