Virtual TapeServer 6.04.01 Installation Guide

Cabling and Connecting VTS | 27
SCSI LVD
LVD tape drives can be connected to any SCSI port on the VTS server module that has not
been reserved for use as a virtual tape drive. The VTS 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 12 meters (39 feet). If multiple devices are daisy-chained
on the bus, add the internal and external cable lengths between each device.
HVD SCSI
An HVD SCSI tape drive connection must be routed through a VTS SCSI converter to convert
the LVD SCSI signal to HVD SCSI. A 6-foot male MD68 to male 68 VHDCI SCSI cable
connects the VTS server module to the VTS SCSI converter. Use a male MD68 to male MD68
cable to connect the SCSI converter to the HVD tape drive. Up to two drives can be daisy
chained subject to the maximum SCSI limitation of 82 foot total cable length. An HVD
terminator is required on the last drive in the daisy chain.
Connecting to the LAN, SAN, and power
The following sections describe how to connect VTS to the network and power.
Connecting to a LAN
VTS is equipped with two standard 10Mbps/100Mbps/1Gbps Ethernet ports. Connect
Ethernet port 1 for normal connectivity and port 2 for Instant DR and AutoCopy functionality.
Port 1 corresponds to Eth0 in Linux, and Port 2 corresponds to Eth1.
