File cluster 2012

Hello,

I have a few questions. 

• 1) I am looking to set a 2 nodes file cluster server using Windows 2012.  Technically, would I be able to setup an environment that if one node goes down, the remaining node automatically to take over?
• 2) We are using AWS (amazon storage) for our volume via iSCSI connection.  For the two nodes, do I have to add the same volume to each server so each server one see the same volume? Just making sure.
• 3) I want to enable deduplication on the volume, so on each server, I have to enable the same volume?

Thanks,

TT
