Overview of this book

Computer virtualization is a method to enable the running of multiple application workloads on a machine to achieve efficient utilization and reduce the number of physical machines in a data center. This has now become the foundation of many modern day data centers. What began as a technology to virtualize x86 architecture has now grown beyond the limits of a server’s hardware and into the realm of storage and network virtualization. VMware is currently the market leader in developing data center virtualization solutions. This book goes into the details of designing and implementing VMware solutions that form the foundation of a VMware infrastructure. The book begins by introducing you to the concepts of server virtualization followed by the architecture of VMware’s hypervisor – ESXi and then by its installation and configuration. You then learn what is required to manage a vSphere environment and configure advanced management capabilities of vCenter. Next you are taken through topics on vSphere Networking, Storage, ESXi Clustering, Resource Management and Virtual Machine Management. You will then be introduced to SSL Certificate Management and its use in a vSphere environment. Finally, you will learn about the lifecycle management of a vSphere environment by effectively monitoring, patching and upgrading vSphere components using Update Manager. By the end of the book, you will know how to use VMware’s vSphere suite of components to lay the foundation of a modern day virtual infrastructure.

Preface

Host profiles


Host profiles are a vSphere Enterprise Plus feature that can greatly simplify the host configuration management required as your deployment scales out, by using configuration policies. Host profile policies can be used to eliminate per-host manual configuration, and to maintain configuration consistency across the entire datacenter. Host profiles are essentially blueprints or templates of known, validated gold ESXi configurations. These can be used to manage settings and monitor compliance for networking, storage, security, and other configurations for multiple ESXi hosts. Host profiles can be managed using the vSphere Web Client, PowerCLI, or vSphere APIs.

Overview of host profile workflow

The workflow for host profiles starts with the reference host. A reference host acts as the template from which the host profile is referenced and created. The process would go as follows:

  1. Install ESXi and configure the reference host.

  2. Create a host profile from reference host.

  3. Modify host profile...
