units can be permanently activated by purchasing an activation feature called Capacity
Upgrade on Demand (CUoD) and entering the provided activation code on your server.
With the CUoD offering, you can purchase additional static processor or memory capacity
and dynamically activate them when needed, without requiring you to restart your server or
interrupt your business. All the static processor or memory activations are restricted to a
single server.
Capacity Upgrade on Demand can have several applications to allow for a more flexible
environment. One of its benefits is to allow for a given company to reduce the initial
investment on a system. Traditional projects using other technologies require that the a
system is acquired with all the resources available to support the whole lifecycle of the
project. This might incur in costs that would only be necessary on later stages of the project,
usually with impacts on software licensing costs and software maintenance.
By using Capacity Upgrade on Demand a company could start with a system with enough
installed resources to support the whole project lifecycle but only with enough active
resources necessary for the initial project phases. More resources could be added along with
the project, adjusting the hardware platform with the project needs. This would allow for a
company to reduce the initial investment in hardware and only acquire software licenses that
are needed on each project phase, reducing the Total Cost of Ownership and Total Cost of
Acquisition of the solution. Figure 2-17 shows a comparison between two scenarios: a fully
activated system versus a system with CUoD resources being activated along with the project
timeline.

The Table 2-16 on page 62 lists the static processor activation features that are available for
the Power E870 and Power E880.
