Using iCAP memory
The iCAP memory is offered in units of 16 GB, and the RTU is available in units of 4 GB. During
the time of activation, you must purchase enough iCAP RTUs to activate all the memory on the cell
blade. After the purchase, the iCAP cell blade can be turned on. You must reboot the partition on
which the iCAP memory is activated for the iCAP changes to take effect. The cores in the cell blade
with inactive memory need not be activated for the memory to be activated. After adding a cell
blade to a partition to activate the memory, you must adjust the number of active cores to ensure
compliance. Figure 17 describes the configuration options for iCAP memory.
