I have setup Failover Cluster Instance on 2 nodes with Windows Server 2008 and SQL Server 2012 running on a SAN storage with "Node and Disk based Quorum", DTC and public and Private IP communication.
Now I want to setup multi-subnet cluster by adding another two nodes and a SAN storage from different subnet.
I have following questions in mind for which I am looking for your expert help:-
- Do we need to enable communication between public IP of site1 servers and public IP of site2 servers and how?
- How our existing cluster in site1 can be stretched up-to site2 so that DC2 will also have Active-Passive architecture when failover to site2?
- How the Quorum will work in Node and Disk Majority mode in site2?
- How the Private IP communication will work when SQL Server 2012 Cluster failover to site2?
- What are the components we will replicate from site1 to site2 using SAN replication? Will quorum will also get replicated or we should exclude quorum from replication?
I am new in multi-subnet cluster setup and looking for your urgent help for my setup.
