Hi

A question:

What if I want to have a storage cache enabled or disabled according to my 
preferences for use with multiple virtual disks?

For example, in a same VM:
- The first disk is for the OS (cache isn't necessary, a bit of write is
performed)
- The second disk is for the data base (cache will be very important)
- The third disk is for the log of the data base (cache will be very
important)
- The fourth disk is for backups of data base (cache isn't necessary)

Best regards
Cesar
