There are many reasons why you would want to optimize your servers through
virtualization using Linux® on System z®:
- Too many distributed physical servers with low utilization
- A lengthy provisioning process that delays the implementation of new
- 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 reference for IT
organizations that are considering a migration to Linux on System z.
The overall focus of the content in this book is to walk the reader through some of
the important considerations and planning issues that you could encounter
during a migration project. Within the context of a pre-existing Unix based or x86
environment, we attempt to present an end-to-end view of the technical
challenges and methods necessary to complete a successful migration to Linux
on System z.
