HP-UX Virtual Partitions 6.0 Administrator Guide

3 Planning your system for vPars v6.0
When planning your system for vPars v6.0, it is important to consider the following aspects:
• Configuration of the virtual partitions.
• The required number of virtual partitions.
• The names of the virtual partitions.
• The required amount of processing cores.
• The memory required for each vPar.
• The I/O bandwidth requirement for networking and mass storage.
• The types and amounts of I/O required.
• The resources needed for the VSP (cores, memory, and I/O).
• IP addresses for the remote/virtual consoles.
Configuration of the virtual partitions
Before you install vPars, you must have a plan of how you want to configure the virtual partitions
within your server.

NOTE: After a resource, such as a CPU, memory, or I/O is assigned to a virtual partition, it can
no longer be assigned to other virtual partitions. This is true regardless of whether the virtual
partition is active or inactive. However, the configuration for an inactive virtual partition can be
suspended. After suspending the virtual partition, the resources for that virtual partition can be
assigned to other virtual partitions. For more information about suspending a vPar configuration,
“Suspending a vPar configuration” (page 46).
Number of virtual partitions
The maximum number of virtual partitions per system is determined by the number of processing
cores and the availability of sufficient memory to support the operating environment of each vPar.
In an 8 socket 32 core BL890c i2, you can create up to 31 virtual partitions, with each of them
having one dedicated physical processor core. Or, you can create a single virtual partition with
31 cores on that same server.
