3.3 Capacity on Demand
The 595 server can be configured with inactive processors and memory, which can be
activated at a later date when they are needed. This feature is called Capacity on Demand
(CoD). The options for activating CoD resources are listed in Table 3-3.
Table 3-3 CoD options for processors and memory
Option
Permanent activation
On/Off
Utility CoD
Trial CoD
Capacity Backup (CBU)
Note: CoD processors that have not been activated are available to the 595 server for
dynamic processor sparing. If the server detects the impending failure of an active
processor, it attempts to activate one of the unused CoD processors and add it to the
running system configuration. This process does not affect the licensed number of
processors for your system.
When processors are temporarily enabled using the On/Off, Utility CoD, Trial CoD, or CBU
option, no additional license charges are applicable for the AIX and IBM i operating systems
or IBM i 5250 Enterprise Enablement. Different rules might apply for Linux for Power. Consult
with your Linux vendor regarding the temporary activation of processors for Linux partitions.
