Recently, I decided to automate some boring routine procedures related to setting up virtual networks in ESXi 6.5. That’s right, I’m talking about PowerCLI. This command-line tools allows automating all aspects of vSphere management, including network, storage, VM and so on and so forth. Sure, I had to dig into the details of orchestrating ESXi with PowerCLI. Yep, it took me some time but at the end of the day, the knowledge and experience I acquired paid back! Apparently, this case is not unique, so I decided to share my experience in today’s scribbling.

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.

Discover how this technology helps organizations make better use of their hardware resources, and dive into the principles of virtualization technology, its benefits, types, and use cases.

Leakage of confidential business information can become a true disaster for any company. Therefore, data security is an issue of prime importance for most of companies. Organizing an IT infrastructure, administrators’ top question is how to warrant a secure storage to keep sensitive business information. In this article, I suggest having a closer look at a relatively recent method of ensuring data security – VMware virtual machines encryption that can become a good remedy against intruders for your organization.

Some time ago, I published articles on setting up a home lab using a PC running ESXi and Workstation. We all know that nested virtualization is not an ESXi-only feature; Microsoft Hyper-V also enables us to run VMs inside its VMs. Microsoft’s implementation of this technology is a bit different, but it exists. And, considering that VMware and Microsoft have been competing for a long time, it’s interesting to see what each has to offer for this type of virtualization. In this post, I examine how easy it is to configure a nested virtualization layer inside Hyper-V and vSphere VMs and discuss peculiarities of this process in both environments.

As an admin, I often have to deal with the necessity to transfer large OVF and ISO files or even move virtual machines (VMs) between ESXi hosts that have poor network performance or disposed in different locations with no network connection whatsoever. If a case like this occurs, a USB flash drive or USB external drive is a way to go. More specifically, you can use a drive in two different ways (by the way, both authors have my most sincere regards and appreciation for presenting these methods in a most coherent and simultaneously simple way). The first one is to copy files from a USB device to a host directly through SSH session without changing drive format as the following article suggests. However, such an approach has some issues, the most tedious one being maximum file size limitations, which certainly limits its use for larger files. You cannot work with the Graphical user interface (GUI) as well. Instead, you gotta use SSH and dive deep into the host data storage system, so you can figure I am a much bigger fan of a second way: creating a VMFS datastore on a USB drive. You can connect it to ESXi hosts and transfer files from one to another (or just store a temporary copy on an external storage device).

ESXi root password lost? No worries! Our latest article unveils 4 effective strategies to reset it, ensuring you maintain access and control over your infrastructure. Whether you’re accessing via vCenter or dealing with standalone hosts, we’ve simplified the process for you.

As the name of this article is hinting, I’m going to discuss the answers to the said questions. My beginner colleagues are often wondering what virtual disk is preferable to choose. Therefore, although I was talking about this topic a while ago here and there, it’s time to get to the point.

There are always several reasons to move on from your existing infrastructure. Some admins are pursuing recent versions of familiar products. Some, on the other hand, just want to get rid of the bugs they already learned to live with but would rather not. Others are attracted by promises to increase the performance of their environment. Finally, everybody wishes to go with the times and use the latest software. Whatever the reason, we all eventually come in terms with the necessity to upgrade the infrastructure to the most recent version.
