What is vPars?
The vPars (Virtual Partitions) product allows you to run multiple
instances of HP-UX simultaneously on one server or nPartition
by dividing a server or nPartition 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.
