Turtles vs. Hares
Turtles vs. HaresDue dilligence[Utilization data for all the LPARS, with daily profiles.]I am unaware of anyone that actually goes back to an LPAR later to adjust it. Fire-and-forget seems to be the mantra when creating LPARs. Why would anyone want to do the extra work of collecting utilization data and...
