After a power enterprise pool is created, the HMC can be used to perform the following
functions:
Mobile CoD processor and memory resources can be assigned to systems with inactive
resources. Mobile CoD resources remain on the system to which they are assigned until
they are removed from the system.
New systems can be added to the pool and existing systems can be removed from the
pool.
New resources can be added to the pool or existing resources can be removed from the
pool.
Pool information can be viewed, including pool resource assignments, compliance, and
history logs.
In order for the Mobile activation features to be configured it is necessary that a a power
enterprise pool is registered with IBM as well as the systems which are going to be included
as members of the pool. Also it is necessary that the systems have the feature code #EB35
for mobile enablement configured and the required contracts must be in place.
The Table 2-18 lists the mobile processor activation features that are available for the
Power E870 and Power E880.

The Table 2-19 lists the mobile memory activation features that are available for the
Power E870 and Power E880.

2.4.3 Elastic Capacity on Demand (Elastic CoD)
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 was previously called On/Off CoD. When you
order an elastic CoD feature, you receive an enablement code that allows a system operator
to make requests for additional processor and memory capacity in increments of one
processor day or 1 GB memory day. The system monitors the amount and duration of the
activations. Both prepaid and post-pay options are available.
Charges are based on usage reporting that is collected monthly. Processors and memory
may be activated and turned off an unlimited number of times, when additional processing
resources are needed.
