you don't have to reconfigure engine to create iscsi pool.
you can create multiple pools, the only limitation is that you will need
a host for the each of the DCs.
but you can move one host from one DC to another...
so if you have 2 hosts just create a new DC and move one of the hosts
there.
I think that the direct lun is only for iscsi and fiber but I can give
you a 100% certainty answer on Monday.
I don't think its supported for NFS... I can check for you on Monday for
sure.
