Since I had initiated a discussion about ADSM alternatives, I guess I
should be the one to point out that FDR/Upstream/SOS can xfer data at
ESCON speeds (17Mbytes) also!  You have to have both platforms attached
to a EMC2 Symmetrix box (though you don't have to have the file that you
are backing-up physically on the Symmetrix box).
