Hey Eugen,
AFAIK the Ceph NVMe-oF Gateway superseded the iSCSI one: it's actively maintained, more performant, scalable, secure and better integrated with the Ceph management & observability framework.
The iscsi-gw has lacked a maintainer for quite a while. If someone really really needs to run iSCSI, they might check out https://github.com/frednass/ceph_petasan
I'm curious: what's the target platform/use case for iSCSI that NVMe/TCP cannot fulfill?
Clients that can't talk NVMe/TCP? E.g. some BIOS implementations? Certain VMware releases?
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?
I don't *think* that's the case, though I'd be curious re the use-case for the protocol backed by slow media.
Handing out iSCSI devices sounds useful as backing storage for VMs (and some can even boot off it).
RBD through libvirt is an all-around better solution for that. Fewer moving parts, less overhead, lower resource utilization on the Ceph side.
