v

   

Memory

 

mirroring

 

Some

 

models

 

support

 

memory

 

mirroring.

 

Memory

 

mirroring

 

replicates

 

and

 

stores

 

data

 

in

 

DIMMs

 

within

 

two

 

branches

 

simultaneously.

 

To

 

support

 

memory

 

mirroring,

 

you

 

must

 

have

 

at

 

least

 

two

 

pairs

 

of

 

DIMMs

 

installed

 

(a

 

pair

 

in

 

each

 

branch).

 

Pairs

 

of

 

DIMMs

 

that

 

are

 

next

 

to

 

each

 

other

 

(for

 

example,

 

DIMM

 

slot

 

1

 

and

 

DIMM

 

slot

 

4)

 

within

 

the

 

channels

 

of

 

the

 

same

 

branch

 

must

 

be

 

identical

 

pairs

 

of

 

full-buffered,

 

dual

 

inline

 

memory

 

modules

 

(DIMMs).

v

   

Online-spare

 

memory

 

Some

 

models

 

support

 

online-sparing

 

memory.

 

Online-spare

 

memory

 

disables

 

a

 

failed

 

rank

 

pair

 

of

 

DIMMs

 

from

 

the

 

system

 

configuration

 

and

 

activates

 

an

 

online-spare

 

rank

 

pair

 

of

 

DIMMs

 

to

 

replace

 

the

 

failed

 

rank

 

pair

 

of

 

DIMMs.

 

For

 

an

 

online-spare

 

pair

 

of

 

DIMMs

 

to

 

be

 

activated,

 

you

 

must

 

enable

 

this

 

feature

 

and

 

have

 

installed

 

an

 

additional

 

pair

 

of

 

DIMMs

 

of

 

the

 

same

 

speed,

 

type,

 

size

 

(or

 

larger),

 

and

 

technology

 

as

 

the

 

failed

 

pair

 

of

 

DIMMs.

Redundant

 

power

 

capabilities

 

Some

 

models

 

support

 

up

 

to

 

two

 

835-watt

 

power

 

supplies,

 

which

 

provide

 

redundancy

 

and

 

hot-swap

 

capability

 

for

 

a

 

typical

 

configuration.

 

If

 

the

 

maximum

 

load

 

on

 

the

 

server

 

is

 

less

 

than

 

835

 

watts

 

and

 

a

 

problem

 

occurs

 

with

 

one

 

of

 

the

 

power

 

supplies,

 

the

 

other

 

power

 

supply

 

can

 

meet

 

the

 

power

 

requirements.

 

v

   

ServeRAID

 

support

 

Some

 

models

 

support

 

ServeRAID

 

adapters

 

to

 

create

 

redundant

 

array

 

of

 

independent

 

disks

 

(RAID)

 

configurations.

 

Some

 

models

 

also

 

have

 

integrated

 

RAID

 

level-0

 

and

 

level-1

 

support.

 

v

   

Symmetric

 

multiprocessing

 

(SMP)

 

The

 

server

 

supports

 

up

 

to

 

two

 

Intel

 

Xeon

 

microprocessors.

 

Each

 

microprocessor

 

provides

 

symmetric

 

multiprocessing

 

capability.

 

When

 

you

 

install

 

the

 

second

 

microprocessor,

 

this

 

will

 

enhance

 

the

 

performance

 

of

 

the

 

server.

 

v

   

Systems-management

 

capabilities

 

The

 

server

 

supports

 

an

 

optional

 

Remote

 

Supervisor

 

Adapter

 

II

 

SlimLine,

 

which

 

provides

 

service-processor

 

functions

 

in

 

addition

 

to

 

those

 

that

 

the

 

BMC

 

provides.

 

When

 

this

 

adapter

 

is

 

used

 

with

 

the

 

systems-management

 

software

 

that

 

comes

 

with

 

the

 

server,

 

you

 

can

 

manage

 

the

 

functions

 

of

 

the

 

server

 

locally

 

and

 

remotely.

 

The

 

Remote

 

Supervisor

 

Adapter

 

II

 

SlimLine

 

also

 

provides

 

system

 

monitoring,

 

event

 

recording,

 

and

 

dial-out

 

alert

 

capability.

 

See

 

the

 

documentation

 

that

 

comes

 

with

 

your

 

systems-management

 

software

 

for

 

more

 

information.

Reliability,

 

availability,

 

and

 

serviceability

 

Three

 

important

 

server

 

design

 

features

 

are

 

reliability,

 

availability,

 

and

 

serviceability

 

(RAS).

 

The

 

RAS

 

features

 

help

 

to

 

ensure

 

the

 

integrity

 

of

 

the

 

data

 

that

 

is

 

stored

 

in

 

the

 

server,

 

the

 

availability

 

of

 

the

 

server

 

when

 

you

 

need

 

it,

 

and

 

the

 

ease

 

with

 

which

 

you

 

can

 

diagnose

 

and

 

repair

 

problems.
