I'm very new to SQL and SSIS, SSAS, SSRS, I have 3 tier SharePoint farm with one SQL Database and one Separate Report server where all SSIS, SSAS, SSRS are going to install, my question is: 1.I have already installed SQL server in SharePoint farm do I need to install SQL server on Report Server too. 2. In Report Server if SQL needs to be installed then, how many drives do I need and size of each drive for 100+ SSRS reports(120+ users). Thank you, Regards.
You only need to have a Sql Database Engine (instance) installed if you plan on placing the 2 Reporting databases which are created during the Reporting Services configuration on the same server as Reporting Services is running. Most installations we see is where Reporting Services and the Reporting Services databases are all on the same server to save in licensing costs but separated from the User Databases.
