Historically, enterprise infrastructures have used single function servers assigned to a specific application or service to manage growth. As infrastructures have grown, the strategy to expand was to add another server - often multiplied other needs for supporting hardware that complicated the issue exponentially. This situation is known as "server sprawl" and is it more costly than most businesses realize.
Dedicated servers can often experience either a low level of CPU-utilization; often under 10 percent. Moreover, dedicated servers can impose a risk of under-servicing the business because of the static design of the infrastructure-it is very difficult to reassign resources quickly. Industry average management ratios of administrators to devices is 1 to 30, world-class blade environments can achieve ratios of over 1:100. Environments plagued by server sprawl are much less efficient.

Through a program of server consolidation and adopting virtualization technology on the HP BladeSystem infrastructure, the Customer can:
- Contain server sprawl and consolidate on scalable platforms
- Better manage the environment with fewer resources
- Save money through better utilization of current and future resources
- Increase reliability with flexibility
- Improve business agility and IT responsiveness
By implementing an IT consolidation strategy that uses virtualization, today's enterprise infrastructure can maximize both hardware and software capabilities while reducing management and maintenance tasks. The c-class BladeSystem infrastructure adds the capability to virtualize storage, network, power, and cooling along with the leading server virtualization suppliers to collapse the complexity of computing environment. Joined with the new automation capabilities HP offers solutions that significantly decrease hardware inventory, streamline system infrastructure, and simplify IT management.

This guide outlines the concepts involved in virtualization, methods for implementation, and considerations for operation. Focused on multiple partners including VMware, Citrix, PolyServe and F5 Networks, virtualization is treated in the broadest possible sense as a way to change the relationships between hardware and software to make IT more responsive to business need driven change.
