Follow these guidelines when you place the boot disk of a virtual machine on a SAN-based VMFS volume:

• Consider the best practices for boot-from-SAN that Microsoft publishes in the following knowledge base article: http://support.microsoft.com/kb/305547/en-us.
• Test clustered configurations in different failover scenarios before you put them into production environments.
