My company is looking into transitioning from MapInfo to ArcGIS Enterprise ArcPro With Portal. We would like to use Enterprise Geodatabases in Sql Server as well as the Portal Data Stores. The sql server will be hosted on a separate server from the primary ArcGIS Server. Portal will be hosted on its own server. The relational Data Store will be hosted on the primary ArcGIS Server.
What licensing or additional software is needed to connect the sql server as an enterprise geodatabase to the ArcGIS server, Portal server, and Data Store? I understand that an ArcGIS client is needed for the sql server and a sql server client is needed on the ArcGIS server. But I do not know what else is involved. Is a separate ArcGIS license needed for the sql server? Is just a free download needed to configure the sql server and input the primary ArcGIS server license key? Are there specific core requirements? RAM? Disk Space?
