So with that in mind, let's come to the end of that section will go through a few more questions. Just something to get your brain ticking over again. What two situations would you not use?
so we did discuss a little bit about, um,
where whether you're running the ends that need something specific or like the environment, they might be in S O. We did discuss it a little bit earlier. The 1st 1 is when a virtual machine is a priority. If you have a machine that you know if if the strategy of your business or whatever is that you need this machine
always always, always
that set amount of ramen because it does a constant work at a constant rate you would set he turned down on that memory often go just give that machine 12 Gig of ram or whatever it might be
she just wouldn't use. You wouldn't use dynamic memory, that environment. The other option is when there is more memory available than virtual machines they're using when they're all at full capacity. You don't need dynamic memory at that point. Instead, what you should be doing is setting the machines to use static memory and just give them the full amount that they need.
The pope. Then you wouldn't have changes and fluctuations in performance, which you can get a little bit with. Dynamic memory. It's just good resource usage.
Double. There's really no need to rolling around with dynamic memory. Anyway,
Andi wouldn't need smart paging files because of that as well. So
right, Question two. What is a memory buffer?
This is the sliding scale.
Yes, sir. Just go. Absolutely. If you have too much memory, totally on point. So what is a memory buffer
If you guys wanna have a go on it? What? This is that sliding scale one. What does it do? Give me a rundown. And, Jessica, if you feel up to it, jump in with the answer for this one as well, buddy. Absolutely. Show me what you've got. So what is it? It's that sliding scale with the low and high end on it. What does it do? How does it work?
Give me a few seconds more to kind of come up with it,
yeah, throw it at me.
our hold too long. I don't wanna waste everyone's time. You're probably all just shouting at the screen. I would love for you guys to engage more. I absolutely would. But I know some people are a little shy. It's no problem. It takes a certain certain personality do. This kind of stuff
is the percentage of memory that hyper V should allocate to the V M as a buffer
s. So that's basically it s o. If I'm using 600 Meg, it will give me 750 if I'm using 750 or give me 900 so on and so forth. It allows me that extra bit of gap, so I'm not totally squeezing in tow.
When is the only time smart paging is used? The only time there is no other reason to use smart paging. Apart from this one,
though there is those zero. It will never actually engage
unless this situation occurs.
when the machine restarts.
And only then, Yes, Sandy. Absolutely, absolutely, yes. Brilliant. Well done. So it's only when a machine restarts and only then it's only when there is no available memory for it.
So it's not going to kick in if you If the machine needs a gig to load and there's eight weeks spare, smart paging isn't gonna do anything. If the machine has eight big toe load in this four gig spare, you're gonna get four gig smart paging file as well.
So that's all it's referring to.
All right. Good work, guys. Okay, so learning objectives. Hey, what did we cover? We created an understanding of what dynamic memory is on how to configure it
on. We did an understanding of what smart paging is and how to configure it. Now
what I'd like to do. So, Eric, you say we start most is cold. Start up so
will only kick in on a restart if the machine is off and you tell the machine to turn on. But there's not enough ram available.
Smart paging will not help you, my friend.
Smart paging only works on a restart is ultra specific.
I don't know why Microsoft have made it that way.
It must be something to do with the security of the way and machine boots because there's not the same checks when you restart machine is toe When you when you called boot the machine itself. But cold startup needs the physical ram available. A restart doesn't it can use a smart paging file,
so yeah, keep that in mind.
So I know we've done just about an hour now, guys, and I know this is about an hour and 1/2 long.
I know there is a Q and A section in this, but I'm so glad you guys are engaging with me at the moment in chat on, like you and A along the way effectively. So what I'm gonna do instead is we're gonna cover another module. It's not too big a module. It's just covering software infrastructure in general because what I want to do is I want to put us in a position where next week
we're going to build
a network Onda virtual machine from scratch, hook them together and get them online, get them working.
It's gonna really excited for it, cause then you guys get to see what we've discussed so far in action, and then you guys can actually do it as well because I'm doing it. I'm not doing it on a big, powerful server anything. I'm doing it on a Windows 10 machine.
If I do it on my screen, you can then maybe play the video back. Play to run, or you can try it with me A while you get Get the machine ready up and running so you could get hyper V installed on. We will cover installing my pervious. Well, so if you want to do that as well, bear in mind. If you do want to follow along,
you will need hyper V priest or because there is a reboot that's installed. But I will show you the commands for that.
