WHY VIRTUALIZE?
What's Happening In The Data Center?
Admin: Machine Ratios
Power & Cooling

Green MovementManageability
Low CPU Utilization
Servers…Good! Server Sprawl…BAD!
Desktop/ApplicationVirtualization
Business Continuity
Server Consolidation
Test & Develop
Less than 10% servers and 1% desktops virtualized today
Progression of Virtualization
Types of Server Deployment
UnvirtualizedPhysical server with an operating system and no virtualization. System utilization at less than 10% to 20%.
Basic VirtualizationVirtualization with no live migration, limited automation and management; system utilization between 20% to 40%.
Advanced Virtualization Server + storage virtualization and use of management and automation tools. System utilization between 40% to 60% or more.

Other long term benefits include reduction of staffing costs and increasing business agility.
VIRTUALIZATION TECHNOLOGIES
Bare-metal Server Virtualization & Hyper-V
Bare-Metal Hypervisor
“Bare metal” hypervisor technologies are installed directly onto physical servers
The bare-metal approach is widely accepted as offering significantly better performance
Hyper-V is a bare metal hypervisor with each virtual machine (VM) running its own operating system, drivers, applications (such control panel).

DEPLOYMENT AND BENEFITS OF HYPER-V
Hardware RequirementsComponent RequirementProcessor •Minimum: An x64 processor with Hardware-assisted virtualization. This is
available in processors that include a virtualization option; specifically, Intel VT or AMD Virtualization.•Hardware Data Execution Protection (DEP) must be available and be enabled.
Specifically, you must enable Intel XD bit (execute disable bit) or AMD NX bit (no execute bit).•Recommended: 2 GHz or faster
Memory •Minimum: 1 GB RAM; Recommended: 2+ GB RAM•Maximum (64-bit systems): 32 GB
Available Disk Space
•Minimum: 10 GB; Recommended: 40 GB or greater•Note: Computers with more than 16 GB of RAM will require more disk space for paging, hibernation, and dump files

Microsoft Assessment and Planning Toolkit
Microsoft Assessment and Planning Toolkit provides the ability to conduct network-wide assessment and determine the readiness for migration to Windows Server 2008 and Hyper-V
As a plus, this toolkit will determine the power a cooling cost savings as well
Available at www.microsoft.com/MAP or partner.microsoft.com/SAAssessment
Designed for Security
Hyper-V runs as a thin layer of software that sits between the hardware and the virtual machines.
The host operating system (Windows Server 2008) can be installed as server core.
This enables greater performance, a smaller footprint, and a smaller attack surface for increased security.
Benefits of Hyper-v Virtualization
Reduced total cost of ownershipMaximize hardware utilization
Reduce power consumption
Rapid deploymentsReal-time provisioning
From “Buy it” to Login in less than 60 seconds
Numerous configurations and options to sellHigh availability options
Managed hosting offers
Very favorable Microsoft licensing termsWindows Server 2008 Datacenter => Right for unlimited number of guests
System Center makes management of virtual farms easy
