Users

 

and

 

systems

 

are

 

the

 

most

 

prevalent

 

object

 

types

 

in

 

a

 

large

 

database.

  

Typically,

 

on

 

creation,

 

these

 

types

 

of

 

objects

 

take

 

4000

 

bytes.

  

A

 

day’s

 

audit

 

adds

 

around

 

an

 

additional

 

700

 

bytes

 

of

 

data

 

per

 

object.

   

Although

 

these

 

figures

 

are

 

very

 

small,

 

because

 

of

 

wasted

 

space

 

on

 

the

 

Object

 

Directory

 

Server’s

 

hard

 

disk,

 

the

 

actual

 

disk

 

size

 

occupied

 

by

 

the

 

Object

 

Directory

 

can

 

be

 

4x

 

or

 

more

 

larger.

 

 

Virtual

 

Servers

 

McAfee

 

Endpoint

 

Encryption

 

Manager

 

can

 

be

 

run

 

from

 

a

 

Virtual

 

Server

 

for

 

lower

 

numbers

 

of

 

Endpoints.

 

McAfee

 

recommends

 

physically

 

dedicated

 

hardware

 

for

 

high

 

numbers

 

of

 

Endpoints.

 

 

Performance

 

of

 

virtual

 

systems

 

is

 

dependent

 

on

 

many

 

factors

 

that

 

can

 

significantly

 

affect

 

the

 

overall

 

product

 

performance

 

when

 

compared

 

to

 

physically

 

dedicated

 

hardware.

 

High

speed

 

access

 

to

 

the

 

data

 

within

 

the

 

Object

 

Directory

 

is

 

required

 

and

 

must

 

be

 

carefully

 

considered

 

and

 

evaluated

 

in

 

a

 

Virtual

 

Server

 

Environment.

 

 

Current

 

testing

 

of

 

Virtual

 

Servers

 

running

 

EEPC

 

operates

 

within

 

a

 

set

 

numbers

 

of

 

database

 

objects.

 

McAfee’s

 

experience

 

shows

 

that

 

performances

 

issue

 

arising

 

from

 

the

 

use

 

of

 

Virtual

 

Servers

 

is

 

a

 

result

 

of:

 

 

 

Lack

 

of

 

resources

 

dedicated

 

to

 

the

 

virtual

 

server.

 

 

Dynamically

 

assigned

 

resources

 

to

 

the

 

virtual

 

server

 

which

 

starves

 

it

 

of

 

the

 

necessary

 

performance

 

during

 

peak

 

periods.

 

 

Slow

 

or

 

reduced

 

disk

 

access,

 

resulting

 

in

 

a

 

slower

 

access

 

to

 

the

 

Object

 

Directory.

 

 

McAfee

 

supports

 

the

 

use

 

of

 

Virtual

 

Servers

 

running

 

the

 

administrative

 

functionality

 

of

 

EEPC

 

provided

 

the

 

appropriate

 

resources

 

are

 

fully

 

dedicated

 

to

 

the

 

Virtual

 

Server

 

at

 

all

 

times.

  

If

 

performance

 

problems

 

are

 

experienced,

 

the

 

resources

 

available

 

to

 

the

 

Virtual

 

Server

 

need

 

to

 

be

 

increased.

  

Please

 

refer

 

to

 

the

 

recommended

 

server

 

specifications

 

as

 

the

 

minimum

 

resources

 

fully

 

assigned

 

to

 

the

 

Virtual

 

Server

 

at

 

all

 

times.

  

These

 

resources

 

apply

 

to

 

the

 

specific

 

image,

 

and

 

not

 

to

 

the

 

overall

 

resources

 

of

 

the

 

host.

 

Customers

 

need

 

to

 

follow

 

the

 

recommendations

 

of

 

McAfee

 

Support

 

and

 

raise

 

a

 

support

 

ticket

 

for

 

the

 

issues

 

related

 

to

 

a

 

Virtual

 

Server.

  

These

 

recommendations

 

can

 

vary

 

from

 

tweaking

 

of

 

server

 

and

 

machine

 

settings

 

as

 

specified

 

in

 

this

 

guide

 

all

 

the

 

way

 

to

 

moving

 

the

 

EEPC

 

management

 

environment

 

to

 

physical

 

hardware

 

as

 

a

 

last

 

resort

 

if

 

necessary.

 

 

By

 

engaging

 

McAfee

 

professional

 

services,

 

they

 

will

 

assist

 

you

 

in

 

adequately

 

scoping

 

your

 

deployment

 

hardware

 

needs

 

and

 

can

 

recommend

 

a

 

best

 

practices

 

approach.

  

 

As

 

the

 

technology

 

is

 

evolving

 

and

 

better

 

VM

are

 

coming

 

online,

 

virtual
