Abstract
This IBM® Redbooks® publication provides an overview of IBM System z® virtualization and networking when using Linux on System z.
Contents
For a complex environment, server consolidation helps reduce power consumption and cooling needs and reduces data center rack space requirements and server costs. It helps data centers better manage resources and resiliency. In addition, IBM z/VM® has a powerful mechanism to clone servers that allows existing servers to be cloned in a few minutes. The process leads to increased administration, system controls, and network complexity for your environment. It is important to ensure that you have an optimal network configuration. z/VM uses virtualization so administrators can manage resources on the IBM System z® platform.
Developed with hypervisor technology, z/VM provides flexibility, availability, and security capabilities for Linux instances, while it creates an isolated and protected environment for critical applications. The virtual network that is provided by z/VM for the Linux guests communication offers high throughputs and better reliability (failure tolerance).
Typically, z/VM provides three networking options:
