Virtualization technologies allow IT organizations to consolidate workloads running on multiple operating systems and software stacks and allocate platform resources dynamically to meet specific business and application requirements. Leadership virtualization has become the key technology to efficiently deploy servers in enterprise data centers to drive down costs and become the foundation for server pools and cloud computing technology. Therefore, the performance of this foundation technology is critical for the success of server pools and cloud computing.
Virtualization may be employed to:
- Consolidate multiple environments, including underutilized servers and systems with varied and dynamic resource requirements
- Grow and shrink resources dynamically, derive energy efficiency, save space, and optimize resource utilization
- Deploy new workloads through provisioning virtual machines or new systems rapidly to meet changing business demands
- Develop and test applications in secure, independent domains while production can be isolated to its own domain on the same system
- Transfer live workloads to support server migrations, balancing system load, or to avoid planned downtime
- Control server sprawl and thereby reduce system management costs
The latest advances in IBM® PowerVM™ offer broader platform support, greater scalability, higher efficiency in resource utilization, and more flexibility and robust heterogeneous server management than ever before. This paper will discuss the advantages of virtualization, highlight IBM PowerVM, and analyze the performance of virtualization technologies using industry-standard benchmarks.
