4.4 Types of Capacity on Demand

Capacity on Demand for Sserver p5 systems with dynamic logical partitioning
(dynamic LPAR) offers system owners the ability to non-disruptively activate
processors and memory without rebooting partitions. CoD also gives Sserver
p5 owners the option to temporarily activate processors to meet intermittent
performance needs and to activate additional capacity on a trial basis.
IBM has established four types of CoD offerings on the p5-590 and p5-595
systems, each with a specific activation plan. Providing different types of CoD
offerings gives clients flexibility when determining their resource needs and
establishing their IT budgets. IBM Global Financing can help match individual
payments with capacity usage and competitive financing for fixed and variable
costs related to IBM Capacity on Demand offerings. By financing Capacity on
Demand costs and associated charges together with a base lease, spikes in
demand need not become spikes in a budget.
After a system with CoD features is delivered, it can be activated in the following
ways:
Capacity Upgrade on Demand (CUoD) for processors and memory
On/Off Capacity on Demand (CoD) for processors and memory
Reserve Capacity on Demand (CoD) for processors only
Trial Capacity on Demand (CoD) for processors and memory
The p5-590 and p5-595 servers use specific feature codes to enable CoD
capabilities. All types of CoD transactions for processors are in whole numbers of
processors, not in fractions of processors. All types of CoD transactions for
memory are in 1 GB increments. The CoD activation process is addressed in 4.6,
"Capacity on Demand activation procedure" on page 91, and the associated
feature codes are summarized in 4.11, "Capacity on Demand feature codes" on
page 108.
Table 4-2 provides a brief description of the four types of CoD offerings, identifies
the proper name of the associated activation plan, indicates the default type of
payment offering and scope of enablement resources. The payment offering
information is intended for reference only; all pricing agreements and service
contracts should be handled by your IBM representative. A functional overview of
each CoD offering is provided in the subsequent sections.
