Hello,
I used to run my SP2010 and SQL 2008 R2 where all databases were mirrored using async mirroring.
Now I am planning a SP2013 and SQL 2012 upgrade.
Is there any other advantage of Always on ... as compared to mirroring other than the fact that more than 1 copies will be possible?
My understanding is that always on requires windows enterprise edition so is more expensive than mirroring which can be setup on windows standard (sql enterprise).
When I read this article, it seems to me that more SP databases support Mirroring rather than Always on when it comes to Async commits.

I wonder why because one would expect that the Always on would be more optimal and thus better.
In my organization, the DBAs like async more because it results in fewer alerts because of suspended mirorring. So making them support a sync session is harder because sync results in more alerts where mirroriong gets suspended because of high number of transactions or network clogging.
Any thoughts?
