Sharing a Redbook :[Practical Migration from x86 to Linux on IBM System z](http://www.redbooks.ibm.com/abstracts/sg248217.html?Open) (An IBM Redbooks publication)

here are many reasons why you would want to optimize your servers through virtualization using Linux on IBM® System 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 System z. It begins by examining the benefits of migrating  
workloads to Linux on System z. Here, we describe the workload centric  
method of information technology and then discuss the benefits of  
migrating workloads to Linux on System 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.
