VMware Discovery

VMware

 

products

 

such

 

as

 

ESX

 

Server

 

are

 

used

 

to

 

create

 

the

 

virtual

 

machines

 

in

 

the

 

form

 

of

 

a

 

set

 

of

 

configuration

 

and

 

disk

 

files

 

that

 

together

 

perform

 

all

 

the

 

functions

 

of

 

a

 

physical

 

machine.

 

Through

 

the

 

virtualization

 

platform,

 

you

 

run

 

the

 

virtual

 

machines,

 

install

 

operating

 

systems,

 

run

 

applications,

 

and

 

configure

 

the

 

virtual

 

machines.

 

This

 

includes

 

identifying

 

the

 

virtual

 

machine

 

resources,

 

such

 

as

 

a

 

storage

 

device.

 

VMware Terminology Overview

Virtual

 

Center

 

monitors

 

and

 

manages

 

components

 

of

 

your

 

virtual

 

and

 

physical

 

infrastructure.

 

These

 

components

 

are

 

as

 

follows:

 

Virtual

 

machines:

 

A

 

virtualized

 

x86

 

personal

 

computer

 

environment

 

in

 

which

 

a

 

guest

 

operating

 

system

 

and

 

associated

 

application

 

software

 

can

 

run.

 

Multiple

 

virtual

 

machines

 

can

 

operate

 

on

 

the

 

same

 

managed

 

host

 

machine

 

concurrently.

 

Hosts:

 

The

 

physical

 

computers

 

on

 

which

 

the

 

virtualization

 

platform

 

software,

 

such

 

as

 

ESX

 

Server,

 

is

 

installed.

 

They

 

are

 

hosts

 

to

 

the

 

virtual

 

machines.

 

Resources:

 

Selected

 

resources

 

belonging

 

to

 

the

 

host

 

and

 

assigned

 

to

 

the

 

virtual

 

machines

 

that

 

are

 

resident

 

on

 

that

 

host.

 

The

 

managed

 

resources

 

are

 

CPU,

 

memory,

 

disk

 

space,

 

and

 

I/O.

 

Virtual

 

Center

 

uses

 

the

 

resources

 

to

 

provide,

 

through

 

the

 

VMware

 

DRS

 

components,

 

various

 

options

 

for

 

monitoring

 

the

 

status

 

of

 

the

 

resources

 

and

 

adjusting

 

or

 

suggesting

 

adjustments

 

to

 

the

 

virtual

 

machines.

 

Virtual

 

Infrastructure

 

Client

 

(VIC):

 

The

 

UI

 

used

 

to

 

connect

 

to

 

the

 

Virtual

 

Center

 

Server.

 

VMware Discovery in ADM

ADM

 

can

 

discover

 

VMware

 

environment,

 

track

 

changes

 

in

 

the

 

environment,

 

and

 

find

 

dependencies

 

within

 

that

 

environment.

A

 

Virtual

 

Center

 

host

 

is

 

the

 

physical

 

machine

 

on

 

which

 

the

 

virtual

 

machines

 

are

 

running.

 

All

 

virtual

 

machines

 

within

 

the

 

VMware

 

Infrastructure

 

environment

 

are

 

physically

 

on

 

ESX

The

 

term

 

“host”

 

in

 

this

 

Help

 

system

 

refers

 

to

 

the

 

ESX

that
