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

Upgrading ESXi


Prior to beginning an ESXi upgrade, ensure to read the release notes and back up the host configuration. ESXi can be upgraded in one of several ways:

  • vSphere Update Manager

  • Interactive upgrade using ESXi installer

  • Scripted upgrade

  • vSphere Auto Deploy

  • esxcli

Determine which method is most appropriate for upgrading your infrastructure. This section will cover using vSphere Update Manager.

Importing a Host Image

Before creating an upgrade baseline for ESXi hosts, a host image must first be imported. To import a host image:

  1. Download an ESXi image in .iso format from VMware's website.

  2. Log into the vSphere Web Client and navigate to vSphere Update Manager.

  3. Select the Manage tab and click the ESXi Images button.

  4. Choose the Import ESXi Image button:
