SCSI LVD Tape Drives: LVD tape drives can be connected to any SCSI port on the Virtual
TapeServer server module that has not been reserved for use as a virtual drive. The Virtual
TapeServer server module uses a female VHDCI connector, so a cable with a male VHDCI is
required. Depending on the type of tape drive, that end of the cable probably uses a male
MD68 connector. Two drives can be daisy chained, and an LVD external terminator is required
on the last drive in the chain. SCSI cable length for a single tape drive is limited to 25 meters
(82 feet). SCSI cable length for two daisy-chained drives is limited to12.5 meters (41 feet).

SCSI HVD Tape Drives: A HVD SCSI tape drive connection must be routed through a Virtual
TapeServer SCSI interface conversion module to convert the LVD SCSI signal to HVD SCSI. A
6-foot male MD68 to male 68 VHDCI SCSI cable connects the Virtual TapeServer server
module to the Virtual TapeServer SCSI interface conversion module. Use a male MD68 to male
MD68 cable to connect the Virtual TapeServer SCSI interface conversion module to the HVD
tape drive. Up to two drives can be daisy chained subject to the maximum SCSI limitation of 75
foot total cable length. A HVD terminator is required on the last drive in the daisy chain.
