Does DAG require double the amount of storage.  for example lets say I have 2 node DAG and they are running Mailbox server roles, Do I need to make 2 database copies 1 for each node and does this require two seperate volumes from our san.  100 gb database will it require 2 100gb volumes on san or can the dag used shared storage and when it failsover the second node pickups the database.

You cannot create DAG on same server. You need minimum 2 node with exactly same hardware structure. So, if your DB on Active server is 100 GB then you need same size on server 2 also.

Whenever you are planning to deploy DAG. You need below, in order to have maximum high Availability

Server resilency (For that you need to keep them in two different server, even if you are using VMware or Hyper. Never keep host in same server)
Disk resilency
Site resilency (Keep on more server in another site)
