Learn about the Configuration Maximums document for vSphere 6.5, which emphasizes the changes from 6.0 to 6.5.
- [Instructor] One of the things that VMware is very faithful about doing is releasing a new Configuration Maximums document with each new version of vSphere, and vSphere 6.5 is no exception. The easiest way to find it, of course, is just Google it. So I'm just going to put in vSphere 6.5 and start to type in configuration maximums. I don't even have to type it all in, and it'll fill it in for me. Press Enter, and then what I want is the PDF.
So I'm going to click on Configuration Maximums. And of course, if you have Adobe Acrobat Reader or Adobe Acrobat, then it'll come up. And the Configuration Maximums document is a complete document that tells you the new configuration maximums for all of the different components in vSphere. Now I'm just scrolling down here to the Contents, and you can see that it includes the host. It includes vCenter, the Platform Services Controller. Many of these things, we're going to talk about in more detail later on.
And I'm going to keep on scrolling down here and come down to where we have all of these hyperlinks. So if I wanted to quickly find out about the new configuration maximums, for example, virtual machines, then I could just click on the hyperlink for virtual machines. Now, we're going to talk about the virtual machine maximums when we talk about the new Virtual Hardware version 13, which is going to be later on, but right now what I want to focus on are the ESXi host maximums and the vCenter maximums.
But as you can see, you can look up any of them very quickly. So if I click on ESXi Host Maximums, then you'll see that we have hyperlinks for compute, for memory, for storage, networking maximums. So, for example, if I were to scroll down through here, as you can see, the compute maximums are way up from previous versions. If you're not familiar with the previous versions, we couldn't have 576 logical CPUs per host.
Take a look at the previous versions for 5.5, for 5.1, it was much less than that. So it's been going up exponentially over time. The memory maximums, we're up to 12 terabytes. I remember when the total terabytes on each host was one. Then it was two, then it was four, now it's 12 for 6.5. Now, do you really need 12 terabytes on a single host? Probably not. But if you did, you could. And these things are good to know for the test, but they're also good to know just for real life.
If you're going to be considered an expert in your field, then you need to know what the capability of a system is, how far could I push it. Storage maximums are up from what they were. It used to be that we could only represent 256 LUNs, and they were zero through 255. Now the LUNs per server is up to 512. So I'm just pointing out some of these just as we go along, and we'll talk about some of the configuration maximums and what their impact is or what their impact could be to you with the new technologies as well.
Now I'm going to scroll down to Networking Maximums. And as you can see here, they start to get into the different brands of network card and the fact that there's a different maximum there. When they get that specific, that, you can pretty well rely on, is not going to be on the test, but it could be very useful for real life if you have that type of card. In other words, vendor-specific information, in my experience, is not really testable information.
However, it could still be very useful information. We come down here, and we look at the number of port groups that you can have per distributed switch. That's still 10,000. 10,000 seems like a lot of port groups, right, a lot of broadcast domains. But as we start to get into software-defined networks, such as NSX, I'll bet what you're going to see is that is going to increase over time as well. Right now it's 10,000 port groups. So I'm just looking at some of these examples.
And like I said, later we will talk about these in more detail and what impact that might have on you. Main thing is, wanted you to know where to find it, and maybe you didn't even know that there was a document that is this complete that you can easily find information on. One of the ones that has really increased is the capability of the vCenter itself. The vCenter Server, whereas it used to support up to 10,000 powered-on virtual machines, 15,000 registered virtual machines, as you can see, now it supports 25,000 powered-on virtual machines, 2 1/2 times as many, and registered virtual machines, 35,000.
So these have increased tremendously over time. So as you can see, it's easy to find out what the system is capable of by looking at the Configuration Maximums document, but some of these maximums may have more impact on you than others. And one of the aspects that may have a lot of impact on you would be what kind of virtual machines that you can build. So we're going to take a look at your new virtual maximums now.
