Using HP Instant Capacity
As mentioned in the previous sections, acquiring and using iCAP resources is a two-step process,
whereby an iCAP system is purchased and installed or a regular system is upgraded with iCAP
components. In either case, the iCAP resources are on-site—in the user’s system—inactive, but ready
for use. When the iCAP resources are needed, the appropriate RTUs are purchased and the
components are activated.
A trouble-free Instant Capacity operation involves both installing the necessary IT infrastructure and
setting up the appropriate organizational processes.
Figure 2 shows the key elements of an Instant Capacity operation and the process for activating
Instant Capacity components.

The elements of an Instant Capacity operation include:
• The iCAP server containing the various iCAP components.
• iCAP software (part of HP-UX), which is running in the iCAP server and is the master control element
for activating and deactivating components and tracking and managing such actions. This software
also tracks information, such as the number of processors and cell boards, the amount of memory
that is active and inactive, and, in the case of TiCAP, how much time has been used and how much
remains.
