2 HP-UX Virtualization Technologies
Enterprise computing is now heavily focused on enabling you to use your computing resources
as efficiently as possible by extracting the most performance from each of your server’s resources.
Many technologies are available to help you configure HP enterprise servers to suit almost any
need, and to adjust your configuration as your computing needs change with minimal disruption
to your business.
Collectively, these technologies are known as virtualization technologies. They allow you to group
and divide your physical computing resources to function as customized virtual resources in
order to properly size them for maximum efficiency.
This chapter discusses many of the key virtualization technologies available with HP-UX, what
resources they allow you to configure, and how they relate to each other.
Understanding Virtualization Technologies
Because there are now so many ways to configure the resources of your systems and your network,
it can be a bit confusing trying to determine which technology (or combination of technologies)
best suits your needs.
This document provides general information about each of the technologies and how they relate
to each other. Where possible, it provides pointers to where you can find more detailed
information.
In addition, HP offers technical consulting services to help you tailor these virtualization
technologies to best suit your needs.
Virtualization Technology Categories
Virtualization technologies and their associated products fall into six basic categories based on
the number of cores, servers, and operating system instances involved. The matrix in
Figure 2-1 “Virtualization Technology Categories Matrix” shows these categories and how they
align with processing cores, servers, and operating system instances.
