iCOD component See Instant Capacity component.
iCOD processor See Instant Capacity core.
inactive cell A cell that is not available for use by software running on an nPartition. This term is usually
used to describe a cell that has the following status (though any cell that is not active is by
definition inactive).
• The slot is present and is populated.
• Power is enabled.
• Boot-is-blocked.
• The cell is assigned to an nPartition.
inactive
nPartition
An nPartition in which all of its cells are inactive.
inactive processor A processor in an Instant Capacity system that is currently inactive. Inactive processors without
usage rights are capable of activation by use of the icapmodify command (or by use of the
vparmodify command in a virtual partition). An inactive processor is also referred to as a
“deactivated processor”.
Instant Access
Capacity
Also called IAC. An amount of temporary capacity included with the purchase of an Instant
Capacity component.
Instant Capacity
(iCAP, iCOD)
Also called iCAP, and formerly known as Instant Capacity On Demand, or iCOD. The HP
Utility Pricing Solutions product that allows you to purchase and install additional processing
power through the use of a two-step purchase model. Initially, you purchase system components
(processors, cell boards, memory) at a fraction of the regular price because the usage rights are
not included. These Instant Capacity components are inactive but installed and ready for use.
When extra capacity is needed, you pay the remainder of the regular price for the usage rights
to activate the components. If the regular price for the component is reduced by the time the
usage rights are purchased, the remainder price is proportionally reduced, providing additional
savings.
Instant Capacity
component
Also called a component without usage rights, an Instant Capacity component is a core, cell
board or memory that is physically installed in an Instant Capacity system but is not authorized
for use. Before it can be used, an RTU (see Right to Use) must be purchased and a codeword
applied to the system.
Instant Capacity
core
Also called a core without usage rights, a core that is physically installed in an Instant Capacity
system, but does not have usage rights, nor is it activated. After obtaining usage rights, Instant
Capacity cores can be turned on by the Instant Capacity software or during installation. Cores
with usage rights are activated with the icapmodify command (or the vparmodify command
in a virtual partition) while HP-UX or OpenVMS is running.
migrating cores The process of activating and deactivating cores across partitions or across members in a GiCAP
group for load-balancing. See “Load-Balancing Active Cores” (page 64) for more information.
monarch
processor
This is the main controlling core from the perspective of the operating system. This core is
designated as CPU 0. The LPMC monitor does not deactivate/replace a failing monarch
processor. This is also known as the boot processor.
nPartition Also known as nPars. A partition in a cell-based server that consists of one or more cells, and
one or more I/O chassis. Each nPartition operates independently of other nPartitions and either
runs a single instance of an operating system or is further divided into virtual partitions.
online activation The ability to activate a deactivated core while HP-UX or OpenVMS is running. No reboot is
required. This is done by using the icapmodify command, or the vparmodify command in
a virtual partition. Online activation is the default behavior of the Instant Capacity software.
partition A subset of server hardware that includes core, memory, and I/O resources on which an operating
system can be run. A partition can be either a software partition (virtual partition) or a hard
partition (nPartition). This type of partitioning allows a single server to run an operating system
independently in each partition with isolation from other partitions.
Pay per use Also called PPU. The HP software product, which is a part of the HP Utility Pricing Solutions
program, that has a pricing model in which you are charged for the processing usage. You
acquire a specific hardware platform, and number of cores, and are charged for usage of the
cores depending on system demand.
