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

Auto Deploy


vSphere Auto Deploy is a cool feature that came out with vSphere 5. It allows you the ability to provision hundreds of ESXi hosts at a time. You specify the image to deploy, which hosts to provision, a host profile for the settings, a target vCenter Server, and cluster, and voila, you'll have your ESXi host provisioned in no time! Once Auto Deploy is configured, the ESXi hosts will use a PXE boot infrastructure paired with host profiles to provision and customize the hosts. This can be configured for stateless, stateless caching, or stateful.

Let's take a look at the three types of Auto Deploy setup:

  • Stateless - the image resides in the memory; no local disks needed. PXE infrastructure will always be used for boot.

  • Stateless caching - introduced in vSphere 5.1, this feature allows you to cache the ESXi host's image locally on a host disk or a USB device. The ESXi host will continue to boot using the PXE infrastructure unless its unavailable, at which point it would boot from the...
