Farms
You
can

configure

load

balancing

usi

ng

server

farms,

which

are

groups

of

networked

real

servers
(physical
servers

and

VMs)

that

contain

the

same

content

and

that

typically

reside

in

the

same

physical
location
in

a

data

center.
Websites
often

include

groups

of


servers

configured

in

a

se

rver

farm.

Load-balancing

software
distributes
client

requests

for

content

or

services

among

the

real

servers

based

on

the

configured

policy
and
traffic

classification,

server

availability

and

load,

and

other

factors.

If

one

server

goes

down,

another
server
can

take

its

place

and

continue

to

provide

the

same

content

to

the

clients

who

requested

it.
Guidelines
and

Restrictions

•
With
Dynamic

Workload

Scaling
configured
on

the

ACE,

the

real

servers
that

are

VMs

can

also
reside
in

a

re

mote

datacenter

(see

the

“Configuring

Dynamic

Workload

Scaling”

section

on
page
8-26 ).

A
server

farm

can

support

a

mix
of
IPv6

and

IPv4

real
servers,
and

can

be

associated

with
both
IPv6
and
IPv4

probes.

IPv6

requires

ACE
