Introduction

This

chapter

describes

the

operating

specifications,

features,

and

components

for

the

IBM

TotalStorage

DS4100

storage

server

(hereafter

referred

to

as

DS4100

or

storage

server).

This

chapter

also

includes

a

list

of

hardware

that

comes

with

the

storage

server.

Overview

IBM

DS4000

solutions

support

the

large

and

growing

data

storage

requirements

of

business-critical

applications.

These

scalable

IBM

DS4000

solutions

offer

you

data

access

and

protection

to

meet

your

existing

enterprise

storage

requirements

and

prepare

for

the

future.

Designed

for

data

archival,

data

reference,

and

near-line

storage

applications,

the

DS4100

utilizes

the

latest

Serial

Advanced

Technology

Attachment

(SATA)

disk

drive

technology.

The

DS4100

supports

up

to

fourteen

1.5

Gbps

250

GB

SATA

disk

drive

modules,

offering

up

to

3.5

terabytes

(TB)

of

capacity

per

enclosure.

Note:

SATA

hard

drive

CRUs

cannot

be

interchanged

with

the

fibre-channel

hard

drive

CRUs

that

are

supported

in

other

DS4000

storage

products.

The

DS4100

can

be

used

in

storage

area

networks

to

satisfy

the

needs

of

various

fixed

content,

data-reference

applications

that

require

large

amounts

of

storage

capacity

but

do

not

have

the

high

utilization

and

access

characteristics

satisfied

by

fibre

channel

disk

drive

storage.

The

storage

server

provides

continuous,

reliable

service,

using

hot-swap

technology

for

easy

replacement

without

shutting

down

the

system.

IBM

currently

offers

two

versions

of

the

DS4100:

v

DS4100

base

storage

server

(Machine

Type

1724,

Model

100)

v

DS4100

single-controller

storage

server

(Machine

Type

1724,

Model

1Sx)

About

the

DS4100

base

storage

server

The

DS4100

base

(dual-controller)

storage

server

(Machine

Type

1724,

Model

100)

is

a

rack-mountable

storage

server

that

comes

with

two

RAID

controllers,

two

power

supplies,

and

two

cooling

units.

It

provides

dual,

redundant

controllers,

redundant

cooling,

redundant

power,

and

battery

backup

of

the

RAID

controller

cache.

The

DS4100

base

storage

server

is

designed

to

provide

maximum

host

and

drive-side

redundancy,

enabling

full

redundant

drive

loop

support

to

additional

disk

storage

capacity

in

the

drive

expansion

enclosures

via

the

drive

loop

port

from

each

RAID

controller.

In

addition,

each

RAID

controller

supports

direct

attachment

of

two

hosts

that

contain

two

fibre

channel

host

bus

adapters

each.

External

cables

and

small

form-factor

pluggable

(SFP)

modules

connect

the

storage

server

to

the

storage

expansion

unit

and

the

host

servers.

Up

to

seven

DS4000

EXP100

storage

expansion

units

can

be

connected

together

with

the

DS4100

base

storage

server

in

a

fibre-channel

loop,

providing

connections

to

a

maximum

of

112

hard

drives.

With

the

DS4100

base

storage

server,

you

can

configure

RAID-protected

storage

solutions

of

up

to

28

TB

(by

connecting

the

DS4100

base

storage

server

to

seven

drive

expansion

enclosures

with

250

GB

SATA

hard

drives),

providing

economical

and

scalable

storage

for

your

rapidly

growing

application

needs

for

limited

access,

data

reference

storage

capacity.

The

DS4100

base

storage

server

is

designed

with

redundant

2

Gbps

fibre

channel
