2 Installing or upgrading to HP-UX vPars and Integrity VM
V6.3
2.1 Virtualization Services Platform
The physical server on which HP-UX vPars and Integrity VM is installed is referred to as a VSP
(Virtualization Services Platform). vPars and Integrity VMs are subsequently created on these
installations. The VSP is an HP-UX based system intended to provide virtualization services for vPars
and Integrity VM guest instances that are hosted on it. Consequently, the VSP must not be used as
a general purpose HP-UX server; you must ensure that application workloads are not run on a VSP.
2.2 Hardware requirements for the VSP
The following HP Integrity servers may be used as VSPs for HP-UX vPars and Integrity VM V6.3.
HP Integrity servers
HP Integrity i2 servers
rx2800
Bladesystem
Superdome 2
HP Integrity i4 servers

Superdome 2
VSPs require the following physical resources:
Processors
Adequate number of processors must be available on the VSP for all vPars and Integrity VMs
that are hosted on it.
In addition to providing computing resources for vPars and Integrity VMs, the VSP requires
some processor resources for system operations and processing shared I/O loads from the
guests.
When vPars are used, at least one processor must be dedicated to the VSP; primarily for
interrupt processing of shared I/O resources. Additional processors may have to be dedicated
to the VSP if the shared I/O interrupt load is sufficiently high.
Memory
The host HP-UX operating system installed on a VSP, consumes some system memory when
the VSP is booted with it. The amount of memory that is used is dependent on VSP system
configuration and activated device drivers.
HP-UX vPars and Integrity VM V6.3 reserves additional memory for system virtualization
operations. This is set to a default value of 8% of available system memory at the time HP-UX
vPars and Integrity VM V6.3 is started.
Memory for all vPars and Integrity VMs on that VSP is allocated from the remaining VSP system
memory.
