I need to configure ADFS as a high-availability solution.
Am I correct in thinking that you need at least SQL Server Standard Edition (we're looking at SQL 2012) installed on both servers so that database mirroring can be configured, i.e. I can't use SQL Express at all on either side)?
I also understand that I need to configure NLB to support the failover. Would this be completed automated?
How long roughly would this take to setup a couple of SQL servers in this configuration and is there any step-through guides available?
