processors on the Eserver i5 550, 570 and 595 and iSeries 825, 870, and 890
servers. Any and all of the inactive processors installed in the server can be
activated as additional permanent or temporary capacity. This is of significant
value for customers who want to add capacity without disruption. There are some
differences between the capacity on demand implementation for the different
models.
IBM Eserver i5 570 and 595 models have the additional ability to activate
memory on demand.
To take advantage of Capacity on Demand, and On Demand Memory you must
purchase a configuration that includes the inactive processor capacity or
memory.

See “Capacity on Demand upgrades” on page 313 for considerations involving
Capacity on Demand upgrades.
Capacity On Demand Models 550, 570, 595, 825, 870, and 890
All IBM Eserver i5 550, 570 and 595 and certain iSeries 825, 870, or 890
servers comes with extra processor capacity built into the server. This extra
capacity, known as
inactive (or standby) processors, can be activated
permanently or temporarily.
Appropriately configured Eserver i5 570 and 595’s also have extra memory
capacity that can be activated permanently or temporarily
Capacity Upgrade on Demand (permanent capacity)
CoD is the iSeries offering for permanently activating capacity. When one or
more activation features are ordered, an activation code is generated and
shipped to the customer (mailed and posted on the Web). The activation code
(think of it as a capacity key) must be entered on the proper server screen, and
the newly activated processors are ready to use. No initial program load (IPL) is
required. The permanently activated processors simply need to be assigned to a
partition prior to use, regardless of whether the server is configured for logical
partitioning.
Activating additional processors also requires an additional OS/400 license
entitlement to be purchased for every processor or part of processor used by
OS/400. This is ordered via a chargeable feature of OS/400 (5722-SS1).
