operation

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

CD

that

comes
