v

The

optional

ServeRAID-10is

SAS

controller

that

you

can

install

in

your

server,

supports

RAID

levels

0,

1,

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

supports

the

four

remaining

hard

disk

drives.

v

The

integrated

ServeRAID-8k

controller

is

disabled

when

BIOS

detects

an

optional

ServeRAID-10is

controller

in

the

server.

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

in

the

array.

v

You

can

set

up

a

mirror

after

the

operating

system

is

installed

on

the

primary

drive.

You

must

make

sure

that

the

primary

drive

has

the

lower

ID

(for

example,

0).

v

To

update

the

firmware

and

BIOS

code

for

the

ServeRAID-8k

SAS

Controller,

you

must

use

the

IBM

ServeRAID

Support

CD

that

comes

with

the

server.

v

If

you

install

a

different

type

of

RAID

controller,

see

the

documentation

that

comes

with

the

controller

for

information

about

viewing

and

changing

SAS

settings

for

attached

devices.
