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.

Performing Host Customizations

vSphere Host Profiles can be used to maintain a standard configuration across clusters of ESXi hosts. However, every host will have a set of unique settings—for instance, the IP addresses of the VMkernel interfaces. You can modify such unique settings by launching the Edit Host Customizations wizard for each object (cluster/host). However, it is understandably an error-prone and cumbersome process to edit the setting of each host using the wizard interface.

An alternative and efficient method would be to prepare a customizations (.csv) file with the host-specific values and use it to perform the host customization.

In this recipe, we will learn how to export and prepare a customization file and then use it for remediating customizations to the attached objects.

The following diagram depicts a high-level overview of this process:
