Currently I have Exchange 2010 install in a single server ( Physical ) with all the Roles ( CAS, MBX and HUB), I'm planning to migrate the current server to Hyper-V server and make it High available and also keep one server in my Disaster Recovery site in case my primary site is unavailable.
I need advise as below.
- Which version is advised to go with 2010, 2013.
- number of servers( I plan for two CAS each in one location using NLB ) and two MBX each in one location also.
- what will be the LUN configuration since I'm allocating 1 TB for the Exchange DBs for the DAG.
I need a stable and simple setup to keep my mail flow fine in case a single server failed.
