I have 5pcs. IBM System x3650(7979 - ex. ESX/VMWare, planned EOL) now with baremetal Win2012 DataCenter, every machine has the same HW and SW (inc policy).
I want to create two clusters (MS SQL), for testing purposes. I can see three possible configurations:
Create two separate Failover Cluster: 3 nodes for primary environment, 2 nodes for secondary environment
Create two separate Failover Cluster: 2 nodes for primary, 2 nodes for secondary, last (switched off) as a substitute
Create one Failover Cluster (5 nodes / 4+1) and create one/two virtual(s) for primary/secondary environment
Would it be better to separate the environment to two farm or to create one farm with virtualization, my intended use is only MS SQL Clustering
