SQL Server Snapshot Replication and SRDF compatability
I'd check with EMC's tech support, however I seriously doubt anything at the SAN level will have an effect on SQL Server snapshots themselves. 

Snapshots at the software layer are simply files that are handled just like any other file at the SAN hardware level. 

Our Dell SAN has some software that integrates with SQL Server to allow you to create snapshots from SQL Server Management Studio, but again, that is a snapshot of the entire file system - not a specific database file.
