LSI 1030/1035 U320 (fusion) controllers have simple raid0/raid1 support Adaptec and LSI still have some u160 or even u320 controllers in the aacraid/ megaraid series afaik, the present the same interface to the OS for parallel scsi/sata/sas so it's a bit hard to say for me which is the most recent parallel scsi one. The old Mylex controllers supported by drivers/block/DAC960.c support up to u160, and u320 with an IBM-branded controller which probably isn't sold separately from IBM Equipment and probably not at all anymore. The IBM i/pSeries integrated RAID supports up to U320 (drivers/scsi/ipr.c), but you don't get it without an i/pSeries system. There's Intel Branded, Adaptec manufactured RAID cards that support U160 SCSI, they're supported by drivers/scsi/gdth.c - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
