Density on Power 7

Keep your minimum core allocations to a tenth of a core on AIX and leave lpars uncapped. After you get your cpu utilization up to 20% at the Frame/Box level then think about raise minimums.

If you go big out the gate you will limit the total number of LPARS as LPARS will not boot if the combined minimum of lpars exceeds the cores available in the frame less vio allocations.
