Installing and Managing HP-UX Virtual Partitions (A.02.01)

Introduction
What Is vPars?
Chapter 1 21
Two virtual partitions that have different CPU utilization peak times
can have processors moved between them. For example, a transaction
server used primarily during business hours could have floating CPUs
reassigned overnight to a report server. Such reassignments can be
automated, for example, via cron.
Because vPars assigns specific hardware resources to specific virtual
partitions, a user on the transaction server at night is not affected by the
reports server’s huge consumption of processing power. A virtual
partition uses only the CPUs that you assign to it; CPUs are not
time-sliced across the virtual partitions.
