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. vPars provides application and OS (operating
system) fault isolation.
