Linux on zSeries

Linux and zSeries are a great team. Linux has the same appearance and application programming interfaces no matter what platform it is running on, since it is designed to be platform-independent. When Linux is run on a zSeries server it inherits the legendary qualities of service that businesses world-wide rely on for hosting their most important workloads. Linux is open standards-based, sup- porting rapid application portability and can be adapted to suit changing business needs. The fl exibility and open- ness of Linux make it very popular with developers, whose contributions endow Linux with an extensive and diverse application portfolio. zSeries servers enable massive scal- ability within a single server, either horizontally or vertically. Hundreds of Linux images can run simultaneously, provid- ing unique server consolidation capabilities while aiding in reducing both cost and complexity.

Of course, no matter which Linux applications are brought to the zSeries platform, they can all benefi t from high- speed access to the applications and corporate data that reside on zSeries.

IBM developed the code that enables Linux to run on zSeries servers, and made it available to the Open Source community. The term used to describe this enabling code is “patches.”

To help eliminate the need for an external 2074 Console controller and associated consoles, an administrator may utilize the Hardware Management Console (HMC) func- tions “Integrated 3270 Console Support” for operating z/VM images, and “Integrated ASCII Console Support” to operate Linux images.
