HP System Partitions Guide: Administration for nPartitions, rev 5.1 5
9. Processor Instant Capacity on Demand (iCOD) on page 399
This chapter covers using Hewlett-Packard’s processor iCOD
(Instant Capacity on Demand) product on nPartitions.
iCOD is an optional software product that enables you to instantly
increase or adjust processing power within nPartitions. As you need
more or fewer processors, you use iCOD tools to adjust the number of
activated processors in the nPartition.
10. Processor Sets (Psets) on nPartitions on page 421
This chapter describes how to use and manage processor sets (Psets)
on nPartition systems.
Using Psets, you can create multiple independent processor groups
in an nPartition. Each Pset has its own processors, schedules, and
attributes. Because Psets are dynamic, you can create, modify, and
destroy Psets instantly as your system needs demand.
11. Virtual Partitions (vPars) Management on nPartitions on page 443
This chapter describes how to create, configure, and manage HP’s
Virtual Partitions within an HP Superdome nPartition (hard
partition) system environment. Each Virtual Partition can boot a
single instance of the HP-UX 11i operating system.
The HP Virtual Partitions (vPars) software is an optional feature
that you can use to further subdivide a server’s resources into
multiple, smaller virtual machines through software partitioning.
By configuring multiple vPars within an nPartition, you can boot
multiple instances of HP-UX 11i in a single nPartition.
