&nbsp;for almost 5TB of total space. <br />
Currently it has roughly about 450ysers and 510GB of the total mailbox store.<br />
The calculator recommends 4 databases. So 5 LUNs total including a recovery LUN 800GB. &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<br />
This is for two mailbox servers in one DAG. &nbsp;I left everything as a default.<br />
Please advice if the calc is correct or a bit too much..
