"Dual Single Ended Ultra Wide SCSI card" would mean it has two SCSI
channels (and presumably) two external ports. I have used several Sun
dual-channel cards though I don't remember their exact part numbers.
They usually use the same chips and drivers as their single-port
counter-parts except that the dual channel cards come with VHDCI ports.
Sun also usually provides cables with VHDCI and 68-pin connectors with
those cards.
