operation
of
the
RAID
controller
Consider
the
following
information
when
you
use
the
IBM
ServeRAID
Configuration
Utility
program
or
ServeRAID
Manager
to
configure
and
manage
arrays:
v
The
ServeRAID-8s
SAS
controller
supports
RAID
levels
0,
1,
1E,
5.
6,
10,
50,
and
60.
v
Servers
that
come
with
twelve
2.5-inch
hot-swap
SAS
drives
also
come
with
two
ServeRAID
SAS
controllers;
a
ServeRAID-8k
controller
in
the
ServeRAID
connector
on
the
system
board
and
a
ServeRAID-8s
controller
in
PCI
Express
slot
2.
The
ServeRAID-8k
controller
supports
the
first
eight
hard
disk
drives,
and
the
ServeRAID-8s
controller
supports
the
four
remaining
hard
disk
drives.
v
The
integrated
ServeRAID-8k
controller
is
disabled
when
BIOS
detects
an
optional
ServeRAID-10is
has
been
installed
in
the
server.
v
When
you
configure
the
12
hard
disk
drives,
you
may
configure
the
first
eight
drives
into
an
array
that
is
attached
to
the
ServeRAID-8k
and
the
remaining
four
drives
into
an
array
that
is
attached
to
the
ServeRAID-8s.
v
Hard
disk
drive
capacities
affect
how
you
create
arrays.
The
drives
in
an
array
can
have
different
capacities,
but
the
ServeRAID
controllers
treat
them
as
if
they
all
have
the
capacity
of
the
smallest
hard
disk
drive.
v
To
help
ensure
signal
quality,
do
not
use
drives
with
different
speeds
and
data
rates.
v
Do
not
include
SAS
and
SATA
drives
in
the
same
array.
v
To
update
the
firmware
and
BIOS
code
for
an
optional
ServeRAID
controller
or
controllers,
you
must
use
the
IBM
ServeRAID
Support
CD
that
comes
with
the
ServeRAID
option.
