HP-UX 11i Virtual Partitions (vPars)
Overview
Currently shipping versions:
HP-UX 11i v1 Virtual Partitions vA.03.05
HP-UX 11i v2 Virtual Partitions vA.04.06
HP-UX 11i v3 Virtual Partitions vA.05.04
HP-UX Virtual Partitions (vPars) software partitioning product carves up an individual hard partition or server into several smaller
virtual servers, each with their own operating system, resources, and applications. Any application or operating system-related
failures can only impact or bring down the vPar in which it is executing-without affecting other virtual partitions executing on the
same system. Since vPars simply parses separate resources to different virtual partitions, the technology is simple, with high
performance.
Features
Provides operating system, application and resource isolation within a server or hardware partition
Failure is isolated to that specific virtual partition (vPar); other virtual partitions are unaffected
High performance software partitioning product, due to:
Separate processor core, memory, and I/O H/W resources per partition
Cell local resource support
Resource granularities: processor core, 64 MB memory, I/O slot
Provides operating system parameter independence per virtual partition
Online creation, modification, and deletion of virtual partitions without a system or nPartition reboot.
Affected virtual partitions may need to be re booted.
Individual reconfiguration and reboot
Enables application specific O/S tuning
Applications run the same within a virtual partition as they do in a standalone OS
Dynamic processor migration
Dynamic memory migration across virtual partitions (vPars A.05.01+)
Configuration of virtual partitions allowed from any virtual partition, or from designated virtual partitions, using flexible admin
option (A.03.03+)
Mixed HP-UX 11i vPars supported within an nPartition or HP server

HP-UX 11i Virtual Partitions (vPars)
Overview
Configuration
Hard partitions can contain multiple virtual partitions; however, a virtual partition cannot span multiple nPartitions.
There can be a maximum of 8 virtual partitions per nPartition
Each virtual partition can be supported in an nPartition with a maximum of 8 cells
NOTE: Within a particular nPartition, no 2 of the following 3 technologies can be run at the same time:
Dynamic nPartitions
HP-UX Virtual Partitions
Integrity Virtual Machines
System must have appropriate version of HP UX 11i, and the firmware for that vPars release
Each virtual partition needs:
One or more processor cores
A certain amount of memory
A bootable disk device (may use a combination card)
A network connection (not absolutely required)
Independent storage (may be direct attached or SAN)
Maximum number of virtual partitions varies by system
Any HP-UX 11i v3 virtual partition that wishes to use the following vPars A.05.01 features at initial HP-UX 11i v3 release,
requires a CFW firmware upgrade:
vPars dynamic memory migration
vPars support of HyperThreading on dual-core Intel Itanium 2 processors

Software licensing:
1.
2.
vPars is licensed on a per core basis; for active processor cores within nPartitions or servers running vPars.
Virtualization Licensing provides two options for purchasing HP UX OE or layered software products, (on a per core licensing
basis), when running within a vPar:
Software may be licensed for all of the active physical processor cores in the nPartition or non partitioned server. (This allows
you to run as many instances of the software in the vPar as you desire without requiring additional licenses. This is beneficial if
you intend to run the same software across all or most vPars or if you intend to change the configuration often and don't want
to worry about compliance.)
Software may be licensed for the maximum virtual processor cores that the software will be run on within the vPars. (For
example, if you are running HP OnlineJFS in a vPar with one virtual processor core on a server with four physical processor
cores, you could pay for just one Per Core License. This method will be most beneficial when you intend to run the software on
only a small portion of the nPartition or non partitioned server. When applicable, this new licensing option can significantly
reduce licensing costs for customers versus previous licensing options.)
