I'm aware of this - and that is the point I was getting across.
As with iSCSI initiator I COULD attach as local disk and direct connect and take advantage of near full network speed with smaller overhead.
In my opinion. There would be more overhead
ISCSI LUN attached to Xen Hypervisor > VM > attached as local disk. Unless pass-through?
Furthermore. The issue stands.
With the primary data being on the Citrix Xen Server as local disk (iSCSI LUN storage). if I was to migrate to an NFS Stor. Mounted to Xen Server.
I would attach as a NEW disk to that Virtual Machine. Mount it within Windows and format. Then I'll be stuck wit 'xcopy' the data & Permissions over to this new storage drive.
As this is an issue now, as the Citrix Xen server has storage ties to our original Synology 4-bay NAS.
I've been wanting to move ALL our LUN's and data to our newer larger Synology NAS. And then use the original 4-bay as a replication/ back-up
