I am using latest 10.5 version as on 10th November 2020 for Exchange 2019 sizing.
Design consideration
1. Physical server - Yes
2. Site resilience - Yes
3. Total Number of non-Lagged Database Copies within DAG (include Active) - 3
4. Number of non-Lagged Database Copies in Secondary Datacenter - 1
5. Five server in Primary site and 3 in DR
6. Total number of mailboxes - 17600
7. Site Resilience User Distribution Model - Active/Passive
8. Users profile
I have found following bugs
1. When increasing size of Data Overhead Factor or Volume Free Space Percentage or both, there in no change in DB / logs size in volume requirement
2. Not showing proper Transport Database Space requirement in role requirement sheet. If I set site Site Resilient Deployment to NO, then it is showing Transport Database Space, but when I set Site Resilient Deployment to YES, then its showing 0 GB size.
