Assign
the
appropriate
IP
address
to
the
management
and
data
ports
either
statically
or
using
DHCP.
If
you
are
setting
the
MTU
to
something
other
than
1500,
ensure
that
your
switch
configuration,
as
well
as
all
the
hosts
on
the
network,
support
larger
MTU
settings.
The
Verde
master
node
can
support
jumbo
frames
(MTU=9000),
but
all
switches
and
hosts
on
the
network
must
be
configured
to
support
jumbo
frames
if
this
is
selected,
or
performance
might
be
degraded.
Link Aggregation Notes
Switches
use
different
methods
of
routing
traffic
from
hosts
to
NAS
servers.
There
are
also
many
different
network
configurations
to
move
data
from
hosts
to
NAS
servers.
For
example,
some
Cisco
switches
route
traffic
based
on
the
MAC
address
and
the
IP
address.
The
Verde
array
presents
only
one
MAC
address
and
one
IP
address
when
the
data
ports
are
aggregated
via
DHCP.
If
static
link
aggregation
is
chosen,
the
Verde
array
presents
only
one
MAC
address,
but
can
have
up
to
16
IP
addresses
aliased
to
the
MAC
address.
It
is
up
to
the
switch
to
rotate
data
transfers
among
the
physical
ports
on
the
Verde
array
in
order
to
achieve
the
highest
throughput
possible.
