Few days ago we wrote about new version of Exchange 2010 Server Role Requirements Calculator which has fixed CAS and HT memory calculations formulas to not report #NAME when designing site resilient topologie.
Now we have new version, on 06/07/2013 Exchange 2010 Server Role Requirements Calculator version 20.8
This version has fixed an error with secondary CAS CPU calculations.
