Good morning ladies & gentlemen,
I have a question about the correct Global catalog sizing for an Exchange 2013 deployment.
On technet page, recommandation is to have a 1:8 ratio of active mailbox cores and global catalog cores.
In the Exchange 2013 sizer, If I have a design with 2 sites, I have the following results :
Number of Processor Cores Utilized : 6
Total Number of Servers / DAG / datacenter : 8
So based on my calculation, 6x8 = 48 then divide by 8 = 6 cores required
The calculator displays : 4 Global Catalog Cores required. Why ?
Thanks for your help & regards.
J.
