We have a recently installed MS SQL 2012 cluster.
- How many more instances can be added to it?
- Does each instance requires a separate SQL license?
- How many separate SAN drives will we need for each instance? Currently we have: 1. database 2. log 3. TempDB 4. Backup. Perhaps Backup drive can remain same, but what about TempDB drive? It seems, minimum two new SAN disks be needed?
