Configuring
Real
Servers
and
Server
Farms
Date:
3/
28/12
This
chapter
describes
how
to
configure
real
servers
and
server
farms
on
the
Cisco
Application
Control
Engine
(ACE)
using
Cisco
Application
Networking
Manager
(ANM).
Note
When
naming
ACE
objects
(such
as
a
real
server,
virtual
server,
parameter
map,
class
map,
health
probe,
and
so
on),
enter
an
alphanumeric
string
of
1
to
64
characters,
which
can
include
the
following
special
characters:
underscore
(_),
hyphen
(-),
dot
(.),
and
asterisk
(*)
.
Spaces
ar
e
not
al
lowed.
If
you
are
using
ANM
with
an
ACE
module
or
ACE
appliance
and
you
configure
a
named
object
at
the
ACE
CLI,
keep
in
mind
that
ANM
does
not
support
all
of
the
special
characters
that
the
ACE
CLI
allows
you
to
use
when
configuring
a
named
object.
If
you
use
special
characters
that
ANM
does
not
support,
you
may
not
be
able
to
import
or
manage
the
ACE
using
ANM.

Information
About
Server
Load
Balancing
Server
load
balancing
(SLB)
is
the
process
of
deciding
to
which
server
a
load-balancing
device
should
send
a
client
request
for
service.
For
example,
a
client
request
can
consist
of
an
HTTP
GET
for
a
Web
page
or
an
FTP
GET
to
download
a
file.
The
job
of
the
load
balancer
is
to
select
the
server
that
can
successfully
fulfill
the
client
request
and
do
so
in
the
shortest
amount
of
time
without
overloading
either
the
server
or
the
server
farm
as
a
whole.
