RDS 2019 HA Setup - Remote Desktop Services 2019 High Availability With FS and SQL clustering.

Hi All, 

I am quite new to RDS, I've installed a 2016 instance on VMware vSphere 6.7 without further issues.

I am trying to install an RDS 2019 instance with HA and cannot find much information on how to setup a shared File System and the SQL Cluster instance. 

Configuring this on VMware will be a different issue but would like to ask if you know of any documentation that would guide me with the File system and SQL server setup.

All I could find was Azure based and none On-Premise based information for this item. 

Any help will be appreciated, 

Thank you in advance, 
Eu
