SQL Always On for FIM

Question

I wasn't able to find any information regarding the support of SQL Always On
Does FIM support SQL Always On? If not what should I use? Cluster? Mirroring?

As Peter says: clustering is supported, mirroring is not, always on database availability groups are not, log shipping is not. Automatic failover with mirroring or database availability groups will not work. Mirroring itself works, just not the failover.
Albeit you have a big performance hit even in asynchronous mode. Ditto for Availability groups. Log Shipping works, but you do have to pay attention to the management of the log. Again, Mirroring, Availability Groups and Log Shipping are not supported by Microsoft
FIM Product group but they will work to the extent described and with the caveats described. So think carefully on what you want to do, being in an unsupported position isn't fun. Clustering can accomplish the goal of high availability. If I had to pick one
for providing DR in case of site failure I would pick log shipping. But again not supported and you must pay attention to your log management or you could suffer performance hits.
