In this video, Russ Long tours the lab envioronment he will use for this course. Explore his base configuration, including two physical server, and the high availabilty cluster he will configure.
- [Instructor] Now before we get started, I want to give you a small tour of the lab we are working in. First, we will be logging in using the IP address of our vCenter server. At the top of the browser here you can see I've already entered the address. We can see we're already at the log in page. So, let's go ahead and log in. I'm going to click Login here. And as that's logging in, I want you to note that at the beginning of 5.5 and later on, ESX requires the use of the UPN format or user principal name.
This is the user name and the @ symbol with a domain. Now, that doesn't have to be an active domain, it can just be a domain that you make up. But, that is the new log in format. Now, what I'm going to do know, is I'm going to click on Hosts and Clusters here. We really want to dive into what makes up this lab. Now, if you look on the left hand side, you can see that we have the HA cluster and the infrastructure cluster. First, we're going to focus on the infrastructure. So, I'm going to go ahead and close the HA cluster for now, and let's focus on the infrastructure cluster.
Now, these are my true physical servers. 202 and 203 are both real physical servers in my environment. You can see under them that the VMs are what make up my shared storage, my host that will act as our HA cluster. This is what's known as a nested environment. I have hosts that are actually virtual machines on other hosts. Although, this is great for a lab environment, do not do this in production.
That's a bad idea. So, now that we know what makes up the physical part of my cluster, let's take a look at the HA cluster. I'm going to close our infrastructure cluster, and I'm going to expand out the HA cluster. Now, as you can see, this is made up of two hosts and four virtual machines. This is all virtualized hardware. This allows us flexibility in our lab environment. Here we can enable HA or any other technology we wish without effecting the physical infrastructure.
