Since some are using EMC DASD, and it appears that you are looking for a
centralized backup product (and assuming that you have a mainframe??),
another option to review is the FDR/Upstream/SOS product. The product uses
the EMC DASD as a conduit from OpenSystem to mainframe at SCSI/ESCON speeds
without clogging the network. And with the EMC Fibre Channel connects, it's
worth consideration!!
