There are 405,535 employees and 798,152 stockholders at year-end. Organization IBM President John F. Akers succeeds John R. Opel as chief executive officer, effective February 1. Mr. Akers also is to head the Corporate Management Board and serve as chairman of its Policy Committee and Business Operations Committee. PC dealer sales, support and operations are transferred from the Entry Systems Division (ESD) to the National Distribution Division, while the marketing function for IBM’s Personal Computer continues to be an ESD responsibility. IBM announces in September a reorganization of its U.S. marketing operations. Under the realignment, to take effect on Jan. 1, 1986, the National Accounts Division, which markets IBM products to the company’s largest customers, and the National Marketing Division, which serves primarily medium-sized and small customer accounts, are reorganized into two geographic marketing divisions: The North-Central Marketing Division and the South-West Marketing Division. The National Distribution Division, which directs IBM’s marketing efforts through Product Centers, value-added remarketers, and authorized dealers, is to merge its distribution channels, personal computer dealer operations and systems supplies field sales forces into a single sales organization. The National Service Division is to realign its field service operations to be symmetrical with the new marketing organizations.

  • Using IBM System Z As the Foundation for Your Information Management Architecture
    Front cover Using IBM System z As the Foundation for Your Information Management Architecture Redguides for Business Leaders Alex Louwe Kooijmans Willie Favero Fabricio Pimentel Information management challenges Strengths of IBM System z for information management Exploring the IBM Smart Analytics Optimizer for DB2 for z/OS V1.1 Executive overview Many companies have built data warehouses (DWs) and have embraced business intelligence (BI) and analytics solutions. Even as companies have accumulated huge amounts of data, however, it remains difficult to provide trusted information at the right time and in the right place. The amount of data collected and available throughout the enterprise continues to grow even as the complexity and urgency of receiving meaningful information continues to increase. Producing meaningful and trusted information when it is needed can only be achieved by having an adequate information architecture in place and a powerful underlying infrastructure. The amounts of data to mine, cleanse, and integrate are becoming so large that increasingly the infrastructure is becoming the bottleneck. This results in low refresh rates of the data in the data warehouse and in not having the information available in time where it is needed. And even before information can become available in a BI dashboard or a report, many preceding steps must take place: the collection of raw data; integration of data from multiple data stores, business units or geographies; transformation of data from one format to another; cubing data into data cubes; and finally, loading changes to data in the data warehouse. Combining the complexity of the information requirements, the growing amounts of data, and multiple layers of the information architecture requires an extremely powerful infrastructure.

The use of this information or the implementation of any of these techniques is a customer responsibility and depends on the customer's ability to evaluate and inte­ grate them into the customer's operational environment. While each item may have been reviewed by IBM for accuracy in a specific situation, there· is no guarantee that the same or similar results will be obtained elsewhere. Customers attempting to adapt these techniques to their own environments do so at their own ris.k. Reference to PTF numbers that have not been released through the PUT process does not imply general availability. The purpose of including these reference numbers is to alert IBM CPU customers to specific information relative to the implementation of the PTF when it becomes available to each customer according to the normal IBM PTF distribution rules. Performance data contained in this document was determined in a controlled environ­ ment; and therefore, the results which may be obtained in other operating environ­ ments may vary significantly. Users of this document should verify the applicable data for their specific environment.

  • IBM Zenterprise Redundant Array of Independent Memory Subsystem
    IBM zEnterprise redundant P. J. Meaney L. A. Lastras-Montan˜o array of independent V. K. Papazova E. Stephens memory subsystem J. S. Johnson L. C. Alves A The IBM zEnterprise system introduced a new and innovative J. A. O’Connor redundant array of independent memory (RAIM) subsystem design as W. J. Clarke a standard feature on all zEnterprise servers. It protects the server from single-channel errors such as sudden control, bus, buffer, and massive dynamic RAM (DRAM) failures, thus achieving the highest System zA memory availability. This system also introduced innovations such as DRAM and channel marking, as well as a novel dynamic cyclic redundancy code channel marking. This paper describes this RAIM subsystem and other reliability, availability, and serviceability features, including automatic channel error recovery; data and clock interface lane calibration, recovery, and repair; intermittent lane sparing; and specialty engines for maintenance, periodic calibration, power, and power-on controls. Introduction and other symbol-oriented codes have been used by IBM and The IBM zEnterprise* 196 (z196) represents a significant others to improve memory reliability. This more advanced leap forward in reliability and availability of the memory ECC technology is capable of detecting, isolating, and subsystem. This new memory design, combined with the correcting full memory chip failures and memory bus microprocessor and cache subsystem enhancements, achieves failures [2]. higher capacity, higher performance, and higher reliability, In addition to ECC, other techniques have been used to compared with previous designs [1]. improve memory reliability. For instance, scrubbing was Memory size and density have continued to increase added to periodically read and write memory to correct substantially as computer systems have become more soft errors.
