HP Instant Capacity Version 10.x User Guide (762794-001, March 2014)

separately. It provides an immediate buffer of temporary capacity in case extra capacity is
needed before there is time to purchase an RTU or a TiCAP codeword, or to set up a GiCAP
group on an HP-UX system.
IMPORTANT: It is always a good idea to keep some quantity of temporary capacity in reserve.
Purchase of codewords may take one or more days, so having a buffer of temporary capacity
allows you to avoid delays in activation of additional cores. Instant Access Capacity provides this
buffer initially, but as that capacity is depleted, ongoing purchases of additional temporary capacity
are recommended to replenish it.
The iCAP software product is a part of the HP Utility Pricing Solutions (formerly On Demand
Solutions) program.
This document provides you with the most recent information about using the iCAP version 10.x
