Linux and System z virtualization
"We have to do more with less." Sound familiar? In the data processing sense, that typically means fewer servers, less floor space, less power consumed and reduced budget for software and staff. . .
System z mainframes running Linux provide the ability to address these pressure points. And, the IBM mainframe system provides users with the ability to "scale out," deploying large numbers of virtual Linux servers to provide high levels of service while, at the same time, helping reduce expense and complexity.
However, there is more to the operation of a modern data center than fiscal prudence. e-business operations have to also match customer habits. That can require 24 by 7 availability. Again, the IBM mainframe and Linux combine to deliver what businesses need to be: responsive, flexible and economical, without sacrificing resiliency.
Linux is widely accepted as a server operating system because of its high quality and stability. The IBM System z mainframe provide its legendary reliability, availability, security, scalability and autonomic attributes to any of the operating systems that run on it, and Linux is no exception. Add to this a complete and comprehensive suite of virtualization function which provides for virtual failover, elimination of single points of failure, regulation and control of servers and much more.
One of the keys to being responsive is simplicity. Keeping existing applications up and running and supplied with the latest data and updates requires a maintenance methodology that's simple, direct and easily managed. The IBM System z mainframe effectively provides those capabilities through virtualization. The ability to respond rapidly by quickly creating and provisioning new servers is a traditional z/VM strength. Populating these servers with useful applications is a great strength of Linux. A
wide range of applications from Independent Software Vendors as well as the Open Source community is available for deployment on System z mainframes running Linux.
Linux on System z can help you build an open, robust and scalable platform for your applications. The wide range of hardware and software supported on Linux have made it a favorite environment for developers and customers around the world.
