SCSI Bus Differences

SCSI Bus Differences

A Small Computer Systems Interface (SCSI) bus is an IEEE standard bus for connecting your workstation to internal and external devices (SCSI devices) running at different speeds. There may be one device connected to the external SCSI port or several SCSI devices may be daisy chained together and connected to the external SCSI port. Examples of these SCSI devices are 4-mm DDS-format tape drives and hard disk drives.

There are two types of SCSI buses available with this workstation—an Ultra Narrow Single-Ended SCSI bus (NSE SCSI), and an Ultra2 Wide Low-Voltage Differential SCSI bus (LVD SCSI). The following table shows the specification differences between these SCSI buses.

CAUTIONCurrently Hewlett-Packard does not support mixing Ultra Narrow Single-Ended and Ultra2 Wide Low-Voltage Differential devices on any one bus type.
