{

HW independence of O/S and apps

{

VM can be provisioned to any system

{

Manage O/S and apps as one unit

Flexible, Affordable Infrastructure

After Virtualization

{

Software tied to hardware

{

Single OS image per machine

{

One application workload per OS

Inflexible, Costly Infrastructure

Before Virtualization

(7)

Type 1 (Native or Bare-Metal)

{

Hypervisors run directly on the

host's hardware as a hardware

control and guest o/s monitor

{

Guest operating system runs on

another level above the hypervisor

Type 1 vs. Type 2 Virtualization

Type 2 (Hosted)

{

Hypervisors run within a

conventional operating system

environment

{

Guest operating systems run at the

third level above the hardware

1. Encapsulation

{

Servers are developed and saved into

a few files (Virtual Machine)

Virtual Bios = Nvram

Text file defining its configuration = w2k.vmx

Disk file that contains its data = w2k.vmdk

{

An entire Server can be managed as a

simple collection of data files

{

Entire state of the VM is encapsulated

including:

Memory

Disk images

I/O device state

(10)

2. Hardware Independence

{

Portability Across Different x86

Hardware

Utilize Different hardware platforms

Server can be transferred through

Time and Space

Time: Store Server in a file

Space: Transfer Server over a

network

Rapid Server Provisioning

Run a virtual machine on any server

without modification

Hardware Independence

(11)

3. Isolation

{

Each virtual machine is isolated from

others

{

Totally separate OS, registry,

applications and data files

{

Immune to guest OS crashes, viruses

or corruption

{

Fault, performance, and security

isolation

{

CPU, RAM, Disk, and Network

resource controls*

{

Guaranteed service levels*

% Utilization

Partitioning

Run multiple VMs

simultaneously on a single server

4. Partitioning

{

Dynamically map computing resources

VM based on business requirements

{

Lower IT costs through increased

efficiency, flexibility and responsiveness

{

Provision new services and change the

amount of resources dedicated to a

software service

{

Treat your Data Center as a single pool

of processing, storage and networking

Considering Virtualization?

Keep the Following in Mind:

Strategy (replace, expand)

Which systems to virtualize

Operating systems involved

Hardware platforms

Administrative issues

Hardware reuse, replacement

Licensing issues

Legacy software considerations

Additional infrastructure requirements

Prototype testing

Migration

Stream Virtual Disks No No Yes

(Provisioning Server and XenApp) Provisioning Server allows you to create virtual disks (vDisks) that represent a computer hard drive, and then relocate that vDisk on an OS Provisioning Server, or on a storage device that has access to a

provisioning Server. Once the vDisk is available, the target device no longer needs its local hard drive to operate; it boots directly across the network. Provisioning Server streams the contents of the vDisk to the target device on demand, in real time, and the target device behaves as if it is running from its local drive.
