We currently have Sharepoint 2010 foundation with SQL 2012 Express. We are fast approaching the 10gb limit of this SQL version. My question is: If we upgrade to SQL 2012 Standard to get past this limit, what do we need to buy? Even after searching the Internet about this I still can't figure it out. If we get the SQL server standard(not sure where to start), do we also need CALs if it's only used for Sharepoint? It's a standalone virtual server, no farm. Processor is Xeon-e5-2660, 8 cores.
