You could get an IFL for the same price and use any left-over cycles for Other Work. But I think I'd rather see the System z FCP adapter support being a *target* WWPN+LUN. That would open up the moral equivalent of SAN Volume Controller (or maybe SVC itself!) on System z. The targeted device driver could emulate any kind of SCSI device it wanted to, hiding the backend implementation, just as SVC does. You'd get the benefits of emulation without the overhead of iSCSI.
