The only technical "advantage" of DSSI was that it better matched some of DEC's other proprietary storage standards, thus enhancing vendor lock-in and profitability. If you were another company trying to decide whether to use SCSI or DSSI in your products, even if licensing and related cost weren't at issue, the _only_ reason to use DSSI would be to interoperate with DEC. I was a fan of DEC, but they did plenty of things for vendor lock-in rather than technical reasons.
