As someone who is running pure spinning rust Ceph clusters, I assume the
NVMe-oF gateway requires actual NVMe devices to be used for backing, given
that the docs mention sending NMVe commands to targets, correct?
Handing out iSCSI devices sounds useful as backing storage for VMs
(and some can even boot off it).
Kind regards,
Alex.
