is capable of supporting its own operating system

. The

term nPartitions derives from algebra, where the “n”

refers to a variable number, indicating that you can

group (and regroup) the cell boards in your system in

different ways to create varying numbers and sizes of

partitions (to best suit your needs).

The smallest unit of construction in an nPartition is a

cell board (that is, you cannot use hardware

partitioning to subdivide the resources of a cell board,

assigning them to more than one partition). To do that,

use Virtual Partitions (see vPars below).

nPartitions can be conﬁgured and managed using the

ParMgr tool (see parmgr (1M), or by various command

line tools. The following manpages describe nPartition

commands (for use from the command line):

Extensive information on using and conﬁguring

nPartitions is located in the HP System Partitions

Guide.

PPU Closely related to ICOD, the Pay-Per-Use technology

allows you to pay for your HP-UX-based equipment

based on your actual usage rather than by purchasing

hardware directly. Detailed information on ICOD and

PPU can be found in Instant Capacity on Demand

(iCOD) User’s Guide for Version B.05.00 (see the “On

Demand Solutions (IDS)” section of

http://docs.hp.com/hpux/netsys).

1. Multiple instances of HP-UX can even be run in an nPartition by

using virtual partitions to further subdivide the resources of the

nPartition.
