with
integrated
SCSI
RAID
(SCSI
models)
and
the

controller
(SATA
models)
with
integrated
SATA

support
RAID
levels

provides
additional
RAID
levels.
v
You
cannot
use
the

Hard
disk
drive
capacities
affect
how
you
create
arrays.
Drives
in
an
array
can
have
different
capacities,
but
the
RAID
controller
treats
them
as
if
they
all
have
the
capacity
of
the
smallest
hard
disk
drive.
v
To
help
ensure
signal
quality,
do
not
mix
drives
with
different
speeds
and
data
rates.
v
To
update
the
firmware
and
BIOS
code
for
an
optional
ServeRAID
controller,
you
must
use
the
IBM
ServeRAID
Support
CD
that
comes
with
the
ServeRAID
option.
v
If
you
install
a
different
type
of
RAID
controller
in
your
server,
use
the
configuration
method
described
in
the
instructions
that
come
with
that
RAID
controller
to
view
or
change
SCSI
settings
for
attached
devices.
