Only shortcoming in Proxmox realm in the past was the very non enterprise iSCSI implementation (istgt) which was replaced by cltd, a very fine iSCSI implementation, but limited to 1024 LUNs per target in the past but according to your links has since increased. (By the time I was looking into to this I had numerous discussions with the developer about this issue and I promised to inform me personally when he removed the limitation - I haven't heard from him) > Solution derivated from Illumos are either overpriced, closed source > and scarcely used or abandoned (if not all at the same time). > This is where you I misinformed ;-) Illumos is truly FOSS an lives well. Commercially with SmartOS, but not closed source since all patches are sent upstream. The non-commercial branch of Illumos also lives well as OmniosCE and are well maintained by Andy and Tobias to mention a few (I have a small part as well ;-). I think you are thinking of Solaris as in Oracle Solaris which is definitely on the usual way to desintegration as all other stuff Larry gets his hands on. You should also remember that all ZFS development, apart from the black caves near Redwood City, is done in OpenZFS and all current implementations apart from Oracle uses the same source tree. > I think that It might be time to re-considering FreeBSD as a > potential stable solution to host iSCSI targets.

It should be rather easy to write such a plugin using the istgt code an replace the iSCSI part with cltd.
