Simple question: Not so simple answer

Question: You know any best practice wiki's, blogs, forums, etc for Power7?

Answer: oh my goodness - I need to rewrite several documents - becuse on best practice I know for sure - do not rely on Power5/Power6 best practice for sizing Power7 processor and/or memory. It is a whole new game. And now I start thinking about where to start !! Money mouth

So, my message to you for today - Do not rely on best practice for Power5 or Power6. Look further - especially when system utilization is running consistently at 75%+. (Think of 75% as low border of region yellow; somewhere between 92-97% region red begins).
