if i want to configure all the databases on a sql server instance for a failover capability, should i just go for SQL Server clustered instance rather than setting up always on? The additional investment ive to make for FCI will be using SAN disk instead of local disks. Am i correct in the assumption?
2nd question, Only advantage of using Always on over FCI will be saving money on SAN storage am i right here? is there any other consideration in going for Always on feature?
