Book description
There 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.
