The theory is that iSCSI does nothing like this; especially not the reordering part, that would be a definite violation of the standard. And I am pretty sure that ACKing a write which wasn't permanently committed (either to disk or NVRAM etc) would violate the standard pretty badly too and make the thing behave just like IDE ;-) So, where did you get the ideas that iSCSI does all these nasty things? ;-) The "longer time than physical disk" depends on your connectivity; with GigE, this should be barely noticeable, if at all. iSCSI isn't meant for long-distance, high latency, low bandwidth links I am pretty sure. What are you trying to do? As a hand-waving guess, it sounds like you want to store your data far away for disaster recovery purposes? In this case, I would suggest doing either remote backups or checking out DRBD (on http://www.linbit.com/), a network mirroring block device.
