SQL with no downtime

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.

For what you want you need clustered sql instances running on clustered storage pools. 1# removes the sql server dependency and #2 removes the storage dependency.  None of this comes free.. Double the storage costs (including the subsystem) plus double the server costs.

I found this

SQL Server 2012 AlwaysOn Availability Groups –  an AlwaysOn Availability Group is created between several standalone SQL Server instances. At least you need 2 different SQL Server instances. All instances that participating in an AlwaysOn Availability Group don’t need any Shared Storage

Would this work?

I have lots of space and servers so that is no cost. Adding shared storage is a big cost.

This should work as the database would kept in multiple instances and there would be no need to update the connection string on failover as this is taken care of as part of the Always on Availability Groups.

You may want to look into the licensing cost, as that may be a determining factor.

Good point. Need an expensive license.

The group will work but will cost too much
