I am trying to build a SQL 2012 failover cluster with Windows 2012. This will be a AAAP cluster. Can I build the 3 active nodes with different cores and RAM as followin or all 3 nodes have to be identical?
IMHO they should be roughly the same if not identical - but that won't stop you from having different amounts of CPU/Ram per node. You can absolutely build what you are proposing - I would add a startup procedure inside of the instances and have them check
the # of CPUs and Amount of Ram and configure themselves accordingly.
