I am interested in your powerpoint...I just didn't get the point you wanted to make with the dds setup...
And I still don't see why replicating the volume data as it is on shared storage...I got the feeling you want to give the standby server it's own FC volume so all data will be available twice on the FC array...When I import a FC volume on a linux box and create volumes on it using LVM2 I can have any other linux box import the same FC volume and it sees all LVM2 created volumes...So only thing left to replicate would be target config, snapshot schedules and all other sorts of config files...
I guess it should also be possible when I have a single Open-E box using a FC backend and it completely dies to get my data back on line without anything missing ? A simple config backup of the Open-E box should do the trick (if possible)
I would be happy to post some stuff in the vmware section (rename to virtualisation software ??? ) As soon as I have a beta for the next version I will post some howto's...
For know linux users that do not have serious experience with iscsi can use Kiscsiadm a small desktop tool to makes iscsi initiator management very easy. http://sourceforge.net/projects/kiscsiadm/
