Exchange 2010–Blackberry IOPS and CPU overhead
Right from a discussion internal reflexions (thanks to Ross Smith IV and Brian Day for their help on putting metrics down), here is the final statement.
Based on BES documentation :
We calculated that in summary based on their whitepaper for E2010:
IO Multiplication Factor: 2.0
Megacycle Multiplication Factor 1.5
Use these factors in your calculations, for example in the Exchange 2010 Storage Calculator.
