Hello,

I've no direct experience, but i suppose that both modes are available, if
they are supported by a standard RHEL machine. In particular the
"Independent mode" should be like said before: you'll see the storage as FC
lun. In the other mode i think is a standard iSCSI setup, but requires the
driver for taking advantage of the offloading.
