Description

The multi-drop SCSI bus has an inherent problem as drives are added to the SCSI bus the impedance of the bus drops. Some Ultra160 and Ultra320 systems may not operate at rated speed because of errors or the SCSI domain validation (SDV) adjusting the speed down to a level that will operate.
