Sharing a Redbook : Practical Migration from x86 to Linux on IBM System z (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.
