we've done a lot of content using lime
Tech's unraid operating system over the last little while some of it was focused
on the safe redundant storage features of it like this one about repurposing
older computer hardware to build a more robust NZ while some of it was more
focused on the virtualization features of un raid that allow multiple virtual
computers we've demoed as many as seven discrete gaming rigs at a time to live
on top of that safe redundant storage
but while we've discussed how cool that is and demonstrated really strong
performance with these VMS or virtual machines we haven't Quantified Apples to
Apples how they compare with running the operating system software directly on
the hardware or the bare metal so let's
do that today then shall
we the G gtx980ti VR Edition from EVGA
provides an industry-leading Graphics experience as well as a 5 and a/4 in Bay
with easy access inputs for your VR device learn more at the link in the
video description so I think we should open with a primer on what this word
virtualization really means those of you who are intimately familiar with it can
skip ahead because Taran gave me a hard time after we filmed the quadruple your
networking Speed video about not really explaining what I was talking about and
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
video so let's start with an analogy this is a gigabit network interface card
or Nick it's physical because I can hold
it in my hand and it's a network interface card because it connects
whatever it's plugged into into a network and allows those two things to
communicate or interface with each other at a speed of 1 gigabit or about 110
megabytes per second pretty straightforward a virtual Nick is
inherently more abstract while it does
still require some Hardware I mean without a physical cable plugged into
something it can't connect to a device outside of the machine on which it
resides and in most cases it presents
itself to the operating system as though it is a piece of Hardware it's actually
just some clever software pretending to
be Hardware which gives it some cool functionality not the least of which is
that it is able to share its resources
so back to our physical Nick again it's got that gigabit connection speed I
talked about before well by creating two
virtual Nicks we can actually share that
speed between virtual devices like I did
in the gaming Naas video where we had both a file server and a gaming machine
using the same network connection so this is a very flexible solution because
it means that either of these devices can use anywhere from zero all the way
to 100% of the available resources
sharing them dynamically and thanks to some really cool Tech from Intel and AMD
this can even be done on things like CPUs meaning that you can create entire
virtual computers full of virtual devices that share physical Resources
with each other for better overall efficiency cool minus but what was up
with that big asterisk a minute ago well the KVM kernel-based virtual machine
project at red hat which is what unraid is using to power its virtualization is
some pretty freaking impressive software but virtual devices do not have 100% of
the performance of the physical devices because while the days of emulation
that's a very slow way of doing this virtual device stuff are basically over
there is still some overhead involved which thank you for your patience by the
way brings us finally to the topic for today how much of our raw or bare metal
performance are we giving up when we do a project like gaming NZ or seven Gamers
one CPU so for this test I actually
ended up using my personal rig because I had to work on it at home and I left my
test bench at the office but the good news is that with its 5960x Rampage 5
extreme 99 motherboard gtx980ti and 64
gigs of Dominator memory my rig is pretty much the same as my usual test
bench so I started then by establishing
my Baseline performance I ran my test Suite with all eight cores active then I
used the BIOS to turn off one of the
physical cores on the CPU making it effectively a s core this was done
because for the best performance on unraid anyway in games it's best to
leave a core aside for unraid to use and
give everything else to your virtual machine and while gaming actually didn't
end up being affected negatively at all I mean these results are within my
margin of error for these tests this was
expected since games are not very CPU bound these days and the video card
itself is actually passed through as a
physical device to the virtual machine
cinebench also showed the same result results our virtual 7 core and our bare
metal 7 core performed the same leaving
the only test that showed a dramatic difference being the synthetic memory
and cache test in Ida 64 so depending on
the workload it is possible that these extra Nan of additional latency could be
a problem but from looking at performance in consumer oriented
workloads it seems like we are pretty darn close to a VM being a Sol solid
alternative to running straight on the hardware now then it's just got to get a
little bit easier for everyday people to do because while some of the benefits uh
virtualizing servers to consolidate functionality are more applicable to the
data center there is some really cool stuff that I can Envision for a consumer
facing product like unraid as well with
the gaming Naz we did a little while back being just the tip of the iceberg
tunnel bear is the easy to usee VPN app for mobile and desktop it lets you
tunnel so to speak into up to 20
different countries allowing you to browse the internet and use online
services as though you are in a different country so you know let's say
for example you want to access a website that is blocked in your country or you
want to access a service that is just
plain not available in your country due to licensing or whatever else ha screw
that because they've got apps for iOS Android PC and mac and they also have a
Chrome extension they're super easy to use just pick a country press the
friendly looking button and boom your connection gets encrypted which by the
way tunnel bear doesn't actually log any of your activity which is very cool and
your public IP address gets switched so you show up as though you're in a
different country and the best part of tunnel bear is that your first 500
megabytes is absolutely free w and after
that the unlimited plans are very reasonably priced so check it out at the
link in the video description and uh by the way you can save 10% by using that
link that's tunnel bear.com LT so thanks for watching guys if you
