7. Why Virtualize?
Server or data center consolidation
Average physical servers utilized only <15%
More efficient use of physical assets
Promotes greater centralization and security
Reduced capital and operating costs
“Green Computing” – less power / cooling
Flexibility - Allow IT agility
Dynamically respond to business needs
Virtual workloads are mobile and easy to create and manage
Business Continuity
Improve application availability
Key part of disaster recovery strategy

19. nominees are running on XenServer
Tesco, the world's third largest retailer, has embraced virtualization to enable the company to drive
growth and expansion in new geographies while increasing operational efficiency. By virtualizing
its servers to boost performance, Tesco nearly quadrupled the speed of store transactions while
cutting power consumption, overhead and carbon emissions and simplifying IT management.
Virtualizing 1,500 physical servers on XenServer, including 80 XenApp servers
Aiming for a conservative 10:1 consolidation
Hitting 70% CPU utilization (up from 6%)
Reducing carbon emissions by 20% (leveraging corporate "greening" budget)
