The Fibre Channel tape drive can be connected directly to the server with a host bus adapter (HBA) or
through a storage area network (SAN).
NOTE
Use
an
appropriate
HBA
for
your
tape
drive
due
to
performance
considerations.
A
lower
throughput
HBA
might
result
in
performance
degradation
when
backing
up
highly
compressible
data
to
a
higher
throughput
tape
drive.
In
a
SAN
installation,
all
switches
between
the
host
and
the
library
must
be
of
the
appropriate
type.
A
lower
throughput
switch
in
the
path
may
result
in
performance
degradation.
Configure
zoning
so
only
the
backup
servers
may
access
the
library.
