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.

Setting a migration threshold

Once DRS is enabled, several algorithms and metrics are continually evaluated to ascertain the optimal VM placement. However, the user may need to set the appropriate threshold to balance how aggressively or conservatively DRS should migrate VMs. This will ensure that, based on the criticality of the workload, it can be migrated when required. Another rationale behind this setting is to ensure that there is no negative impact, such as a frequent ping-pong of VMs across hosts.

How to do it...

In this recipe, we shall increase the threshold value to migrate VMs if there could be moderate improvements made to the cluster's load balance:

  1. Log in to vCenter and navigate to the desired cluster...
