Mware Infrastructure 3 (VI3) is a robust, feature-rich, fault-tolerant,
and highly reliable platform for virtualization. In fact, VMware created
x86-based virtualization. (Now that I got that out of my system, it’s time to
explore the possibilities of saving time and money with your virtualization
project.)
Most x86 computers don’t use their hardware to the fullest capacity because
de facto system design often dictates that you use a single server for a single
purpose. As I mention in the book’s Introduction, virtualization simply uses
“smoke and mirrors” to separate your programs and operating systems
from the hardware on which they run. That way, many virtual machines use
common hardware, and the hardware is far better utilized.
In this chapter, virtual machines, ESX hosts, the benefits of virtulization,
and VI3 are covered. Additionally, the last section describes the major steps
in implementing your virtual infrastructure.
Knowing What You Must
About Virtual Machines
Making as many of your physical machines as possible become virtual is
the end game of virtualization. The more you virtualize (convert physical to
virtual machines), the more benefits you see, and the more you realize how
