Datasync mode
In DataSync mode, reads and writes are done to memory only. The
disk remains offline during normal operation. If power loss occurs
and the shutdown timer reaches zero, or the user requests a
shutdown, the system takes the Fibre Channel interfaces offline
and synchronizes all data to the internal hard drive.
Volatile mode (optional)
This operational mode disables the backup functionality for the LUN
making it completely volatile. In the case of system shutdown or
failure, all data stored in the selected LUN will be lost intentionally.
