2.4.4 Utility Capacity on Demand (Utility CoD)
Utility CoD automatically provides additional processor performance on a temporary basis
within the shared processor pool.
With Utility CoD, you can place a quantity of inactive processors into the server’s shared
processor pool, which then becomes available to the pool's resource manager. When the
server recognizes that the combined processor utilization within the shared processor pool
exceeds 100% of the level of base (purchased and active) processors that are assigned
across uncapped partitions, then a Utility CoD processor minute is charged and this level of
performance is available for the next minute of use.
If additional workload requires a higher level of performance, the system automatically allows
the additional Utility CoD processors to be used, and the system automatically and
continuously monitors and charges for the performance needed above the base (permanent)
level.
Registration and usage reporting for utility CoD is made using a public website and payment
is based on reported usage. Utility CoD requires PowerVM Standard Edition or PowerVM
Enterprise Edition to be active.
If a Power E870 or Power E880 server uses the IBM i operating system in addition to any
other supported operating system on the same server, the client must inform IBM which
operating system caused the temporary Utility CoD processor usage so that the correct
feature can be used for billing.

2.4.5 Trial Capacity on Demand (Trial CoD)
A
standard request
for Trial CoD requires you to complete a form including contact information
and vital product data (VPD) from your Power E870 or Power E880 system with inactive CoD
resources.
A standard request activates two processors or 4 GB of memory (or both two processors and
4 GB of memory) for 30 days. Subsequent standard requests can be made after each
purchase of a permanent processor activation. An HMC is required to manage Trial CoD
activations.
An
exception request
for Trial CoD requires you to complete a form including contact
information and VPD from your Power E870 or Power E880 system with inactive CoD
resources. An exception request will activate all inactive processors or all inactive memory (or
all inactive processor and memory) for 30 days. An exception request can be made only one
time over the life of the machine. An HMC is required to manage Trial CoD activations.
