What is Virtualization?What is Virtualization?
• Virtualization allows one computer to do the job of multiple computers.
• Virtual environments let one computer host multiple operating systems at the same time

Computer virtualization is the process of running two or more logical computer system on one set of physical hardware.

Background and EvolutionBackground and Evolution
• Virtualization arose from a need in the 1960’s to partition large mainframe hardware.
• Improved in the 1990s to allow mainframes to multitask.
• First implemented by IBM more than 30 years ago.

How does it work?How does it work?
• Virtualization transforms hardware into software.
• It is the creation of a fully functional virtual computer that can run its own applications and operating system.
• Creates virtual elements of the CPU, RAM, and hard disk.

Server VirtualizationServer Virtualization
• Virtualization one of the most effective tools for cost effective, greener computing.
• Reduce the cost of power and cooling through the consolidation and virtualization of the IT server infrastructure.
• $300 -$600 per year in energy savings for every server removed through virtualization based consolidation.
• Virtualization helps a company/enterprise lower power and cooling consumption, by reducing the machines and servers it needs.

Virtualization ProgressVirtualization Progress • Establish phased approach for quick wins
• Migrate initial servers from ‘early adopter’ teams
• Comprehensive project plan and management system in place – Integrated business priorities with transformational objectives – ‘Work in progress’ approach to maximize server migrations –Pipeline, process, technical, finance and communications support
• Developed internal business case and cash flow analysis using specific server costs, detailed labor analysis, migration expense

Client requirements• Improve IT equipment utilization• Reduce IT hardware requirements
Solution • Advanced POWER Virtualization (APV)
and VMWare
• Reduced number of physical servers – Wintel from 11,000 to 1,500 – UNIX from 8,500 to 1,500
• Three times improvement in server utilization
• Formed a Virtualization Center of
Excellence to implement best practices across geographies
Benefits• Operational savings of up to 70% –Space, power and cooling, maintenance, software support and personnel costs
