A ibm z890 mainframe for the midsized enterprise The wave of change that IBM first called “on demand” continues to gain momentum. Customers ask more of your company every day, demanding that your technology infrastructure be responsive, flexible and resilient. To help meet the challenges of constant
change, your company must do more than simply integrate its processes—it must literally be able to provide products and services to customers on demand. Achieving success in this environment requires an entirely new approach. In short, it’s never been so important for your business—and your
IT infrastructure—to be flexible.

How can the IBM z890 help you control costs?

This new line of highperformance midrange servers provides many of the capabilities available in larger enterprise-class servers at a lower entry point, along with extremely granular growth options that allow you to buy the capacity that best fits your needs. The ibm z890 is capable of running Linux and mainframe operating systems at the same time, and it provides the flexibility to easily manage changing business needs while maintaining mainframe levels of availability and security. With the ibm z890, you can start at the
capacity setting you need to meet your IT infrastructure requirements, then easily add additional capacity to meet your changing needs as you grow. The four processors on the z890 have seven engine levels, giving you a total of 28 capacity settings overall. The smallest IBM z890—with capacity setting 110—has most of the same features as the other 27 capacity settings, however, it has smaller I/O configuration/expansion capabilities.

Granular growth options


When it comes to growth, the ibm z890 offers extreme granularity. The range of capacities for the ibm z890 has increased from the processor on its predecessor, the IBM _`zSeries 800 (z800)— options for low capacity are now lower and those for high capacity are now higher. What does that mean to your business? It means you can start at the capacity level you need to simplify your IT infrastructure, then add additional capacity to meet your changing needs as you grow.

Built on ibm z990 technology

Built on the powerhouse function of the z990, the ibm z890 offers many of the features and functions of the z990 at a considerably lower capacity entry point. That’s not so bad, considering the z990 is IBM’s most sophisticated mainframe, with world-class scalability, virtualization, automation, security and reliability connection for configuration changes. Use of the OSA-ICC can positively impact the ongoing costs of running your system by eliminating the requirement for an external controller for console support.

What is zSeries server


The zSeries is the enterprise-class on demand server optimized for integration, transactions and data of the next generation on demand business world. In implementing the z/Architecture features with new technology solutions, zSeries models are designed to help facilitate the IT business transformation and reduce the stress of business-tobusiness and business-to-customer growth pressure. The zSeries represents an advanced generation of servers that feature enhanced performance, support for zSeries Parallel Sysplex® clustering, and improved hardware management controls and innovative functions to address on demand processing. The ibm z890 may be configured with an Internal Coupling Facility processor that can be integrated with other central processors or configured standalone to allow the ibm z890 to run as a Coupling Facility.
