We use iSCSI disks to add disks/volumes for our (virtual) machines. I woul dlike to move to the appliance verison, but currently, it is not possible to add iSCSI disks to an appliance instead of vmdk/xen disks.

For us, and I think for any customer using iSCSI, this would be a huge advantage, not just for SZCM, but also for other appliances like Filr
