An ability to back up and restore vCenter Server Appliance (vCSA) configurations appeared back in vCSA 6.5. I guess that many have already used it. If you were unlucky to restore from that backup, you know that this procedure is not that straightforward. Bad news: In vCSA 6.7 Update 1 configuration restore process is still like that. In today’s article, I take a closer look at how you back up and restore VMware vCSA 6.7 configuration.
19 September 2018, VMware announced the end General availability for vSphere 5.5 – their probably most installed vSphere versions to date. But, wait, why write about it in January 2019? You see, some being misled by a title starting with “End”, think that it might be the end for the solution… WRONG! To overcome this fallacy, I decided to write an article that sheds light on VMware Lifecycle Policy and proves that End of General Availability is not the end!
Quick Boot is another cool feature introduced in vSphere 6.7. Why does it deserve own article? Because, with this feature in place, rebooting ESXi won’t lead to restarting a server itself. By optimizing the reboot path, Quick Boot enables to avoid time-consuming firmware and device initialization processes. Looks really handy when all you need is just applying small changes or doing some update quickly, doesn’t it? In this article, I discuss how to quick boot a server and share my experience of using that feature. How fast will ESXi reboot with that feature in place?
While writing my previous article, I remembered the days when I was only building my first lab. It was a bit tough, you know, as vSphere yet was a black box for me. Those thoughts brought me to the idea of writing this article. The article in which I share my know-how of building a minimalistic lab using… only a PC, switch, and laptop. I’ve divided this topic into 2 parts as I am unsure whether you guys like long-reads. In this part, I discuss how to build an ESXi environment using PC and ESXi 6.7 U1. The next article addresses creating a lab using PC and VMware Workstation 15 Pro. I hope that both of them will be really handy for you!
VMware Tools is a handy utility suite that makes your VMs run faster and dramatically simplifies their management on the whole. And, the nice thing is, it installs fairly easy on your VMware VMs regardless of their guest OS. Today, I’m going to talk about VMware Tools in general and how to install the package in different environments.
Sometimes, you badly need to provide your VMware VMs with more RAM or vCPUs without shutting them down. True, there’s a trick allowing you to do that – CPU Hot-Plug and Memory Hot-Add. In this article, I’ll discuss both these features and how to use them in different environments.
If you are new to VMware or just starting out in the tech, you may feel a bit confused about products naming. Well, at least I was. There are tons of products in the suite so many have a hard time grasping how all those things come together. For instance, it may be hard for a beginner to tell apart ESXi and vSphere. What should you do? Well, nothing special, you know. Google. Ask fellow admins. Look through forums. Read books. Well, my post is not here to bring you from the very beginning to finish.
Passwords are the things people tend to forget. Well, ESXi root passwords are not an exception either! Without the root password, you lose control over your hosts, so it’s good to know how to reset it. Well, resetting an ESXi host password is the thing I gonna talk about in this article.
Deduplication is a cool technique that some admins use when it comes to saving storage space. No wonder. By deduping, you can gain some extra storage even without deleting anything. Everyone seems to use it, but how does that thing, actually, work? In this article, I’ll look under dedupe hood to understand better its operating principles. Why one may need this? You see, you always can make the most of things once you understand how they work. I believe this principle to apply to almost everything! So, here’s why I examine such a common storage optimization technique as deduplication in this article.
Sometimes, you badly need your ESXi VM data, but that thing just cannot be powered on for some reason! Well, you can try starting that VM one more time according to this article and access the data with a little luck. But, if you are out of luck and the VM is dead, you need another method to extract its VMDK file content.
