PREVIEW IBM z/OS V2.1 and IBM z/OS Management Facility Version 2.1

z/OS V2.1 is designed to help you run your business with smarter computing. New z/OS capabilities outlined in this preview are intended to drive efficiency at scale and improve availability; accelerate high performance data serving and batch to help with analytics; and provide an ultimate security ready infrastructure with new cryptography, management and standards enhancements. The preview of z/OSMF V2.1 describes how it can help you more efficiently manage your z/OS software environment with ease, simplify configuration, and improve usability, all using a lightweight footprint.

Announcing New Statement of Direction for z/OS

IBM plans to introduce a new version of the z/OS operating system, z/OS Version 2, to be released in the second half of 2013 as part of a new two-year release cycle. This improved release schedule is intended to provide you with sufficient time to plan for releases and leverage them for the most business value. As part of the new release schedule, IBM plans to provide five years of z/OS support, with three years of optional fee-based extended service following the end of support for the release. In z/OS V2.1, IBM also plans to further leverage enhancements in the current IBM mainframe servers and storage control units. Please see SOD for more details.

z/OS Version 1 Release 13

This latest release of z/OS brings a new dimension to system availability, application development, and performance. It can help you get early warning of certain system issues before they become obvious to help you act quickly and decisively with integration between z/OS Predictive Failure Analysis and Runtime Diagnostics functions. This latest release delivers enhancements designed to help shorten your batch window, simplify batch programming, and give you more flexibility in deploying batch applications. z/OS V1.13 also delivers improved performance for web-based applications with better overall I/O response times for z/OS UNIX System Services workloads in a Parallel Sysplex, as well as improved performance for traditional workloads using the IEBCOPY utility to copy one PDS (partitioned data set) to another.

z/OS Management Facility V1.13

IBM z/OS Management Facility (5655-S28) is the new face of z/OS. It is a modern management console for z/OS and is intended to enable system programmers to more easily manage and administer a mainframe system by simplifying day to day operations and administration of a z/OS system. z/OSMF V1.13 introduces new system management tasks which can clone z/OS images and deploy software more easily and consistently, and support easier monitoring of z/OS Capacity Provisioning functions. Existing tasks are updated and improve your ability to manage incident log data, network security configuration, and cross-platform resource monitoring. This release also creates a more unified z/OS experience with a new web-enabled ISPF interface, and the ability to link and launch between z/OSMF and other browser-accessible applications.

 

Linux on System z

Show descriptions | Hide descriptions

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 optimization and simplification of the IT infrastructure. It offers an infrastructure that is ready for consolidation, re-deployment and new workload deployments for the new era we call Smarter Computing.


Featured topic

Increased economics for optimized workload deployments

The Linux environment benefits from the enormous improvements of the IBM zEnterprise EC12, as well as from the IBM zEnterprise 114 and the IBM zEnterprise 196 server capabilities for optimized workload deployments, especially in the areas of consolidation, security and reliability.
You can run up to thousands of virtual Linux servers concurrently, with ensured isolation and protection of each virtual server environment. You can consolidate and deploy new workloads on one single System z server, which may result in software license savings, management effort savings, floor space and energy savings. You can optimize your workloads by "doing more with less".

Lower your monthly costs

Improve IT economics and drive greater performance 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 optimized workload deployments and large scale consolidations that can dramatically reduce  the cost of software licenses, and can help you to drive operational efficiency and floor space savings.

z/VM

Show descriptions | Hide descriptions

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.

z/VM® 40th Anniversary - August 2, 2012

Forty years ago, on August 2, 1972, commercial use of virtualization became a reality with the IBM announcement of VM/370.  Virtualization has transformed the way we think about the underlying technology by providing flexible dynamic server resources that help businesses run faster and respond to customer needs more efficiently.   z/VM is built on design points that have stood the test of time and remain essential to our customers today.

z/VM 6.2 - Accelerating the Journey to Smarter Computing

The highlight of the z/VM 6.2 release is Multi-system virtualization which clusters z/VM instances and helps clients in multiple ways. It offers a more manageable infrastructure for cloud computing by providing a set of shared resources that can be managed as a single resource pool. It also provides the ability to move Linux virtual servers without disruption across the System z family, between IBM System z10 EC, z10 BC, z196, and z114 servers. This support provides flexible workload balancing and reduces the impact of planned outages. Now clients will be able to plan outages on their timeline and move work to available  resources in addition to the long standing capability to move system resources to work.

 

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
