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.
In this post, I’d like to discuss data consistency – an important thing when it comes to backups. If data is consistent, it can be used across your environment, so you can spin up applications faster after restoring from such backup. Actually, it’s why I think this topic to be so important even now.
This post will be pretty handy for those who rely on their memory too much because it discusses how to reset vCenter Server Appliance root password.
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.
Admins shut down their hosts for servicing from time to time. After closing for maintenance one node, vSAN cluster resources are to be re-distributed, and here Maintenance Mode comes into play. Today, I’d like to discuss the whole idea of maintenance mode and its options.
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.
Hi, guys, I finally managed to finish an article on deploying VMware vSAN on the nested ESXi hosts. Some had difficulties with setting up the networking for this scenario, so here’s a guide on this matter from me!
Today, I’d like to share some of cool ESXCLI commands for performing a good part of IT related routines. Sure, vSphere Client has a wonderful GUI allowing for carrying out most of daily tasks… but CLI is much more powerful tool once you master it! So, that’s actually why I share my “Swiss Army knife” commands here.
