Virtualization is no longer an “emerging” technology. Its potential to increase the efficiency of IT infrastructures has become widely recognized. But key questions are raised in the early stages of virtualization planning: should it be implemented only for new projects, or applied to existing infrastructures? Should opportunities be pursued on a case-by-case basis, or targeted as a broader goal of IT strategy? What level of investment should be made, for what return? Before these questions can be answered, a broader understanding of the costs and benefits of virtualization at the enterprise level is needed.This paper by International Technology Group examines these questions, potential economic benefits of large-scale virtualization for UNIX and Linux servers and the potential impact of IBM System p Server Virtualization on your infrastructure.
