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 vCenter Server


Keep in mind that the vCenter Server architecture has changed in vSphere 6. Refer back to Chapter 3, The Management Layer - VMware vCenter for more information.

Upgrade Paths

An infrastructure's vCenter Server 5.1/5.5 configuration will determine its configuration post-upgrade. If the outcome is not desired, consider installing a new vCenter Server rather than completing an in-place upgrade. However, if the vCenter Server is 5.0, there is no Single Sign-On installed and configured, therefore an option will be presented to choose whether the vCenter Server 6.0 configuration should be embedded or external.

The following image demonstrates a vCenter Server 5.1 or 5.5 simple installation, where all components were installed on the same system. When upgrading to vCenter Server 6.0, the outcome will result in an embedded configuration (with the vCenter Server and Platform Service Controller components co-installed on the same system).

On the other hand, if the vCenter Server...
