HP-UX System Administrator's Guide: Overview

• nPartitions can be further subdivided using software partitioning
• vPars only supports instances of HP-UX

Combining Partitioning Technologies for Greater Flexibility
By themselves, the various server partitioning technologies give you a very flexible
compute environment, but you can combine them for even greater flexibility and
control.
The following illustration shows how nPartitions, vPars, and Integrity Virtual Machines
can be combined on a single server to support a large amount of work.
