Special Considerations
Implications of Removing a Cell from an Instant Capacity System
Appendix A128
In the above example, because the removed cell causes the complex to be
out of compliance, temporary capacity begins to be debited at the rate of
two processor-hours per hour.
Temporary Instant Capacity (TiCAP) allows for increased capacity, even
in the presence of a cell hardware failure, which necessitates the removal
and repair of a cell. Removal of a cell, followed by a reboot of the partition
it was assigned to, results in a maximal number of active processors in
the partition (subject to the configured intended number of active
processors), while the maximum number of unlicensed processors are
relegated to the removed cell. During the period when the cell is absent,
temporary capacity is consumed for each (newly missing) unlicensed
processor that was shifted to the removed cell. Having additional
Temporary Instant Capacity allows for increased capacity during rare
hardware failures that would otherwise not have been possible.
