Virtualization
Chapter 3.
IBM Advance POWER Virtualization (PowerVM) is a feature use to consolidate workload to
deliver cost savings and improve infrastructure responsiveness. As we look for ways to
maximize the return on your IT infrastructure investments, consolidating workloads and
increasing server use becomes an attractive proposition.
IBM Power Systems, combined with PowerVM technology, are designed to help you
consolidate and simplify your IT environment. The following list details key capabilities:
Improve server use by consolidating diverse sets of applications.
Share CPU, memory, and I/O resources to reduce total cost of ownership.
Improve business responsiveness and operational speed by dynamically re-allocating
resources to applications as needed, to better anticipate changing business needs.
Simplify IT infrastructure management by making workloads independent of hardware
resources, enabling you to make business-driven policies to deliver resources based on
time, cost, and service-level requirements.
Move running workloads between servers to maximize availability and avoid planned
downtime
