I have a SharePoint 2010 farm that consists of four servers - two WFE servers and two app servers. The WFE servers are the only servers that serve requests to the portal (which is behind a load balancer). The app servers host CA and assorted service applications.
I want to configure SSRS 2008 in SharePoint integrated mode. I already have a SSRS 2008 server built that has an instance of SSRS in non-integrated mode, and I would like to repurpose this server for the SharePoint reporting. My questions are:
1) Do I have to add the SSRS server as a WFE in the existing farm? The documentation claims that I do, but is it possible to have the Reporting Services add-in installed on an existing WFE and then it just points to the SSRS server?
2) If I do need SSRS on a server in the farm, does it have to be a WFE, or can I install it on one of the app servers, keeping in mind that they never serve requests directly to clients?
