I agree with all of you ! ADSM must support SAN , asap. As an IBM BP, we compete
versus other products who support SAN. I have seen sea scape trends and 
directions,
but as always this is mainly for IBM SSA. We didn't get any trends and 
directions
for Network Appliance for example, which is very growing product. We asked IBM a
year ago when will the support NDMP protocol, but we didn't get any dates yet.

If some one have any ideas of what is going to be, I will be happy to know !
