I have a Server 2008 r2 machine running SQL 2008. I have one database that I want as much up time as possible. I do not have any shared storage. I have 4 servers that are running ESXi 5.1.
Is it possible to have more SQL up time (HA) without a cluster?
Also when people use a cluster with shared storage isn't the shared storage a major vulnerability? So when the SAN goes down it takes down every single server? Right now when a server goes down only 25% of services are affected.
