opensource wide area san?

[Stephen]

We are useing an openfiler server here and it has been running great.

right now it is hosting several iSCSI connections to our servers
however we need to replicate data on one of the iSCSI volumes between
2 sites.

internally using DRBD/heartbeat comes to mind as a new but no brainer
solution. however these servers need to live in 2 different states
(and eventually maybe 3-4 locations)

generally it would seem that rsync would be better however it is a
file level replication and seems that it would not be able to
replicate the iSCSI volume which is block level...

can DRBD/heartbeat sync across a t-1 or pair of bonded t-1's? or will
it eat the pipe?
