sd is the older scsi-disk driver, ssd is the new scsi-disk driver (part of the leadville driver package) that allowed for more than 256 luns per target...
We've had systems that used the sd drivers until we upgraded to newer, sun provided drivers for qlogic / emulex cards, which then were using the ssd driver. Both handle scsi (or emulated scsi from the different device driver layers) devices. -- This message posted from opensolaris.org _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
