Subject: Multi-host SCSI? (CMD claims DSSI equivalence)

We are interested in buying SCSI controllers to go in a dual-host 3400. CMD
claim their CQD-240 controller is equivalent to DSSI in that it lets both CPUs
have direct connections to SCSI disks.

I am a bit concerned about VMS and VAXcluster software support for this
configuration. To my understanding VMS does not support SCSI as a cluster
interconnect. The only interconnects are CI, NI and DSSI. So how can CMD do it?

Is there anyone out there using these controllers in a multi-host environment,
as opposed to a single CPU disk and tape controller?
