I have to order a SCSI HBA for the v440 server. I have come up with two part
numbers:
Part#: 501-5656 Single Ended Ultra Wide SCSI card
Part#: 375-0005 Dual Single Ended Ultra Wide SCSI card

What is the difference between them?

Does Dul Ended (375-005) means that it has two SCSI ports?

"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.
