If you are referring to this book for starting your first server virtualization and consolidation project, then this section of the book is the important one for the success of your project. Good planning involves taking all infrastructure portions into consideration and ensuring that all project teams have carefully assessed them.

From a real-world standpoint, I have seen many organizations failing to get most out of their virtualization infrastructure because of poor planning at the early stages of their virtualization project. A sound planning process for a virtualization project not only involves sizing and designing your hypervisor server operating system or hardware, but also involves assessing the required infrastructure, for example, storage, server hardware, hypervisor selection, and many more.
