HP-UX vPars and Integrity VM V6.3 Administrator Guide

3 Configuring VSP
VSP is the manageability platform for vPars and VMs, running the standard HP-UX 11i v3 OE. VSP
has a controlled environment tuned for supporting the vPars and Integrity VM V6 product
functionality. DO NOT install any application on the VSP, that is CPU or memory or IO intensive
in nature. Running such applications on the VSP can cause unpredictable behaviour.
The product startup scripts located at /sbin/init.d/ configure the VSP resources (cores and
memory) during every reboot of VSP. There is no explicit configuration change needed on the VSP,
unless otherwise documented.
Starting from vPars and Integrity VM V6.2, you can run both vPars and VMs concurrently on the
VSP (mixed mode environment).
Figure 3 (page 37) shows the different layers in a VSP.
