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

vSphere permissions


Single Sign-On provides authentication, but once authenticated vCenter Server defines the scope of access. Permissions are defined within the vCenter Server inventory hierarchy and consist of three things:

  • User/Group: This specifies who has access

  • Role: This specifies the user or group's privileges

  • Object: This specifies where the user or group can execute their privileges

In order to have permissions, all three of these must be defined.

Defining a custom role

There are three built-in roles: administrator, no access, and read-only. Quite a few sample roles have also been created and are available for use. Custom roles may also be created to fit an organization's needs. To create a custom role:

  1. Log into the vSphere Web Client as an administrator.

  2. Navigate to Administration and select Roles under Access Control.

  3. To create a custom role, click on the Add button (+).

  4. The Create Role dialog will appear. Go through and select the desired privileges for the role. The example is called...
