The best practices covered here will focus largely on management and configuration solutions so should remain relevant for quite some time. As such, this eBook assumes readers already have a basic understanding of vSphere and will cover the best practices for four key aspects of any vSphere environment. I was approached to write this eBook to put that experience to use to help people currently working with vSphere step up their game and reach that next level.
In my extensive career as a VMware consultant and teacher (I’m a VMware Certified Instructor) I have worked with people of all competence levels and been asked hundreds - if not thousands - of questions on vSphere.

Now that the basics have been covered, download the eBook to discover how to put this theory into practice! Long-term solution: Reconfiguration of a virtual machine or host.
Short-term solution: Implement a quick workaround. When and what type of fix should you implement? A short-term one or a long-term solution? Assess the impact of your solution on daily operations. Once you have identified the root cause, you should assess the impact of the problem on your day to day operations. It’s hard to believe sometimes, but you might need another host to help with load! In terms of virtual machine level issues, is it possible that you could have a limit or share value that’s misconfigured? At the ESXi Host Level, you could need additional resources. They get the job done but they utilize a lot of memory doing it. Let’s face it, some of the applications we use are not perfect. Guest OS Level issues typically cause a large amount of problems. You should decide if it’s best to work from a “Top Down” or “Bottom Up” approach to determine the root cause. If you know HOW they should be running, it’s easier to pinpoint a problem. It can be helpful as well to take a benchmark of your systems before they are implemented into a production environment. If you can find a way to reproduce it, you have a great way to validate that the issue is resolved when you do fix it. One of the first things you should try to do when experiencing a problem with a host, is try to reproduce the issue. Define the problem and gather information.

After that, we’ll break this eBook into the following sections: Installation, Virtual Machines, Networking, Storage, vCenter/ESXi and Clustering.ĮSXi and vSphere problems arise from many different places, but they generally fall into one of these categories: Hardware issues, Resource contention, Network attacks, Software bugs, and Configuration problems.Ī typical troubleshooting process contains several tasks: 1. We’ll start with a troubleshooting methodology and how to gather logs. Before we begin, we need to start off with an introduction to a few things that will make life easier. This eBook explains how to identify problems with vSphere and how to solve them.
