Using
the
Adaptec
HostRAID
configuration
programs
Use
the
Adaptec
RAID
Configuration
Utility
programs
and
SAS/SATA
Configuration
Utility
to
add
RAID
level-0
and
level-1
functionality
to
the
integrated
Serial
ATA
(SATA)
controller
(simple-swap
models)
or
the
SAS/SATA
controller
(hot-swap
models).
RAID
level-0
(striping)
causes
the
drives
to
be
seen
as
a
single
volume,
and
improves
performance.
RAID
level-1
(mirroring)
causes
the
contents
of
one
drive
to
be
copied
to
the
other
drive
to
create
redundancy,
so
that
if
one
drive
fails,
no
data
is
lost.
Be
sure
to
use
these
programs
as
described
in
this
document.
Use
these
programs
to
perform
the
following
tasks:
v
Configure
a
redundant
array
of
independent
disks
(RAID)
array
v
View
or
change
the
RAID
configuration
and
associated
devices
When
you
are
using
the
Adaptec
RAID
Configuration
Utility
programs
and
SAS/SATA
Configuration
Utility
program
to
configure
and
manage
arrays,
consider
the
following
information:
v
The
SAS/SATA
controller
with
integrated
RAID
(hot-swap
models)
or
the
integrated
SATA
controller
(simple-swap
models)
with
integrated
RAID
support
RAID
level-0
and
level-1.
An
optional
ServeRAID
controller
provides
additional
RAID
levels.
v
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
(adapter)
in
the
server,
use
the
method
that
is
described
in
the
instructions
that
come
with
the
adapter
to
view
or
change
SAS
settings
for
attached
devices.
Using
the
Adaptec
RAID
Configuration
Utility
programs
(for
Serial
ATA
HostRAID)
Use
the
Array
Configuration
Utility,
in
the
Adaptec
RAID
Configuration
Utility
programs,
to
add
RAID
level-0
and
level-1
functionality
to
the
integrated
SATA
controller
(simple-swap
models).
This
utility
is
part
of
the
BIOS.
Note:
To
add
RAID
functionality
to
a
hot-swap
SATA
model,
see
“Using
the
SAS/SATA
Configuration
Utility
program
(for
SAS/SATA
HostRAID)”
on
page
44.
For
additional
information
about
using
the
Adaptec
RAID
Configuration
Utility
programs,
see
the
documentation
on
the
IBM
ServeRAID-8e
(Adaptec
HostRAID)
Support
CD.
If
this
CD
did
not
come
with
the
server,
you
can
download
it
from
http://www.ibm.com/support/.
The
integrated
SATA
RAID
feature
(SATA
HostRAID)
comes
disabled
by
default.
You
must
enable
it
and
install
the
device
drivers
before
you
can
use
it.
The
SATA
RAID
feature
configuration
utilities,
device
drivers,
and
information
are
available
on
the
ServeRAID-8e
(Adaptec
