5 hours 8 minutes
you see here, This is the screen that you would see, eh? So you can see here you've got the startup room at the top
just on this environment here. What that does is that allows the machine to claim that amount of memory when you turn it on the initial. I'm gonna give you this amount when you turn it on.
Uh, so that's the way it can be the same as the minimum ram. Or it can be more
anywhere up to the maximum ram. So if you look under here with dynamic memory, you've got your minimum and your maximum now maximum, that sets itself. That's the default. Well, I think it's a terrible year comes out to effectively, but the
the minimum ram is the level of memory that that VM will not drop below.
That's the key thing with this.
So at no point will it say I want less than 512 megabytes of ram,
the maximum which many people usually set to either the size of the memory on the server or soy
this evening the size of a ll the memory
across all of their servers. If they're sharing the ram
then it just says, Look, don't ask for more than this.
And then the memory buffer underneath there is where it goes. Okay, if you've got 500 megabytes of memory or let's say gig a gig of memory,
this is gonna give you 1.2 gigs of memory and saying, right, I'm just gonna give you that extra point to gig
because I wanna make sure that if you have an application that very quickly needs to expand into memory, you're not left hanging, which could feasibly crash the application or create performance issues for the user while they're doing work on that server. So it says, I'm just gonna give you If you're using a gig, I'll give you 1.2 gig. If you're using
half a gig,
I'll give you, uh, refusing 500 make. I'm gonna give you like another. Whatever is 600 Meg. I never, you know, put you up to 600. So you've got that little kind of buffer, and you can set that buffet or whatever you need. Generally, though, the default is 20% on DDE.
I've never been in a situation where I've got a new different
because they generally are very good settings. Toa kind of work with in general
memory white Underneath
the setting you can see on that screen there is actually the default. It's basically neutral. What this does is it allows you to prioritize the availability of the memory that you have as a pool for the specific VM that you're setting it for. So you could say if this VM is a domain controller, I want it to have
more access to memory than another machine, which might be
our preet server, because if the domain goes down, we have a problem. If the print server goes down,
it just has to wait for memory to be allocated to it. The president might slow down a little bit, but it won't stop the network from working effectively. So it's just those kinds of things now
that's basically what you would be setting on a memory. Wait. Generally, most people, unless you have a huge network like multiple level enterprise network, you don't really mess with the memory way unless you have a server that absolutely must be prioritized about everything else.
Maybe a file server said that all the files are always available to people,
that kind of thing. You would push up. You wouldn't generally go below middle unless you like. I don't really care if that server is a problem or more effectively.
so that's the memory buffer in the memory. Wait, keep in mind that memory adjustment is fast, but it is conservative. Thinks what this means is that a virtual ization host
doesn't provide a LL. The resource is at once, even if it could do it right away. So if if the if the virtual machine says I want another four Gig of Ram and it's on four gig already
the host, though, the hyper visor will go. Here's a gig.
Tell me when you get close to the edge of the gig and then I'll give you the rest of what you're asking for it all the next stage of what you're asking for. It won't just go, okay? His four gig and throw it at you unless you specifically set it here is a minimum ram level.
It tries to keep things according to the actual ram consumption in the memory buffer settings. It doesn't just
give in to the guest virtual machine effectively. That's just something to keep in mind in the farm.
So I'm gonna move that off to the side and you want to see here. So this allows you to see what it would look like when the machine is running, so you can see you can't disable dynamic memory or turn it on, even if it's turned off while the machine is running on. But the top, the startup RAM, is also set on grayed out.
The machine has to be off to either
enabled disabled dynamic memory or to change the startup around.
So the startup Graham is just what it starts with. If that start up crime is higher than the minimum, there's a chance that the machine will actually drop down on dhe, dropped down to the minimum level or as much as low as it needs effectively to keep running properly. So you don't have to set the minimum round in the start up around to the same amount,
unless you particularly wanted effectively
