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!
Network traffic is one of those things that are vital for your workflow in all ways. However, the sad truth is that equipment fails, and if you don’t want anything to disrupt the work, you ought to have a backup plan. Find out from this article how to load balance network traffic between the physical NICs on ESXi host.
Every admin knows a few tricks to find a short way when testing your VMs. Some of them are neat, and some aren’t, such as snapshots. Disk Mode in VMware ESXI allows you to replace this technology with a safe alternative!
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!
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.
As the title is speaking for itself, it is quite clear that today, I am going to discuss various methods to open and close firewall ports on ESXi hosts. It is useless to consider whether configuring firewall rules is harmful or not since every admin once in a while meets the necessity of fine-tuning network to distribute access rights. So, you ought to know all the tools at your disposal one way or another.
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 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.
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.
