IBM System z servers are supported by a multitude of operating systems, such as z/OS, z/VSE, z/TPF, Linux on System z and the z/VM hypervisor.
z/OS
Now more than ever IBM System z® and z/OS® are the right choice for your infrastructure and workload needs. The epitome of investment protection, z/OS goes to great lengths to keep applications and data available, system resources secure, server utilization high, and programming environments adaptable while maintaining compatibility for existing applications. You have neither the time nor the resource to spend on "throw away" solutions, "rip and replace" systems, or yet another technology trend. The smart, adaptive technologies of z/OS can provide a secure, resilient, and Dynamic Infrastructure that integrates business needs and IT capabilities. Work smarter with z/OS.

Previewing z/OS Version 1 Release 12
IBM heralds a new direction of smart operating systems, creating an environment that can proactively work for you to help promote improved operations, availability, and manageability through innovative self-learning, self-managing, and self-optimization capabilities. New designs planned for z/OS Predictive Failure Analysis, z/OS Runtime Diagnostics, Parallel Sysplex autonomics, and CA (Control Area) Reclaim can help provide the ability to discover, decide and resolve issues in a fraction of the time can keep your organization nimble and responsive to changing business needs.
Linux on System z
Linux on System z combines the advantages of the IBM mainframes with the flexibility and open standards of the Linux operating systems. Linux can play a major role in the simplification of the IT infrastructure—not only because it helps simplify business integration through the use of open and industry standards, but also because it supports deployment of new solutions more quickly and accelerates time to market.

An Approach to Meeting Your Goals
The IBM Enterprise Linux® Server is providing a scalable and flexible virtual infrastructure, customized for server virtualization and workload consolidation inside a single IBM server. This infrastructure is designed for today’s instrumented, interconnected and intelligent world, transforming virtualization into higher qualities.
z/VM
The advanced virtualization technologies available with the z/VM hypervisor combined with the highly attractive economics on the highly secure and reliable System z10 servers are designed to help clients extend the business value of mainframe technology across the enterprise by integrating applications and data while providing exceptional levels of availability, security, and operational ease. z/VM virtualization technology is designed to allow the capability for clients to run hundreds to thousands of Linux servers as z/VM guests in a single mainframe while hosting other System z operating systems for non-Linux workloads, such as z/OS®, z/VSE, and z/TPF on the same System z server or as a large-scale Linux-only enterprise server solution. The proven capabilities of z/VM can help provide Linux guests with the mainframe's powerful resources.

Free trial: z/VM Version 5.3 Evaluation Edition available
IBM has made the zVM V5.3 Evaluation Edition available, a free trial version of z/VM V5.3 that is intended to provide all IBM System z10 clients the opportunity to evaluate z/VM. This no-charge license allows new z/VM clients to familiarize themselves with z/VM virtualization technology on the System z10 EC or z10 BC server. The z/VM Evaluation Edition can be used for proofs-of-concept and to also evaluate the effectiveness and robustness of z/VM as well as it's many capabilities.
z/TPF
z/TPF remains the "high volume transaction processing" (HVTP) platform of choice for many of IBM's largest customers for many years. These customers cover several industries, including airlines, lodging, finance, health, and travel.
z/VSE
z/VSE is designed to help clients protect their investments into VSE applications and data. It addresses requirements for growing z/VSE workloads and consolidation of z/VSE systems, exploiting innovative IBM System z10 and IBM System Storage technology. z/VSE focuses on scalability, security, and hybrid solutions including Linux on System z. Learn more about z/VSE, z/Architecture, latest enhancements, and integration with Linux on System z.

Previewing z/VSE Version 4 Release 3
IBM announced a preview of z/VSE Version 4 Release 3 (V4.3), the newest version of z/VSE providing more capacity for future growth. z/VSE V4.3 is designed to offer virtual storage constraint relief for CICS workload growth and system consolidation. It will exploit selected IBM System z10 technology, including large page support, FICON Express8, and the ability to dynamically add logical CPs without preplanning. Four-digit device addresses provide for infrastructure simplification in mixed IT environments consisting of z/VSE, z/VM, Linux on System z, and/or z/OS. Further enhancements apply to networking, security, and systems management, as well as RPG II compiler support for CICS TS. A statement of direction* announces that z/VSE V4.3 intends to provide an IPv6 solution.
