Exchange Server Role Requirements Calculator: DAGs required
I have a quick question regarding the “Exchange Server Role Requirements Calculator”. I have a medium sized Exchange 2010 Environment that I would like to upgrade to Exchange 2016. The current Exch...

Finally, I think I know what the problem is - My SPECINT2006 value was way off - I downloaded this tool "Exchange Processor Query Tool" https://gallery.technet.microsoft.com/Exchange-Processor-Query-b06748a5 and it calculated my SPECINT2006 value to be 645. Now the Calculator works correctly and recommends 1 DAG :-)

Jan 24, 2018The calculator also assumes you are calculating for 4 copies of DB and you should check the second tab to see the calculation which it did. also the database copy layout tab

Here are the values. I understand that you would have 4x Database Copies per server - That is correct and there are 3 copies of a Database instance replicated - Two on the Primary Datacenter and One on the DR Datacenter.
But where do the 324 copies come from? I know that 9 x 36 = 324 - But that suggests I have 9 DAGs
Surely then the Database Copy Instance Configuration values should be multiplied by 9...?I still don't get how the Calculator can recommend I use 9 DAGs?
Database Copy Configuration
Number of Database Copies/ Server = 4
/ DAG = 36
/ Environment = 324
Database Copy Instance Configuration
Number of HA Database Copy Instances / DAG/ Primary Datacenter = 2
/ Secondary Datacenter = 1
Total = 3
