What Is vPars?
The vPars (Virtual Partitions) product allows you to run multiple
instances of HP-UX simultaneously on one hard partition
1
by dividing
the hard partition further into virtual partitions. Each virtual
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 is isolated 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.
