Like most other current SCSI drives, the Savvio supports the SCAM protocol (SCSI Configured Automatically), which automatically assigns a suitable drive ID. That's not a bad feature, as jumpers would not have been a good idea anyway on the small and tightly packed board. There would also be the huge bother of removing the drive from the casing before being able to change a jumper.
