Can one use a spare SCSI or FC controller as if it were a target? Even if the hardware is capable, I don't see what you describe as a ZFS thing really; it isn't for iSCSI, except that ZFS supports a shareiscsi option (and property?) by "knowing" how to tell the iSCSI server to do the right thing. That is, there would have to be something like an iSCSI server except that it "listened" on an otherwise unused SCSI or FC interface. I think that would require not just the daemon but probably new driver facilities as well. Given that one can run IP over FC, it seems to me that in principle it ought to be possible, at least for FC. Not so sure about SCSI. Also not sure about performance. I suspect even high-end SAN controllers have a bit more latency than the underlying drives. And this is a general-purpose OS we're talking about doing this to; I don't know that it would be acceptably close, or as robust (depending on the hardware) as a high-end FC SAN, although it might be possible to be a good deal cheaper.
