IBM DS4500 User Manual

 

 

 

 

 

 

After

 

the

 

storage

 

subsystem

 

is

 

installed

 

in

 

its

 

permanent

 

location,

 

you

 

must

 

cable

 

it

 

to

 

hosts,

 

drives,

 

and

 

other

 

external

 

devices,

 

depending

 

on

 

your

 

hardware

 

configuration.

 

This

 

chapter

 

addresses

 

the

 

following

 

cabling

 

and

 

configuration

When

 

fully

 

configured,

 

the

 

back

 

of

 

the

 

DS4500

 

Storage

 

Subsystem

 

can

 

accommodate

 

up

 

to

 

four

 

host-side

 

and

 

four

 

drive-side

 

mini

 

hubs.

 

Each

 

mini

 

hub

 

is

 

a

 

single,

 

removable

 

unit

 

that

 

provides

 

the

 

Fibre

 

Channel

 

interface

 

between

 

a

 

DS4500

 

Storage

 

Subsystem,

 

host

 

computers,

 

and

 

drives.

 

Each

 

mini

 

hub

 

has

 

two

 

small

 

form-factor

 

pluggable

 

(SFP)

 

module

 

ports.

 

An

 

SFP

 

module

 

is

 

inserted

 

into

 

a

 

mini-hub

 

port;

 

then,

 

a

 

fiber-optic

 

cable

 

is

 

inserted

 

into

 

the

 

SFP

 

module.

The

 

DS4500

 

Storage

 

Subsystem

 

uses

 

fiber-optic

 

cables

 

to

 

connect

 

to

 

other

 

Fibre

 

Channel

 

devices.

 

The

 

fiber-optic

 

cables

 

that

 

you

 

need

 

depend

 

on

 

the

 

type

 

of

 

optical

 

connectors

 

in

 

the

 

device

 

to

 

which

 

you

 

are

 

connecting

 

the

 

DS4500

 

Storage

 

Subsystem.

 

If

 

the

 

device

 

uses

 

SFP

 

modules

 

or

 

optical

 

interface

 

connectors,

 

then
