Figure 2-3 Server Block Diagram with 2 Virtual Partitions
Each application can run on top of separate OS instances. Instead of a single OS instance owning all the
hardware, the vPars Monitor manages the virtual partitions and their OS instances as well as the assignment
of hardware resources to each virtual partition.

vPars Monitor
For each hard partition, the vPars Monitor manages the assignment of hardware resources to virtual
partitions, boots virtual partitions and their kernels, and emulates certain firmware calls. By emulating
these specific calls, vPars creates the illusion to each HP-UX instance that it is running on a standalone
server, consisting of the hardware that has been assigned to it.
