Use A3312A on Intel H/W

Has anybody found a controller that will work on an Intel platform that will talk to a A3312A disk enclosure (9.1GB FWD drives)?

Sure, you need an Adaptec AHA-2944UW. The fundamental problem is that almost everything these days is Low Voltage Differential (LVD) and you need High Voltage Differential (HVD) SCSI.

If it ain't broke, I can fix that.

Kim,
hard drives supplied by HP for Jamaica HASS have HP-developed firmware (HPxx), and this firmware is designed to work with HP-UX hosts.

Getting conflicting info here... Either I CAN use the box (drives and all) with the HV controller, or I can't.

It is true that HP installs vendor specific firmware on the drives but that is so that the UNIX boxes will recognize the SCSI ID strings. The drives will still respond to a device inquiry. Most PC's don't have a clue as to what kind of drive they are connected to; they do an inquiry to find out. Your fundamental problem is HVD; fix that and all will be well. If you want further proof, the AutoRAID 12H's can be connected to both UNIX boxes and Windows servers - with the same firmware. I've even connected them to both an HP-UX box and an NT box at the same time (and on the same bus). That works just fine as long as one HBA is left at SCSI ID 7 and the other is changed to 6. Of course, in that case, an individual LUN should only be accessed by one of the boxes.
