The virtualized datacenter is here. Consider the design options that enable you to transform some or most of your physical servers into virtual machines. You'll get ideas for energy and space-saving options in your organization as you explore provisioning host hardware, virtual networking and storage, and ensuring that your virtual infrastructure is kept patched as thoroughly as a physical infrastructure would be. You'll also explore the exciting area of client virtualization with Microsoft's Virtual Desktop Infrastructure technology!
Course Introduction Hi and welcome to TrainSignal. I'm Mike Hammond and I'm going to be your tour guide through Windows Server 2012 implementing advanced server infrastructure. We're going to be focusing here on virtualization topics, the topics that will allow to develop your expertise in the use of Hyper-V, virtual machines, and all the other supporting technologies that will help support your use of virtual infrastructure. We'll look at strategies to design the administration of that environment. We'll explore the behaviors of the Hyper-V Hosts themselves, how to optimize the use of the hardware that you have available to you. We'll get a variety of techniques for managing the virtual machines themselves, making them a highly-available resource. We'll look at being able to insure that they have appropriate access to virtual networking that we can configure the storage that they live in appropriately. We'll look at ways to deploy them rapidly using System Center Virtual Machine Manager template technology. We'll look at ways we'll be able to patch those virtual machines and the hosts that they reside upon and we'll even explore the recent developments in virtual desktop infrastructure technology. During our time together, you'll see me demonstrate equipment from a fictional company called Globomantics Corporation. They're a fine company. They do a great job with what they do. They do the same thing that your business does. It's just that you do it better than they do. They don't take it personally. You know they appreciate that you guys are a stronger competitor. So enjoy watching Globomantics go through the effort of trying to get their virtualization environment off the ground, and with any luck, that'll help you do the same. So I look forward to moving forward with you. I hope you enjoy implementing an advanced server infrastructure.
Planning for Virtualization Host Resource Optimization Welcome to TrainSignal. We're continuing our discussion of advanced services infrastructure with a discussion of the resources available at our virtual machine hosts. Virtualization is a transformative technology dramatically reshaping the IT landscape. We're able to take large quantities of server resources and condense them down to a smaller set. We're able to dramatically improve the efficiency of usage of our IT resources. It's a good thing. Part of what drives that is our ability to stack multiple virtual machines on the same computer, so that they're sharing the resources of that machine when one server's busy, perhaps that compensated for by the fact that another one is relatively idle at that moment. When that one virtual machine that had been idle suddenly gets busy, well maybe there's another one that's not quite so busy and it all balances out. But what if all the virtual machines on one particular host all get busy at about the same time? They're all demanding all the various resources that virtual machines need.
Designing for Virtualization Networking Hi and welcome to TrainSignal. We're continuing our discussion of networking technologies as we explore the advanced features necessary for supporting a modern IT data center. Virtualization, as we have identified, is a game-changing technology radically reshaping the way that IT organizations run their shops. This lesson focuses specifically on the networking design ideas that we need. How do I make sure that the network environment for my virtualization environment is working the way that I want it to? How do I map the business needs of my organization onto the physical topology that I've got, or that I will build out, in order to support all the business needs that I plan on developing within my virtualization space?
Designing for Virtualization Storage Hi, welcome to TrainSignal. We're continuing our course in advanced services design. Why do I lay out the network in the way that I do? Why do I lay out my storage in the way that I do? Why do I arrange the resources at my disposal as an IT organization? And, how do I arrange all those resources in a way to be able to satisfy the business requirements of the organization that I support? That's our overall goal. We spent quite some time talking about virtualization. And, here we're turning our attention to the storage that underlies it. Storage is significant, if for no other reason than the fact that it's expensive. Many IT organizations will spend as much as 50% of their IT budget spend on storage purchase. Now, it's a dramatic impact on the bottom line. Being able to use it wisely is paramount. Because probably few things bother the boss quite as much as the IT guy walking up and saying, "Hey, Boss, I need another great big, fat check for another big lump of storage. " One obvious question is: Well, are we using our existing storage as efficiently as possible? Because you're sucking up a lot of otherwise useful profit here to be able to build out more storage. We say, "Well, yeah, Boss. All of our employees say that they're using it for perfectly legitimate business reasons. " And, that may be true. But, an interesting question is: Are we as IT provisioning storage to our servers in ways that are efficient in using that storage wisely and well?
Planning VM Infrastructure Maintenance Hi and welcome to TrainSignal. As we move forward, we're going to look at planning infrastructure maintenance underneath your virtual machines. Virtual machines need their own patching regime, of course, but they're sitting on top of a host infrastructure that also needs patching. Those Hyper-V hosts are computers. They are running Windows operating systems. They will need patches as well. But, they've got a logistical problem to deal with. They've got virtual machines resting on top of them. How do we make sure that we're able to adequately patch those computers? There was a time where it was up to somebody to manually select a host to go through patching. That person then needed to manually make a note of what resources were on that failover cluster node. That person then needed to move those resources off of that node that then freed that computer up to be able to receive its Windows Update patches and take its reboot and such. And then, of course, it was time to go patch some other host server. Well, that meant that the resources on that computer needed to come off. Some of those could go onto the computer that was just done being patched, but it also needed to take back some of the resources that it had given up earlier. So, there was a manual process of trying to get everything moved from one server to another, to another, to another to make sure there was enough capability on each server to handle the responsibilities of all those various different resources. And, it was a long, complicated, time-consuming process.
Designing Virtual Machine Updating Infrastructure Hi and welcome to TrainSignal. Continuing the Windows Server 2012 "Implementing an Advanced Server Infrastructure" course. And, our focus here shifts to updating virtual machines in a Server 2012 environment. If I've got a lot of virtual machines in my Server 2012 environment, one of the important challenges I need to manage is how am I going to keep them updated, patched, make sure that their security updates are made, things of that sort.
