they are different things. i am planning on setting up two servers with 
a lot of storage space on then with drbd sync'ing the data between the 
two. then run one or more iscsi targets on top of the drbd volume that 
multiple iscsi initiators will connect to. i'm also going to use either 
heartbeat or pacemaker to set up automatic failover of the drbd roles 
and the iscsi targets. this should give me a somewhat cheap alternative 
to buying san.

there is a brief overview. the current problem though is that drbd is 
having trouble completing a sync over the 10 gig interfaces.
