The admin next to me, who looks after our VMWare infrastructure, tells me that you can improve performance for I/O intensive functions by presenting the storage as a raw device, rather than through the datastore. Certainly, we run some busy databases and even an exchange server on virtual machines, and the only complaints raised were when they were accidentaly put on a datastore and the other VMs using it suffered.
