Multi SQL Environment w EV Reporting

I am deploying EV in an environment w 4 SQL Servers. One server will have Directory, Auditing, Monitoring, One will have DA Databases. and the other 2 will have Vault Store Databases and FP Databases.

My question.. Do I have to install SQL/EV Reporting and point to all 4 SQL Servers, or does the Auditing, Monitoring, Directory know where to get DA and Vault Store data, thus just needing SQL/EV Reporting installed on the one server.

Thanks for any guidance.
