RD120

 

(Machine

 

Types

 

6444,

 

6445,

 

6446,

 

and

 

6447)

 

server

 

is

 

a

 

5-U-high,

 

high-performance

 

server.

 

It

 

is

 

ideally

 

suited

 

for

 

networking

 

environments

 

that

 

require

 

superior

 

microprocessor

 

performance,

 

improved

 

systems

 

management,

 

and

 

flexible

 

memory

 

and

 

data

 

management.

 

The

 

server

 

has

 

two

 

model

 

styles,

 

which

 

are

 

based

 

on

 

the

 

size

 

and

 

number

 

of

 

hard

 

disk

 

drive

 

bays:

 

v

   

The

 

3.5-inch

 

models

 

have

 

six

 

3.5-inch

 

hot-swap

 

hard

 

disk

 

drive

 

bays.

 

Install

 

only

 

3.5-inch

 

drives

 

in

 

these

 

models.

 

If

 

you

 

intend

 

to

 

install

 

an

 

optional

 

tape

 

drive,

 

the

 

tape

 

drive

 

will

 

occupy

 

two

 

of

 

the

 

six

 

3.5-inch

 

drive

 

bays.

 

  

  

v

   

The

 

2.5-inch

 

models

 

have

 

eight

 

2.5-inch

 

hot-swap

 

hard

 

disk

 

drive

 

bays

 

and

 

one

 

3.5-inch

 

tape-drive

 

bay.

 

Install

 

only

 

2.5-inch

 

hard

 

disk

 

drives

 

and

 

an

 

optional

 

3.5-inch

 

tape

 

drive

 

in

 

these

 

models.

 

  

 

Throughout

 

this

 

documentation,

 

the

 

terms

 

2.5-inch

 

models

 

and

 

3.5-inch

 

models

 

will

 

be

 

used

 

to

 

distinguish

 

between

 

the

 

server

 

styles.

 

Performance,

 

ease

 

of

 

use,

 

reliability,

 

and

 

expansion

 

capabilities

 

were

 

key

 

considerations

 

in

 

the

 

design

 

of

 

the

 

server.

 

These

 

design

 

features

 

make

 

it

 

possible

 

for

 

you

 

to

 

customize

 

the

 

system

 

hardware

 

to

 

meet

 

your

 

needs

 

today

 

and

 

provide

 

flexible

 

expansion

 

capabilities

 

for

 

the

 

future.
