This is actually what I want to know as well.

I know the different technologies (AOE / iSCSI / NFS / etc) all have
different pro's & cons, but how do I actually use them optimally?

AOE seems to have less network overhead since it runs on the network
layer and not on TCP or IP, so this is probably a good option to go
for. I'm thinking of setting up a few NAS servers with CentOS + CLVM,
or maybe even a few NAS servers with Gluster and then export the file
systems from them to the XEN servers.

But, do I export it to the dom0, or the domU's directly? That I don't know.

Kind Regards
