Ultra 160 SCSI Interface
The Ultra 160 SCSI interface provides a low-voltage differential (LVD) mode running up to
160 MB/second and a single-ended (SE) mode running up to 40 MB/second.
N OTE : The host computer’s SCSI controller card may limit these speeds. To
achieve the best performance, make sure the SCSI controller card can
operate at 160 MB/second.
The tape drive automatically senses the SCSI bus mode and switches between LVD and SE
accordingly. Although the tape drive defaults to LVD, it switches to SE if the SCSI bus operates in SE
mode. For example, if the SCSI controller card is SE (or multimode set to SE), the tape drive
automatically switches to SE mode. Also, if any device on the SCSI bus is SE, the entire bus switches
to SE, including the tape drive.
