Overview of this book

VMware vSphere is the most comprehensive core suite of SDDC solutions on the market. It helps transform data centers into simplified on-premises private cloud infrastructures. This edition of the book focuses on the latest version, vSphere 6.7. The books starts with chapters covering the greenfield deployment of vSphere 6.7 components and the upgrade of existing vSphere components to 6.7. You will then learn how to configure storage and network access for a vSphere environment. Get to grips with optimizing your vSphere environment for resource distribution and utilization using features such as DRS and DPM, along with enabling high availability for vSphere components using vSphere HA, VMware FT, and VCHA. Then, you will learn how to facilitate large-scale deployment of stateless/stateful ESXi hosts using Auto Deploy. Finally, you will explore how to upgrade/patch a vSphere environment using vSphere Update Manager, secure it using SSL certificates, and then monitor its performance with tools such as vSphere Performance Charts and esxtop. By the end of this book, you'll be well versed in the core functionalities of vSphere 6.7 and be able to effectively deploy, manage, secure, and monitor your environment.

Enabling vSphere High Availability

vSphere HA can only be enabled via the vCenter Server that is managing the ESXi cluster. Since HA restarts virtual machines that were running on a failed host, it is essential to ensure that all of the ESXi hosts in the cluster have access to the same storage and the same virtual machine networks and that they have CPUs from the same family and feature set. If these factors are not considered before enabling HA on a cluster, then it could increase the chances of unplanned downtime.

In this recipe, we will learn how to enable HA on a host cluster.

How to do it...

The following procedure will help you to enable and configure HA on an ESXi cluster:
