This independence includes both hardware and software isolation from other nPartitions. Virtual Partitions (vPars), covered in Chapter 16, “Virtual Partitions,” have full software isolation from one another but not hardware isolation. nPartitions have both software and hardware isolation from one another. An nPartition can be divided into multiple vPars.

Integral to working on a cell-based system and performing nPartition-related work is the ...
