Hello,
The Symantec Endpoint Protection Manager includes an embedded database, and this is the only choice in Small Business Edition. In the enterprise version, you may use the embedded database or one of the following versions of Microsoft SQL Server:
- SQL Server 2005, SP4
- SQL Server 2008
- SQL Server 2008 R2
- SQL Server 2012
Note: If you install the Symantec Endpoint Protection Manager and the SQL database on the same computer, a minimum of 4 GB of RAM is recommended.
