During

of

Overview
Configuring
ANM

high

availabitly

depends

on

whether

you

are

using

ANM

Virtual

Appliance

or

ANM
server.
ANM
Vitual

Appliance
You
can

implement

redundancy

for

ANM

Virtual

Appliance

using

the

high

availability

feature

of

the
underlying
VMware

vSphere

platform.

VMware

HA

(High

Availability)

detects

faults

in

the

operation
of
managed

vi

rtual

machines

and

provides

redundancy

in

case

of

a

fai

lure.
You
implement

VMware

HA

for

ANM

Virtual

Appliance

in

the

same

manner

as

for

any

VM-based
application
running

on

VMware

i

nfrastructure;

that

is,

ANM

Virtual

Appliance

does

not


impose

any
special
requirements

for

implementing

VMware

HA.
For
additional

information

about

installing

ANM

Virtual

Appliance,
