Introduction to iCOD on nPartitions
HP’s iCOD product is available for both nPartition servers and
non-partitionable HP servers. This document covers iCOD issues that
are unique to nPartition systems.
See the Instant Capacity on Demand (iCOD) and Pay Per Use (PPU)
User’s Guide for complete information about iCOD on all supported
platforms.
iCOD is an optional product that includes an iCOD software bundle and
a corresponding system contract with Hewlett-Packard, which determine
the type of billing for processors you activate and use.
Billing for iCOD-activated processors is calculated on a complex-wide
basis: the total number of activated iCOD processors in all nPars.
HP nPartition systems support two varieties of iCOD: iCOD Purchase,
which enables you to instantly activate and purchase additional
processors as your needs increase; and iCOD Utility, which supports
instantly increasing and decreasing the number of activated processors,
for billing on a pay per use basis.
All nPars in a server complex either must run the same iCOD variety
(purchase or utility) or not run iCOD. If you configure iCOD Utility for
one nPar then you also must configure all other nPars with iCOD Utility.
HP recommends (but does not require) that you configure iCOD
Purchase for all nPars if you configure any nPar with iCOD Purchase.
You cannot configure nPars with both iCOD Utility and iCOD Purchase
in the same server complex.
Unique iCOD Features for nPartitions
HP’s iCOD Purchase and iCOD Utility products have some different
features and behaviors on nPartition servers than iCOD on other
non-partitionable systems.
The following list covers some of these unique features.
• iCOD on each nPar is managed locally and independently.
iCOD commands affect and list iCOD settings for the local nPartition
(the nPar where the commands are run).
