The software charges can vary according to the license agreement for the individual
products. See your IBM Software Group (SWG) representative for exact details.
On/Off CoD can concurrently add processors (CPs, ICFs, zIIPs, IFLs, and SAPs),
increase the MCI, or both, up to the limit of the installed CPC drawers of an existing server.
It is restricted to twice the currently installed capacity. On/Off CoD requires a contractual
agreement between the customer and IBM.
The customer decides whether to pre-pay or post-pay On/Off CoD. Capacity tokens inside
the records are used to control activation time and resources.
CBU is a concurrent and temporary activation of extra CPs, ICFs, zIIPs, IFLs, and SAPs,
an increase of the MCI, or both.
CBU
cannot be used for peak load management of customer workload, or for CPE. A CBU
activation can last up to 90 days when a disaster or recovery situation occurs.
CBU features are optional, and require unused capacity to be available on the installed
CPC drawers of the backup server, either as unused PUs or as a possibility to increase
the MCI, or both. A CBU contract must be in place before the special code that enables
this capability can be loaded on the server. The standard CBU contract provides for five
10-day tests and one 90-day disaster activation over a five-year period. Contact your IBM
representative for details.
CPE is a concurrent and temporary activation of extra CPs, ICFs, zIIPs, IFLs, and SAPs,
an increase of the MCI, or both.
The CPE offering is used to replace temporary lost capacity within a customer’s enterprise
for planned downtime events, such as during data center changes. CPE cannot be used
for peak load management of the customer workload, or for a disaster situation.
The CPE feature requires unused capacity to be available on installed CPC drawers of the
backup server, either as unused PUs or as a possibility to increase the MCI, or both. A
CPE contract must be in place before the special code that enables this capability can be
loaded on the server. The standard CPE contract provides for one 3-day planned
activation at a specific date. Contact your IBM representative for details.
