With this configuration, the estimated CPU usage due to Active Memory Expansion is approximately 0.58 physical processors, and the estimated overall peak CPU resource required for the LPAR is 3.72 physical processors. This sample partition has fairly good expansion potential A nice sweet spot for this partition appears to be 45% expansion 2.5 GB gained memory Using about 0.58 cores additional CPU resource Tool included in AIX 6.1 TL4 SP2 Run tool in the partition of interest for memory expansion. Input desired expanded memory size. Tool outputs different real memory and CPU resource combinations to achieve the desired effective memory.
