Virtual Server 2005 provides virtualization capabilities that allow consolidating servers to reduce costs. It offers key benefits like increased hardware utilization, single point of management, and test environments. Customers are seeing savings of millions of dollars by deploying hundreds to thousands of virtual machines. The architecture isolates guest operating systems and applications from physical hardware through virtual devices and resource management. This enables easy migration of workloads between physical and virtual servers with minimal downtime.

2. What is Virtualization All
About? Key Benefits
Server Memory  Under-utilized processors now
in shared environment
 Single point of management
 Cut down on sprawl
 Reduce costs for aging
hardware
 Manage one big piece of
hardware instead of many
smaller
 Provides a clean test
environment

3. • 20 early adoption customers with 600 virtual machines in production
(2000 virtual machines being rolled out)
• Over 12,000 downloads of Virtual Server 2005 evaluation software
“We think we will be saving up to $7.5 million over the next 5 years with
Virtual Server 2005” --
-Michael Mark, Senior Planner, Allstate
"Virtual Server is going to blast this market wide open... I'd expect some large
number of deployments by the end of next year -- 100,000 is not out of the question.“
-Tom Bittman, Gartner

4. Common Scenarios
Test/development automation
Sandbox environments for increased quality
• Test your AD migration steps with a virtual DC
• Validate patches against standard images
• Evaluate solutions that require multiple servers
• Help desk access to variety of supported OS’s
• Provide common development platforms
Departmental/branch consolidation
Multiple applications/services on fewer servers for remote
manageability
• Rapid provisioning on the fly
• Reduce hardware costs
• Low provisioning times
NT4 Server Consolidation
Consolidate NT4 physical servers onto fewer, current servers
• Reduce hardware support costs, data center infrastructure demands
• Solid, supported migration tools

 Same file format, same hardware emulation
 Build anywhere, move anywhere (SCSI only on Virtual Server, Sound
card only on Virtual PC)
 No “hardware detection” step

11. Migration – Reinstall then move
data? 1. Install the core OS and
service packs (a few
Server hours)
Memory
2. Install the application(s)
(another few hours)
3. Virtual Server
Migrate the data (tape or
xcopy?) Toolkit
4. Turn off the old box
5. Turn on the new box
VMWare
6. Do all this with minimal .dsk files

8. Repeat for each server installations as just
another physical
machine being migrated
to Virtual Server
