    There are many reasons why you would want to optimize your servers through virtualization using Linux on IBM Z®:

    • Too many distributed physical servers with low utilization
    • A lengthy provisioning process that delays the implementation of new applications
    • Limitations in data center power and floor space
    • High total cost of ownership (TCO)
    • Difficulty allocating processing power for a dynamic environment

    This IBM Redbooks® publication provides a technical planning guide and example for IT organizations to migrate from their x86 environment to Linux on IBM Z. It begins by examining the benefits of migrating workloads to Linux on IBM Z. Here, we describe the workload centric method of information technology and then discuss the benefits of migrating workloads to Linux on IBM Z.

    Next, we describe total cost of ownership analyses and we guide you in understanding how to analyze your environment before beginning a migration project. We also assist you in determining the expected consolidation ratio for a given workload type.

    We also describe virtualization concepts along with describing the benefits of migrating from the x86 environment to guests residing on an IBM z/VM® single system image with live guest relocation.

    This IBM Redbooks publication walks you through a migration approach, includes planning worksheets, as well as a chapter to assist you in analyzing your own systems. We also discuss post migration considerations such as acceptance testing of functionality and performance measurements.
