4.2.4 Number of Virtual Partitions per nPartition
The recommended number of virtual partitions per nPartition is equal up to one-half the installed
CPUs (processing cores) in the nPartition in order to meet I/O and memory requirements and to
allow for cores that can be used for dynamic processing core migration.
The maximum number of virtual partitions per system is the number of processing cores given
the limits specified in Table 4-8.
