Educational Episodes: Hyperconverged Infrastructure (HCI)

Last year, my colleague asked me for advice. He couldn’t add an iSCSI target, provided by AWS Storage Gateway, on VMware ESXi cluster. So, initially, this material was intended to serve as a manual. However, since I got a similar question once more just recently, I realized that this topic could be interesting to the others as well, which is why I decided to share this guide, hoping it will be useful.

As any other admin, you know that the VMs eventually start to suffer from disruptions, performance problems, or simply stop responding. That is a fact of life, unfortunately. Chances are, as a virtualization engineer, you’ve probably already met these problems at least once. And since the virtualized environment is quite a complicated system, there can be too many different reasons or factors that impact poor VM performance. Trying to find out what is wrong can take a lot of your time.

Test how both hypervisors handle nested virtualization. Great insights if you’re building labs or training environments.

A solid IT infrastructure isn’t just about speed, it’s about cost efficiency. Secondary Storage plays a crucial role in maintaining this balance. Discover what is secondary storage, its use cases, and operating principles.

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.

Proxmox vs. Hyper-V: what’s right for you? Both are powerful virtualization platforms, but the best choice depends on your requirements. See how they differ in management, cost, and ecosystem integration. 

Tune your live migration settings in Hyper-V for faster, smoother VM moves — especially in clustered setups.

Upgrading to Windows Server2025? The big question is whether to go for an in-place upgrade or a clean install. We’ve compared both approaches, highlighting their pros, cons, and best practices in our latest detailed guide. 

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.
