Hi Todd,

Thnkz for the answer...
In short what I understood from it...each active iscsi server has it's own storage, in this case a fc volume. And each active iscsi server needs it's own standby server to replicate to...is this correct ?
The replicating part confused me a little because there's no need to replicate data from the volumes...but I guess you mean the configuration is replicated...right ?

I didn't really understand what you mean by a DDS server in front of two iscsi r3 servers...it seems to me an extra layer is added that doesnt really give me more high availability....but I guess that's my way of thinking messing this up...could you explain that ?

As for the Xen thing...it should work...but were waiting for Xensource to come out with their next version that supports iSCSI in a decent way....now they import large iscsi volumes and use lvm2 on top of that locally to create volumes for the xen guests...
But we tested some with the open source hypervisor and open-iscsi and it worked like a charm...
Hopefully Xensource and Open-E soon release new versions so Open-E has HA support and Xensource supports a volume for each Guest...sometimes the world can be really great

As I'm from the Netherlands I don't know what area I'm in for pre sales questions...
Anyway...lots of thanks for your answers...
