If you have worked with the virtualized infrastructure for a while now, you probably know too well that VMs inevitably start to have performance issues. Luckily for those who use VMware vSphere, there’s a chance to find out more to fix such problems or even prevent them!

Upgrading VCSA 6.5 to 6.7u2

The perfect infrastructure could never exist, but our goal is to move towards one. Learn from the comprehensive guide about upgrading VCSA (VMware vCenter Server Appliance) 6.5 to 6.7u2, and explore a lot of new benefits it offers!

How VMware has covered performance gap between physical and virtual GPUs

Once engineers came up with the way to virtualize graphics processing units (GPUs), the new era started for machine learning, gaming, modeling, and whatever else IOPS-hungry: all these applications can now go cloud! In this article, I’d like to take a closer look at why GPU virtualization is so promising, who pioneers this tech, and how VMware managed to cover the gap between the virtual and bare-metal GPUs.

VMware vSphere Content Libraries in a Nutshell: Why use Them (or Why Not)

Some time ago, discussing how cool VMware vSphere 6.7 Update 1 is, I briefly mentioned content libraries. That article was just an overview, so I decided not to go into details, saying that some features need their own posts. In today’s article, I’d like to share my hands-on experience with content libraries and help you to decide whether this feature can make your life any easier.

How to shrink VMDK with a couple of PowerShell scripts?

While extending a VMDK file is a fairly easy task that can be performed right in Disk Manager, shrinking a virtual disk is a bit tricky. And, you need to be really careful because unless done properly, reducing virtual disk size may cause data loss! Sure, you can just use VMware Converter to make a VMDK smaller, but, for my money, it is always better to have a script at hand. In this article, I’ll discuss how to shrink virtual disks with 2 simple PowerShell scripts.

How to backup & restore with VMware vCSA 6.7

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.

VMware solution lifecycle. Does the End of General Availability mean the end for a solution itself?

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!

ESXi 6.7 Quick Boot in a nutshell. How fast can you actually reboot ESXi?

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?
