1

 

or

 

2,

 

or

 

both,

 

before

 

the

 

integrated

 

Ethernet

 

controllers

 

on

 

each

 

blade

 

server

 

system

 

board

 

can

 

be

 

used.

 

The

 

Ethernet

 

controllers

 

are

 

integrated

 

on

 

each

 

blade

 

server

 

system

 

board.

 

The

 

Ethernet

 

controllers

 

provide

 

1-Gbps

 

full-duplex

 

capability

 

only,

 

which

 

enables

 

simultaneous

 

transmission

 

and

 

reception

 

of

 

data

 

to

 

the

 

external

 

ports

 

on

 

the

 

Ethernet

 

switches.

 

You

 

do

 

not

 

need

 

to

 

set

 

any

 

jumpers

 

or

 

configure

 

the

 

controller

 

for

 

the

 

blade

 

server

 

operating

 

system.

 

However,

 

you

 

must

 

install

 

a

 

device

 

driver

 

on

 

the

 

blade

 

server

 

to

 

enable

 

the

 

blade

 

server

 

operating

 

system

 

to

 

address

 

the

 

Ethernet

 

controller.

 

For

 

blade

 

server

 

device

 

drivers

 

and

 

information

 

about

 

configuring

 

the

 

Ethernet

 

controllers,

 

see

 

the

 

Ethernet

 

software

 

CD

 

that

 

comes

 

with

 

your

 

blade

 

server.

 

 

 

 

 

Your

 

networking

 

administrator

 

should

 

assist

 

in

 

the

 

configuration

 

of

 

the

 

network

 

infrastructure

 

before

 

you

 

connect

 

the

 

BladeCenter

 

T

 

unit

 

to

 

a

 

LAN

 

switch

 

or

 

similar

 

network

 

device.

 

This

 

section

 

provides

 

additional

 

guidelines

 

that

 

might

 

be

 

useful

 

in

 

setting

 

up

 

your

 

system.

and

Each

 

blade

 

server

 

has

 

two

 

independent

 

Ethernet

 

controllers,

 

each

 

with

 

its

 

own

 

MAC

 

address

 

and

 

a

 

dedicated

 

1

 

Gbps

 

link

 

to

 

one

 

of

 

the

 

switch

 

modules

 

in

 

I/O

 

module

 

bays

and

and

in

 

the

 

illustration).

 

In

 

this

 

configuration

 

(the

 

default),

 

the

 

blade

 

servers

 

share

 

access

 

to

 

four

 

external

 

ports

 

on

 

each

 

switch.

 

There

 

is

 

no

 

internal

 

data

 

path

 

between

 

the

 

two

 

switches

 

within

 

the

 

BladeCenter

 

T

 

unit;

 

an

 

external

 

network

 

device

 

is

 

required

 

for

 

data

 

packets

 

to

 

flow

 

from

 

one

 

internal

 

switch

 

to

 

the

 

other.

 

The

 

management

 

module

 

has

 

a

 

separate

 

internal

 

100

 

Mbps

 

link

 

to

 

each

 

switch.

 

These

 

links

 

are

 

for

 

internal

 

management

 

and

 

control

 

only.

 

No

 

data

 

packets

 

are

 

allowed

 

to

 

flow

 

from

 

application

 

programs

 

on

 

the

 

blade

 

servers

 

to

 

the

 

management

 

module

 

over

 

this

 

path.

 

A

 

separate,

 

nonswitched

 

path

 

(not

 

shown)

 

is

 

used

 

for

 

communication

 

between

 

the

 

management

 

module

 

and

 

a

 

service

 

processor

 

on

 

each

 

blade

 

server.
