failover

We have a VM running SQL Server on a 6 node cluster of blades. The VM's data files are stored a SAN attached using a direct iSCSI connection.

As this SQL server will be running a number of important databases we're debating whether we should be clustering the SQL Server or will the fact that the VM is running in the cluster itself sufficient to give us high availability. I'm used to running SQL clusters when dealing with physical servers but I'm a bit sketchy on what is best practice when all the servers are just VMs sat on Hyper V.

If a blade running the VM fails I presume the VM will be started up on another load. I'm guessing the only benefit that adding a SQL cluster to the setup will give us it that the recovery time after a failure will be a little quicker? Are there any other benefits?
