Systems-management

 

capabilities

 

The

 

server

 

supports

 

an

 

optional

 

IBM

 

Remote

 

Supervisor

 

Adapter

 

II

 

SlimLine.

 

When

 

you

 

use

 

this

 

adapter,

 

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.

 

v

   

TCP/IP

 

offload

 

engine

 

(TOE)

 

support

 

The

 

Ethernet

 

controllers

 

in

 

the

 

server

 

support

 

TOE,

 

which

 

is

 

a

 

technology

 

that

 

offloads

 

the

 

TCP/IP

 

flow

 

from

 

the

 

microprocessors

 

and

 

I/O

 

subsystem

 

to

 

increase

 

the

 

speed

 

of

 

the

 

TCP/IP

 

flow.

 

When

 

an

 

operating

 

system

 

that

 

supports

 

TOE

 

is

 

running

 

on

 

the

 

server

 

and

 

TOE

 

is

 

enabled,

 

the

 

server

 

supports

 

TOE

 

operation.

 

See

 

the

 

operating-system

 

documentation

 

for

 

information

 

about

 

enabling

 

TOE.

 

Note:

 

As

 

of

 

the

 

date

 

of

 

this

 

document,

 

the

 

Linux

 

operating

 

system

 

does

 

not

 

support

 

TOE.

Reliability,

 

availability,

 

and

 

serviceability

 

features

 

Three

 

important

 

computer

 

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.

 

The

 

server

 

has

 

the

 

following

 

RAS

 

features:

 

v

   

Automatic

 

error

 

retry

 

and

 

recovery
