Memory

 

mirroring

 

improves

 

the

 

reliability

 

of

 

memory

 

by

 

writing

 

information

 

to

 

the

 

main

 

memory

 

and

 

redundant

 

locations

 

in

 

a

 

mirrored

 

pair

 

of

 

DIMMs.

Online-spare

 

memory

 

disables

 

a

 

failed

 

pair

 

of

 

DIMMs

 

from

 

the

 

system

 

configuration

 

and

 

activates

 

an

 

online-spare

 

DIMM

 

pair

 

to

 

replace

 

the

 

failed

 

pair.

 

v

   

PCI

 

Express

 

adapter

 

capabilities

 

The

 

server

 

has

 

two

 

slots

 

for

 

low-profile

 

PCI

 

Express

 

x4

 

adapters.

 

These

 

slots

 

accept

 

x8

 

adapters,

 

but

 

the

 

adapters

 

will

 

operate

 

as

 

x4

 

adapters.

 

The

 

server

 

also

 

has

 

two

 

slots

 

for

 

PCI

 

Express

 

x8

 

adapters

 

(on

 

the

 

riser

 

card,

 

full-height,

 

one

 

full-length

 

and

 

one

 

half-length).

 

Note:

 

You

 

can

 

replace

 

these

 

PCI

 

Express

 

x8

 

slots

 

with

 

PCI-X

 

133

 

MHz

 

slots

 

by

 

replacing

 

the

 

PCI

 

Express

 

riser-card

 

assembly

 

with

 

an

 

optional

 

PCI-X

 

riser-card

 

assembly.

 

v

   

Redundant

 

connection

 

The

 

addition

 

of

 

an

 

optional

 

network

 

interface

 

card

 

(NIC)

 

provides

 

a

 

failover

 

capability

 

to

 

a

 

redundant

 

Ethernet

 

connection.

 

If

 

a

 

problem

 

occurs

 

with

 

the

 

primary

 

Ethernet

 

connection,

 

all

 

Ethernet

 

traffic

 

that

 

is

 

associated

 

with

 

the

 

primary

 

connection

 

is

 

automatically

 

switched

 

to

 

the

 

redundant

 

NIC.

 

If

 

the

 

applicable

 

device

 

drivers

 

are

 

installed,

 

this

 

switching

 

occurs

 

without

 

data

 

loss

 

and

 

without

 

user

 

intervention.

 

v

   

Redundant

 

cooling

 

and

 

power

 

capabilities

 

The

 

server

 

supports

 

up

 

to

 

10

 

hot-swap

 

fans,

 

in

 

multiples

 

of

 

5,

 

which

 

provide

 

redundant

 

cooling.

 

Redundant

 

cooling

 

enables

 

continued

 

operation

 

if

 

one

 

of

 

the

 

fans

 

fails.

 

The

 

server

 

supports

 

up

 

to

 

two

 

835-watt

 

ac

 

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.

 

Note:

 

A

 

700-watt-48

 

volt

 

dc

 

power

 

supply

 

option

 

may

 

be

 

available.

 

The

 

dc

 

power

 

supplies

 

provide

 

redundancy

 

but

 

no

 

hot-swap

 

capability.

 

v

   

RAID

 

support

 

The

 

server

 

supports

 

an

 

internal

 

ServeRAID-8k

 

or

 

8k-l

 

SAS

 

Controller,

 

which

 

is

 

required

 

for

 

you

 

to

 

use

 

the

 

hot-swap

 

hard

 

disk

 

drives

 

and

 

to

 

create

 

redundant

 

array

 

of

 

independent

 

disks

 

(RAID)

 

configurations.
