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.


Increased economics for Linux workload deployments

The Linux environment benefits from the enormous capabilities of the IBM zEnterprise servers, the IBM z/VM virtualization and the new virtalization management IBM Wave for z/VM software capabilities for IT optimization, especially in the areas of consolidation, security and cloud computing.

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. Its strength to run a large number of parallel workloads in a highly efficient and economical way is improved into new dimensions.

Master IT complexity while improving economics and driving 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 enterprise-class 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 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 Version 6 Release 3 - Virtualization with Efficiency at Scale

Advanced z/VM virtualization features help provide a highly secure and scalable infrastructure and an environment capable of running multiple diverse critical applications at the same time. With support for more virtual servers than any other platform in a single footprint, z/VM supports workloads that scale horizontally and vertically at a low total cost of ownership, creating an environment suitable for a private cloud. z/VM V6.3 and IBM Wave for z/VM extend System z's virtualization capabilities even further by offering:

  • Improved economies of scale with support for 1TB of real memory
  • More efficient use of CPU resources for improved price performance
  • Simplified migration with reduced impact on active workloads
  • Highly secure industry standard support required for banking and financial-industry applications
  • Support for OpenStack enables z/VM to be managed with open cloud architecture-based interfaces
  • New! IBM Wave for z/VM helps improve, simplify and automate management of a virtual Linux servers

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
