Adaptec AHA-2940UW

Mark: Good

I can say definitively that Adaptec AHA-2940UW/2940U2W/2940AU/3940(UW[?])/29160/29160LP all work with Bootable JFS - which I've been booting with since September 2004, when the installed boot-volumes on HPFS were able to be converted to bootable-JFS. I used the narrow 2940AU (50-pin) via a PCB converter that converted 80-pin SCA or 68-pin regular LVD/SE to 50-pin SCSI2. All of the others ran/are running with 69-pin cables/connectors.

Lewis Rosenthal mentioned that SCSI-RAID on HP servers wouldn't boot JFS, but that's a different level of equipment - I think, unlike all of the above Adaptec HBAs which all support INT13 extensions, the HP/CPQ Server's HBA (brand unknown) did not support that feature, and that capability is required for JFS-booting on SCSI. You'll probably find that LSI also supports INT13X - I'm almost certain. My very good friend, the late Don Woodall in Michigan would definitely have been able to tell you about the LSI products as he had a bunch of them - and would have had them all running JFS-boot!
