SCSI Cable Length

The maximum combined length for a string of SCSI cables is 6 meters for non-differential cables. For differential SCSI cables, the maximum is 25 meters. To calculate the total length of a SCSI string, include external cables, internal cables, and printed traces. Table C-3 lists measurements for Enterprise servers.
