SCSI commands and for initiating tape drive operations. In the case of the SBB the connection to the SCSI bus is made through the StorageWorks Expan- sion Storage Pedestal, as discussed in Chapter 2. For the Tabletop device, the connection to the SCSI bus must be made through an appropriate cable, depending on the type of host adapter that is used and/or the desired physical length of cable (See Chapter 3). -
