Chapter 16 Instant Capacity (iCAP)

Introduction
HP Instant Capacity software provides the ability to instantly increase or decrease computing
capacity on specified HP enterprise servers. It is a part of the HP Utility Pricing Solutions
program.
With Instant Capacity, you initially purchase an HP enterprise server with a specified amount of
active processing capacity, and a specified amount of inactive processing capacity. Processing
capacity consists of the system components:
 Processors containing cores
 Cell boards
 Memory
For each type of component, the number of components that can be active is equal to the number
of usage rights applied to the complex for that type of component. Components that are
purchased with a part number identifying them as “Instant Capacity” and without the label
“Right to Use” come without usage rights. Components that are not labeled “Instant Capacity”
implicitly include usage rights that can be applied to any component of that type that is installed
on the complex.
Prior to activation of an inactive component, you must obtain additional usage rights. The
fundamental method is to purchase usage rights by purchasing the appropriate Instant Capacity
products that include the label “Right to Use (RTU)”. HP then supplies an RTU codeword. When
the codeword is applied to the HP enterprise server, the inactive component can be activated.
Additional methods for activating components for which usage rights have not been purchased
include:
 TiCAP – temporary use of iCAP hardware components
 IAC – Instant Access Capacity (TiCAP included with purchase)
 GiCAP – allows to share capacity between different servers
Most of the provided information is collected from several sources, especially from the HP
Instant Capacity User Guide and the HP Instant Capacity Release Notes, available at
www.hp.com/go/hp-icap-docs. Please note that this chapter should only be used as short
reference and is not designed to replace the complete and official guides.
Instant Capacity must be run on a partitionable system. In an Integrity Virtual Machines (VM)
environment, Instant Capacity software provides meaningful functionality only on the VM Host
system; it does not run on a virtual machine (also known as a “guest”).
Instant Capacity consists of the following main elements:
 Instant Capacity system hardware (including cells, cores, and memory)
