i'm beginner in netapp, I wanted some advice from those who have more experience.
I have fas 2520 dual controller ,data ontap 8.3, 12 hard disk 600gb sas. I connect two host vmware 5.5 to manage some Virtual machine.
I'm confused, it is better to start 7-mode o cluster mode?
The goal, to get continuity of service for V.M. If a controller fails the V.M must function.
The goal, use more space as possible, of 7,2tb least min 2tb available for data.
any suggestion is appreciated

ontap 8.3 does not exist for 7 mode, only cDOT
the latest release for 7 mode is 8.2.3. 7 mode is no longer being developed so for that reason alone you should install cDOT
with ontap 8.3 you can take advantage of ADP which will give you more usable capacity than 8.2

If the system ships to you with 8.3, it should have provisioned the root aggregates for the nodes using ADP already. If you purchased the system before 8.3 went GA, then you'll have to take a few extra steps to enable this great feature and save a ton of capacity on these smaller systems. Here's some instructions on how to do this:
Keep in mind it will use the disks in the onboard shelf for this, so if you have a hybrid configuration (like mine with 4xSSD + 20xSAS), you probably want to pull the SSDs out during the procedure then insert them and provision your FlashPool separately once your cluster is setup.
