What Is vPars?
The vPars (Virtual Partitions) product allows you to run multiple
instances of HP-UX simultaneously on one computer by dividing the
computer into virtual partitions. Each partition is assigned its own
subset of hardware, runs a separate instance of HP-UX, and hosts its
own set of applications.Because each HP-UX instance isisolated from all
other instances, vPars provides application and OS (Operating System)
fault isolation. Each instance of HP-UX can be of a different release,
have different patches, and have a different kernel.

NOTE Virtual Partitions versus Hard Partitions
A hard partition is a physical partition of a computer that divides the
computer into groups of cell boards where each group operates
independently of other groups. A hard partition can run a single instance
of HP-UX or be further divided into virtual partitions.
