What we're gonna do now is we don't have any virtual machines on here. We've done that in our previous sessions. If you want to go back and see those in action, but we're actually gonna go through a bit on the editing, the virtual hard disks on dhe running a san storage area network. Fact, I'll look at the virtual san manager straightaway.
We'll come back to the disc. So
but Tristan, manager on the right here and make sure you've got your service selected. You can also right click and choose it here. Virtual sound manager on this will pop up. It's fairly simple. I'm not gonna go into huge detail on this because if you're gonna be looking at five channels on virtual five channels for your son,
this is gonna be a bit more than your fundamentals. But it's just so you know where they are.
So if you need to create a new one at the top on the left menu here New Fibre channel, son hit, create and urine. So you've got your flipped. The challenger is ready. It's literally that simple. You choose the name, you add some notes and then you hit okay,
that's his complex as it gets with adding a new fibre channel. So if any of you have done physical fibre channel, so you have to install the network's, stole the mission the sand on the network, and then run the fiber cables onto the into the network itself and those kind of things, you know Oh my God, these delicate fibre cables just plug them in.
This tape is virtual, so you literally just goes on a new virtual fibre channel at it, and that's it. You're done. So that's raising and what you do underneath, you got your global fibre channel settings. These are likely to set your minimum and maximum worldwide port names,
which are basically like addresses they can be. They will be assigned dynamically to a virtual fibre channel port,
but you can set the minimum and the maximum. It's kind of like an address range with I p before or a P B six. Actually, I don't know why I selected before, but you can set, you know. I want to give it an I P address from 1 91 68012121680 10 on it lonely. Use that range and it's the same here.
You can see they're slightly different if you've not used five channels before, I would suggest you go and learn about five tentacles first, before coming to use the virtual machine. Virtual fiber channels on getting bold there, and you can also hear set the worldwide No name as well so that the address for that that could be assigned as well to have five Channel port.
So it's not so simple, really easy to use. I'm gonna click. Cancel it. I don't want to create a new fibre channel, my machine, but that's where you would go to do it. So let's move on to the disc. The final part of honor got Service's After Let's Do the disk first. So we want to make a brand new disk virtual hard disk, which we're gonna use. We're gonna click on new on the hard disk,
and we'll get this pop up here now if you don't use this before you may get the book before you begin screen. So I take the box to say, Do not show this page again, but that just tells you a quick rundown of what you're about to do.
So what format do you want to use for the virtual hard disk? Now you've got three options.
You got the H D, which is the old style. It's not too good if you have things like power failures or any kind of resiliency or consistency. Issues on your network or on your service only supports up to two terabytes in discs. Eyes on. Basically, it's for things like Window seven Windows, Mr
those kind of machines. So you know news of the HD when you're going legacy. Basically, Ph. D. X is very much up and up, and it's the current technology, for it supports up to 64 terabytes of space. In that file. It's resilient to consistency issues that could occur from things like power failures or anything else. That kind of corruption, it's
It can actually do some of its own checks on itself to get it back up and running.
It's not supported in operating systems earlier than Windows eight. So if you're using a on a warm words, you're fine. If you're using seven, it's not gonna work. You need to use a PhD So that's why they still have a PhD in there.
Bhd sets now. This former eventually set is for shared virtual hard disks enables backing up of virtual machine groups using shed virtual hard disks.
You need to have Windows 10 or above, I say above. Because of its future proofing.
You'd have Windows tenor above in order to use of the HD set, but it's used for sharing a virtual hard disk across multiple machines and multiple viens. You wouldn't generally use it if you just want a disk to be accessed by one B. M. But this is that option is available as well. If you wanted to be a TV set,
we're gonna choose V. Hdx because it's the most relevant at the time of this video,
and then from here. What type of virtual hardest do you want to create so you can have fixed size? Fixed size provides usually provides better performance on dhe. If you're running applications with high disc usage, you probably want a fixed size, so it's not constantly re sizing the discus. It goes a lot.
What it does is when you use fixed size, it basically means that
you're going to set the size of the disc is going to take up that size no matter even if it's not using that space. So if you get 100 gig, but your your installation is only 20 it's going to still take up 100 gig off the file off that disk in the V h D on. But it will only take that size. You can
expanded and contracted if you want,
but you need to actually take the disk offline and edit it in order to do that.
Dynamically. Expanding is the more modern one allows better use of physical storage space, and it's recommended for things that aren't so intensive on disk use. Eso What it does is you could you could tell it I want 60 terabytes of space for this disc, but it would only use the amount of space that actually requires that time up to
the maximum that you tell it.
So if you say I want a 200 gig disk, but it's dynamically expanding and then you make that disk, it only be about five men in size until you decide to actually start putting data on that disk. So it's a really nice way to what's called thin provisioning your disks.
If you know that later on, you're gonna be expanding the the amount available to the disk,
you can just set it now and then not worry about it later, but only use it if it's not a disc sensitive or disc disc sensitive. Ah hi disc usage environment like her using a database or an application that always accesses the disc, I would say Use a fixed size on that one
difference ing. This is a type of disk that's associating what we call a parent child relationship, So this would be if you run if you want. I'll give you a real world example. If you're rolling out
virtual machines to everyone to use our network, say your virtualized in your environment on you want the Windows 10 environment, but you don't want everyone to have their own 60 gig orm or Windows 10 V. H. D. What you would do is make 1 60 gig Windows 10 V H. D. Using either dynamically expanding or fixed site.
and you would set it as a difference in this. Now what this means is, is that the disk is read only on, everyone will be able to read it, but any changes they make are stored in tow. A separate small file with their personal preferences and changes. And then you would keep the difference ing disk up to date with patches and stuff. As an administrator,
it means you're not having multiple huge disks on your network. You've got one, and everyone's got their own little personal disk on when they go to read and load their Windows 10 environment, it first loads the main difference ing disc and says, Right, read the disk and load everything in and then it take the checks. And those old this user has
this extra little disconcerting to load on top.
It's kind of like overwriting settings.
That thing gets loaded
on dhe. It makes the appropriate changes. If they've got a blue background on the desktop,
they'll see blue. Someone else might have red, green, whatever. I'm just giving you an example, so it allows you to do that kind of thing. We're gonna choose dynamically expanding for our disk. However you choose the name, so I'm gonna call this dynamic this one.
Whatever you wanna call it, You don't need to have a ll together. You can put spaces in there as well. If you wish.
Choose a location. You can see it's defaulted. To what? I've settled server previously. I'm gonna leave it that you can choose a different area if you want.
