DSSI: What was it like?

DEC's proprietary DSSI interface: Can anyone give me some idea of why DEC came up with it, what benefits it offered over, say, SCSI, and whether it was entirely proprietary or related to something like IPI? For that matter, what the heck did DSSI abbreviate? My guess: Distributed Storage Subsystem Interface. Web sites, FAQs, or commentary are all welcome as this is pure curiousity on my part. Thanks much. -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- Bruce Lane, Owner and head honcho, Blue Feather Technologies http://www.bluefeathertech.com // E-mail: kyrrin(a)bluefeathertech.com Amateur Radio: WD6EOS since Dec.
