I am planning to build a new AG setup in my QA environment with the following configuration. What I want to know is, can I have 2 heartbeat networks between the nodes for redundancy also, how many NIC's can be used in this scenario? The whole setup will be virtualized.
On both the nodes :
One public network for client connectivity
2 heartbeat networks for redundancy
One network for Database Mirroring
For this setup, I am assuming these are the IP addresses which are required
- 1 static IP for each of the node
- 1 static IP for the WSFC
- 1 static IP for the AG listner
- 4 static IP's for creating the 2 heartbeat networks
The nodes will be standalone instances with independent storage. The end result I am looking for is to create redundancy for the heartbeat network. Can I create one of it using a different IP range or from a different subnet? The nodes will be built at the Atlanta Datacenter where I am working right now. Please advice.
