Fabric
Access.
Allows
the
application
to
control

configuration.
Fabric
Manager.
A
feature
that
allows
the
storage
area
network
(SAN)
manager
to
monitor
key
fabric
and
switch
elements,
making
it
easy
to
quickly
identify
and
escalate
potential
problems.
It
monitors
each
element
for
out-of-boundary
values
or
counters
and
provides
notification
when
defined
boundaries
are
exceeded.
The
SAN
manager
can
configure
which
elements,
such
as
error,
status,
and
performance
counters,
are
monitored
within
a
switch.

over
links.
Can
be
used
to
connect
a
node
port
(N_port)
to
a
switch.
