I have having difficulties setting the value of Number of non-Lagged Database Copies in Secondary Datacenter to 3.
We are looking to create an environment with 6 Exchange 2019 servers, spread evenly across 2 datacenters.
I have set Site Resilience User Distribution Model to Active/Active
I have set Total Number of non-Lagged Database Copies within DAG (include Active) to 6 (each server will have a copy of each database)
To spread the database copies across the 6 servers, half of them need to be in the secondary datacenter, but the spreadsheet only allows me to choose 0, 1, or 2 for Number of non-Lagged Database Copies in Secondary Datacenter.
UPDATE:
I un-hid the worksheet named Variables and added additional numbers to the Standby Datacenter DB Copies column (col L). The numbers appeared to be static, not calculated by a formula. Hopefully other formulas throughout the calculator are not limited to 2 or less for this input.
