I am trying to provision a space for Exchange 2010. For some the Exchange 2010 Mailbox Server Role Requirements Calculator
for almost 5TB of total space.
Currently it has roughly about 450ysers and 510GB of the total mailbox store.
The calculator recommends 4 databases. So 5 LUNs total including a recovery LUN 800GB.
This is for two mailbox servers in one DAG. I left everything as a default.
Please advice if the calc is correct or a bit too much..
