    The Changing Face of Below 60-MIPS Mainframes

    Moore's law, most visibly observed in PCs and servers, has also quietly transformed the mainframe world. Its stellar price/performance consequence has reduced the ability of companies like IBM to provide labor-intensive services such as on-site sales and support; it also imposes economic disincentives to offer small machines, since they cost as much as large systems to build and support—yet market forces dictate that they sell cheaper and thus cannot carry overhead and staffing burdens enjoyed in the past.

    IBM Mainframe Partitioning: LPAR vs. VM Function and Efficiency

    IBM mainframe computers (System/390, zSeries 900 systems) are commonly partitioned to improve reliability and operational efficiency. Partitioning creates multiple system images that can perform related or unrelated work, using homogenous or heterogeneous operating system environments.

  • Technology Trends - Why, Whether, When to Migrate from VSE to z/OS—Cost/Benefit Tradeoffs

    Why, Whether, When to Migrate from VSE to z/OS—Cost/Benefit Tradeoffs

    Many VSE sites maintain a "steady as we go" attitude, focusing on incrementally growing application requirements. Evolving application needs can often be satisfied by upgrading within VSE, partnering Linux capabilities with VSE, or installing a small VSE-connected Unix/HP/NT system. These choices can be online faster and cost much less than undertaking z/OS migration, which typically requires 15-18 months and costs a million dollars.

    z/VM—What’s Old Is New Again for Mainframe Productivity

    Today's z/VM, Version 4.2, has a noble decades-long lineage, but has hardly grown stale; it plays an up-to-the-minute role in bringing enterprise-class services to diverse market sectors, often enabling mission-critical Internet services.
