Chapter 1. Introduction to z/VM and Linux “Everything should be made as simple as possible, but not simpler.” — Albert Einstein 1 Virtualization is hot in the IT industry. The IBM mainframe, z/VM and its predecessors have been doing virtualization for four different decades. Today, it is the most functionally rich virtualization platform available. When Linux came to the IBM mainframe in 2000, it was a natural fit to run under z/VM. You can run many tens of Linux images on the same System z logical partition (LPAR). Some customers are running hundreds in production mode. With a z/VM and Linux infrastructure, you can reduce the time between deciding on the acquisition of new servers and then implementing them because new servers can be deployed in a matter of minutes. This powerful build and clone capability can enable you to launch new products and services without the exhaustive planning, purchasing, installing and configuring new hardware and software that can be associated with conventional discrete hardware servers. Development groups who need test environments built and rebuilt rapidly to enable them to efficiently deliver their projects, handling change management in the process can also benefit from this unique advantage. Some of the mainframe’s and z/VM’s best strengths are: ► Their virtualization capabilities are more mature and robust than any other hardware and hypervisor combination. ► z/VM provides a rich, functional and sophisticated level of systems management which can greatly benefit running large numbers of Linux servers. ► z/VM’s virtual switch (VSWITCH) makes networking Linux much simpler. ► Full volume backup of systems allows for complete disaster recovery when another data center is available. ► z/VM is one of the easiest operating systems to customize at the base installation level. There is only a relatively small number of configuration files. Properly set up, z/VM can run for months with little maintenance or administration required. Much function has been added to z/VM since version 5.2. Following is a brief summary of the function added in the last three releases. © Copyright IBM Corp. 2010. All rights reserved. 1
