Overview of this book

VMware vSphere is a complete and robust virtualization product suite that helps transform data centers into simplified on-premises cloud infrastructures, providing for the automation and orchestration of workload deployment and life cycle management of the infrastructure. This book focuses on the latest release of VMware vSphere and follows a recipe-based approach, giving you hands-on instructions required to deploy and manage a vSphere environment. The book starts with the procedures involved in upgrading your existing vSphere infrastructure to vSphere 6.5, followed by deploying a new vSphere 6.5 environment. Then the book delves further into the procedures involved in managing storage and network access to the ESXi hosts and the virtual machines running on them. Moving on, the book covers high availability and fair distribution/utilization of clustered compute and storage resources. Finally, the book covers patching and upgrading the vSphere infrastructure using VUM, certificate management using VMCA, and finishes with a chapter covering the tools that can be used to monitor the performance of a vSphere infrastructure.

Enabling vSphere HA on a cluster

The fundamental principle of HA is to be able to recover virtual machines from a host that has failed to another. That implies that other hosts in the cluster are capable of providing compute, storage, and network identity for the virtual machine similar to the failed host.

vSphere HA is not enabled by default on a host cluster. It has to be manually enabled. In this recipe, we will understand the requirements of a HA cluster, how it is enabled, and how it works.

Getting ready

Although the actual process of enabling HA is as simple as a click of the checkbox, in order to successfully host the VMs from a failed host, the following prerequisites need to be met:

  1. All hosts must be licensed for...
