The value should be about "Exchange servers Core Number" / 8, isn't it ?

For Exchange 2013, we recommend deploying a ratio of 1 Active Directory global catalog processor core for every 8 Mailbox role processor cores handling active load, assuming 64-bit global catalog servers."
The storage Calculator, in our sizing environement, gives us a 51/1 result, there is maybe a mistake ?

Julien
