Hi, I'm moving from a 2007 environment with one Primary and one secondary site server, each in a east/west datacenter. We then have a Distro Point in each of our 12 offices for local package caching, and boundaries set so east servers are in one site and west in the other. Can I mirror this design in 2012 or do I need a CAS in front of the Primary. Everything I have read about building a Standalone Primary doesn't mention if you can add Secondary Site servers beneath it.
Also, what data is stored within the Secondary Site SQL database? Everything I read says it does indeed participate in Database Replication, but doesn't say what specifically is being replicated. I am trying to decide if I should give it a real (off box) SQL server or be lazy and go with SQL Express.
Thanks,
