IBM PowerVM Virtualization

  1. 1. Building the Foundation for a Dynamic Infrastructure ™ IBM PowerVM Virtualization Complexity can work its way into your IT infrastructure, driven by the introduc- tion of new applications and unantici- pated growth. However, adding a server each time you have new demand for a new application means that you also require additional floor or rack space, power, cooling, network inter- faces, data storage and administrative resources. Such complexity leads to inefficiency. The answer is consolidation and virtual- ization.
