Operating systems

IBM z Systems mainframe servers support multiple operating systems including z/OS, z/VSE, z/TPF and Linux on z Systems in addition to the z/VM hypervisor.



z/OS

IBM z/OS® delivers innovations to help you build the highly scalable next-generation infrastructure you need to capture opportunities in the digital economy. IBM z/OS V2.2 offers leading scalability, resiliency, availability, and security to exceed response time objectives, to protect sensitive information and assets, and to innovate with new business applications. Now included, z/OSMF helps automate z/OS administration and management to extend the reach of your skills.

Featured topic: z/OS V2.2 announcement

The IBM z/OS V2.2 operating system and the latest IBM z13 server team to deliver innovations designed to help you build the next generation infrastructure for your digital business. z/OS V2.2 offers the scalability, availability, and security to improve business performance, meet response time requirements, protect sensitive data and transactions, and simplify management — all while delivering an exceptional customer experience. IBM z/OS V2.2 is designed to:

Linux on z Systems

The Linux environment benefits from the enormous capabilities of the IBM z Systems, IBM z/VM virtualization and IBM Wave for z/VM virtualization management technologies, providing an enterprise grade Linux platform for all kind of workloads - cloud, analytics, mobile, and much more – data center simplification, trusted operations and unrivaled economics. Benefits include:

Master IT complexity while improving economics and driving higher qualities of service with the Enterprise Linux Server. It can help you to reduce both cost of acquisition and cost of ownership. The Enterprise Linux Server can provide you the IT infrastructure for enterprise grade Linux deployments, including large scale consolidations that can dramatically reduce the cost of software licenses, and can help you to drive datacenter simplicity, trusted operations and unrivaled economics.

z/VM

The advanced virtualization technologies of the z/VM hypervisor combined with the highly attractive economics on the highly secure and reliable z Systems servers 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 z Systems operating systems for non-Linux workloads, such as z/OS®, z/VSE, and z/TPF on the same z Systems 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.

Featured topic: z/VM Version 6 Release 3

z/VM 6.3 is the premier virtualization platform. It supports more virtual servers than any other in a single footprint for growing business demands and lower cost of service delivery. With its high level of security, you can put your trust z/VM to protect your most valuable information and thereby reduce organizational and reputational risk. Benefits include:

z/Transaction Processing Facility (z/TPF)

Transaction processing is a largely invisible back-end business computing function. Yet it is a key enabler of an enormous range of economic activities – from travel reservation and ticketing systems and electronic banking, to financial transactions and e-commerce. Transaction processing is and will remain a critical component of the world’s economic engine – responsible for handling trillions of transactions every year. The workload volume managed by major users of transaction-processing systems is enormous. The majority of high volume transaction processing applications run on mainframes and rely on operating systems such as zTPF.

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 zEnterprise 196, 114, BC12, EC12 and z13 and IBM System Storage technology. z/VSE focuses on scalability, security, and hybrid solutions including Linux on z Systems. Learn more about z/VSE, z/Architecture, latest enhancements, and integration with Linux on z Systems.

Featured topic: IBMz/VSE V6.1

In 2015, z/VSE celebrates its fiftieth anniversary. In continuation of 50 years of innovation and evolution, IBM is pleased to preview z/VSE V6.1. Whereas the past z/VSE versions often addressed scalability and constraint relief, z/VSE V6.1 will now focus on online processing, security, and networking. To help clients protect their investments in online environments, z/VSE V6.1 delivers CICS Transaction Server (CICS TS) for z/VSE V2.1.
