Hi ThomasStensitzki-MVP ,

I am using Calculator v10.5 and do not have any issues with Custom Maximum Database Size either, I am just curious why with Maximum Database Size Configuration: Default and High Availability Deployment: Yes the calculator recommends maximum database size as 200 GB (two servers, two copies, so RAID deployment).

This is also mentioned in this article as "The recommended maximum limit of 2TB for JBOD deployments, and 200GB for RAID deployments will be enforced by default. ".

I can understand the reasons behind recommending 200 GB maximum database size for standalone deployments, however can not why the RAID deployment with HA has recommended max db size 200 GB as opposed to 2 TB with JBOD with HA.
