Chapter 3. Virtualization

As you look for ways to maximize the return on your IT infrastructure investments,

consolidating workloads becomes an attractive proposition.

IBM Power Systems combined with PowerVM technology are designed to help you

consolidate and simplify your IT environment with the following key capabilities:

򐂰 Improve server utilization and sharing I/O resources to reduce total cost of ownership and

make better use of IT assets.

򐂰 Improve business responsiveness and operational speed by dynamically re-allocating

resources to applications as needed, to better match changing business needs or handle

unexpected changes in demand.

򐂰 Simplify IT infrastructure management by making workloads independent of hardware

resources, thereby enabling you to make business-driven policies to deliver resources

based on time, cost, and service-level requirements.
