Figure 2-9 shows a comparison between two scenarios: A fully activated system versus a
system with CUoD resources being activated along with the project timeline.
Figure 2-9 An example of Capacity Upgrade on Demand usage
Table 2-12 lists the processor activation features for the Power E850C server. Each feature
code activates a single processor core. You cannot activate more processor cores than are
physically installed in the server.
Table 2-12 Permanent processor activation codes for Power E850C
Permanent activations for memory features in the Power E850C can be ordered by using the
following feature codes:
#EMAA for 1 GB activation of memory
#EMAB for 100 GB activation of memory
These feature codes are the same regardless of the capacity of the memory CDIMMs
installed in the system. You cannot activate more memory capacity than is physically installed
in the server.
2.6.2 Elastic Capacity on Demand
With the Elastic CoD offering, you can temporarily activate and deactivate processor cores
and memory units to help meet the demands of business peaks such as seasonal activity,
period-end, or special promotions. Elastic CoD enables processors or memory to be
temporarily activated in one day increments as needed. These activations cover a period of
24 hours from the time the activation is enabled on the system. When you order an Elastic
CoD feature, you receive an enablement code that allows a system operator to make
