Narrow or wide SCSI
The Exabyte X200 library supports wide SCSI only. The tape
drives installed in the library also support wide SCSI only.
If you plan to connect the wide HVD library to a narrow HVD
SCSI bus, you need to use SCSI cable adapters. See
HVD adapter specifications.
Note: Since LVD is available in wide only, LVD adapters are not
Fast SCSI
The library supports fast SCSI, which does not require any special
cabling or configuration. In addition, an LVD SCSI interface
allows the library and tape drives to be placed on the same bus as
Ultra and Ultra2 SCSI devices without slowing the performance
of these devices. However, proper cable lengths, stub length, and
termination are more important on a fast SCSI bus than on a
regular SCSI bus.

SCSI cabling

When connecting the library and other devices on the SCSI bus,
follow these guidelines for SCSI cabling:

available.
Total Length. Make sure the total length of all internal and
external cables on the LVD SCSI bus does not exceed 39 feet
(12.0 meters). If your LVD SCSI bus is a point-to-point
connection (target and initiator only) or if the library SCSI bus
is HVD, make sure the total length does not exceed 82 feet
(12 meters).
