There must be at least one core usage right available
for an Instant Capacity cell board you wish to activate. Each active
cell board must have at least one active core. However, this does
not necessarily mean you must acquire additional core usage rights.
No additional core usage rights are required unless the requirement
of a minimum of one core per active cell board could not be met without
acquiring additional core usage rights. That is, if the number of
active cores in an nPartition equals (or exceeds) the number of cell
usage rights, then the purchase of additional core usage rights is
not necessary.

|
 | NOTE: The following examples assume that the number
of Intended Active cores for the nPartition remains constant before
and after the cell board activation. |

Example 6-1 Cell Board Activation Not Requiring Additional Core Usage Rights
For example, consider an nPartition with one active
cell board with all four cores active, and one inactive cell board
with four inactive cores. The number of Intended Active cores for
the nPartition is four. There are no additional core usage rights
available. Activation of the inactive cell board on the complex will
result in two active cores per cell board after a reboot. That is,
the Instant Capacity software distributes the available core usage
rights across the two active cell boards in the partition. The requirement
that at least one core is active on each cell board is satisfied,
so purchase of additional core usage rights is not necessary. Of course,
you may wish to activate additional cores in the partition and if
so, then you should purchase core usage rights at the same time as
the cell usage rights, but it is not required in this situation.
Table 6-1 Cell Board Activation Not Requiring Additional Core Usage Rights
State | Active Cell Board
Cores | Inactive
Cell Board Cores | Notes |
|---|
Before Cell Board Activation | 4 active | 4 inactive | No additional core usage rights are available on the complex |
After Cell Board Activation | 2 active, 2 inactive | 2 active, 2 inactive | No additional core usage rights were required because the number
of core usage rights was greater than the number of active cell boards |
Example 6-2 Cell Board Activation Requiring Additional Core Usage Rights
In a different scenario, activation of an additional
cell RTU can cause the number of core usage rights to be below the
minimum (one active core per active cell board) and necessitate the
acquisition of additional core usage rights. For example, consider
an nPartition with one active cell board containing one active core
and three inactive cores, and one inactive cell board with four inactive
cores. The number of Intended Active cores is one and there are no
available core usage rights on the complex. In this case, purchase
of an additional cell RTU for the inactive cell board requires that
an additional core usage right be purchased in order to meet the minimum
requirement of one core per active cell board.
Table 6-2 Cell Board Activation Requiring Additional Core Usage Rights
State | Active Cell Board
Cores | Inactive
Cell Board Cores | Notes |
|---|
Before Cell Board Activation | 1 active, 3 inactive | 4 inactive | No core usage rights are available on the complex |
After Cell Board Activation | 1 active, 3 inactive | 1 active, 3 inactive | One additional core usage right was acquired because the number of
core usage rights was less than the number of active cell boards |
