Jose Barreto, MS storage whiz, has written a pretty complete looking article on getting Hyper-V up and running with iSCSI. If you’ve seen a Hyper-V cluster demonstration in Ireland then there’s a very good change that it was this sort of technology that you saw. MS Ireland IT Pro, Dave Northey, uses iSCSI and he’s normally the guy talking about this stuff in Ireland. Dave put up a video on his blog on how to get this stuff up and running.
