2.6 SCSI Signal Converters
If you are using a standalone storage shelf with a single-ended SCSI
interface in your cluster configuration, you must connect it to a SCSI signal
converter. SCSI signal converters convert wide, differential SCSI to narrow
or wide, single-ended SCSI and vice versa. Some signal converters are
standalone desktop units and some are StorageWorks building blocks (SBBs)
that you install in storage shelves disk slots.
