I am disappointed to report the $400+ 3Ware 9690SA SAS controller card is not a true HBA, capable of controlling an external HP StoargeWorks Ultrium 1760 SAS LTO4 drive. When i connected the card to the tape drive, with a SAS 8088 to 8088 cable, and boot the system, during the boot, the card's rom reports a SAS error. Booted to Linux 2.6.30-gentoo-r6 kernel, with loaded 3ware 9xxx SATA-RAID module (CONFIG_SCSI_3W_9XXX=y) the system sees the card, but the card does not show up in /proc/scsi/scsi. I am going to try the HP Smart Array Controller P212 256MB Cache (462834-B21) next.
