I can't seem to find any clear answers to the implications of installing SQL Server 2012 standard edition vs. enterprise in regards to SharePoint 2013.
I understand that to get many of the features you need Enterprise edition of SQL 2012; but, what I can't figure out is if the backend SharePoint SQL 2012 is standard; but, the PowerPivot/SSRS server is Enterprise will we still get the features?
If we have 3 tier SharePoint farm, one of those tiers is for the SQL Server database backend. If that SQL instance is 2012 standard and we add another server to the farm w/ SQL 2012 Enterprise to handle the tabular models, PowerPivot, and SSRS in integrated mode will we still get the features?
Or, can we (should we) install Enterprise 2012 as the SharePoint database backend and let that instance triple down as also the PowerPivot and SSRS instance?
