This should be easy, but the MS docs are not clear.
The docs:
http://msdn.microsoft.com/en-us/library/cc645993%28v=SQL.100%29.aspx
Indicate that in Standard edition, the only supported mirroring is "safety full only"
Taken together with this document:
http://technet.microsoft.com/en-us/library/ms191456(v=sql.105).aspx
The answer would seem to be:
In SQL Server 2008, async, high performance mirroring is only available in Enterprise Edition
Correct?
Best Answer
In the first document you list, it is clearly stated that Asynchronous Mirroring is only supported in the Enterprise Edition of SQL Server 2008.
Synchronous Mirroring is available in the Standard Edition.
