  • Acrobat Distiller, Job 2
    A BRIEF HISTORY OF THE IBM ES/9000, SYSTEM/390 AND zSERIES 1990 IBM makes its most comprehensive product announcement in 25 years by introducing the System/390 family consisting of 18 Enterprise System/9000 processors ranging from midrange computers for office environments to the most powerful computers IBM has ever offered. Featuring enhanced function and capability to manage information systems, the System/390 provides increased processing power, better network management, improved communication among multivendor systems and the Enterprise System/9000 processors. In many cases, customers currently using IBM Enterprise System/3090 systems can easily upgrade their systems to System/390 processors. Other 1990 announcements include: several networking products to make it easier for customers to use their midrange, desktop and System/390 computers to communicate with non-IBM computers. 1991 IBM unveils seven new Enterprise System/9000 processors and operating system software — Advanced Interactive Executive/Enterprise System Architecture (AIX/ESA) — for the System/390 family. AIX/ESA is a further step in IBM’s implementation of open-systems computing across its product line and is based on UNIX and the Open Software Foundation’s OSF/1 standards. The company begins shipping in volume and on schedule two top-of-the-line ES/9000 models that were announced in September 1990. IBM Japan says it will supply Enterprise System/9000 processors and operating system software to Mitsubishi Electric Corp. for remarketing. The agreement marks the first time IBM has sold large processors as an original equipment manufacturer for resale. 1992 IBM introduces two entry-level Enterprise System/9000 processors and ships five new Enterprise System/9000 water-cooled processors — Models 520, 640, 660, 740 and 860 — one-to-four months ahead of schedule.

  • Rising IBM Mainframe Software Costs
    Rising IBM Mainframe Software Costs By Kim A. Eckert, Certified IT Architect Rising IBM mainframe software costs started getting the attention of high level executives some years ago. This was partially due to realizing the software inventories analysis was inefficient and limited. In addition, a third party company was hired to review IBM Strategic Outsourcing (SO) account’s inventory. In other words, IBM was paying "green" dollars to save "blue" dollars! In order for the team to become competitive and provide extra value to our Integrated Technology Delivery (ITD) accounts, I architected an automated system that merged data from several sources and made it easy for the technical support teams to verify the inventory. Once the reports were produced, my team would analyze the data and make recommendations for cost take out opportunities. There were several issues surrounding software licensing and validation: 1. IBM only had tools that would report on what was installed on a customer’s machine then that output would be matched up to what was actually licensed. This approach had benefits as in ensuring they are paying for what they use, but did not do the opposite - ensuring they are actually using what they are paying for. 2. The only place to find where a product was superseded by another was either Announcement letters or the Dawn report web page. The Dawn report lists all monthly license type software and their replacement if available. For example, it would show 5647-A01 OS/390 is replaced by 5694-A01 z/OS. 3. End of Support information was only available through Announcement letters or the Lifecycle Support web page.

  • Audit Report No.: 2007-DP-0004
    Issue Date February 22, 2007 Audit Report Number 2007-DP-0004 TO: Lisa Schlosser, Chief Information Officer, Q Joseph A. Neurauter, Chief Procurement Officer, N Keith A. Nelson, Assistant Secretary, Administration, A FROM: Hanh Do, Director, Information Systems Audit Division, GAA SUBJECT: Fiscal Year 2006 Review of Information Systems Controls in Support of the Financial Statements Audit HIGHLIGHTS What We Audited and Why We reviewed general and application controls for selected information systems to assess management controls over HUD’s computing environments as part of the Office of Inspector General’s (OIG) audit of the U.S. Department of Housing and Urban Development’s (HUD) financial statements for fiscal year 2006 under the Chief Financial Officer’s Act of 1990. What We Found HUD did not ensure that its general and application controls over its financial systems conformed to federal requirements and guidelines. Proper configuration management controls for software and document changes are not always employed, and access controls and support for the IBM mainframe operating system console are inadequate. Physical security controls over computing operations facilities are weak, and personnel security practices continue to pose the risk of unauthorized access to HUD systems. As a result, HUD’s financial systems are at risk of compromise. What We Recommend We recommend that the chief information officer, chief procurement officer, and assistant secretary for the Office of Administration ensure that Office of Management and Budget requirements, Federal Information Security Management Act requirements, National Institute of Standards and Technology guidelines, and HUD’s own internal policies and procedures are implemented. For each recommendation without a management decision, please respond and provide status reports in accordance with HUD Handbook 2000.06, REV-3.

  • Mainframe Hardware Course: Mainframe’S Processors
    Mainframe hardware course: Mainframe’s processors z/OS Basic Skills: The mainframe’s processors Mainframe’s processors This hardware course introduces you to one model of IBM® mainframe computer, the IBM System z9™, to help you learn about the hardware parts that constitute the mainframe’s processor by comparing processing parts and functions to personal computers or notebooks. Time to complete: 10 - 15 minutes ¾The central processor complex ¾The multichip module ¾Memory cards ¾Input/output connections ¾The mainframe’s processing capacity © Copyright IBM Corp. 2006. All rights reserved. The central processor complex z/OS Basic Skills: The mainframe’s processors Mainframe’s processors > The central processor complex Mainframes have one or two metal frames that contain specialized cages, as well as other physical elements. This diagram shows the interior front view of an IBM System z9 Enterprise Class (z9 EC) model that has two frames. The z9 EC is slightly larger than a household refrigerator. The central processor complex, or CPC, resides in its own cage inside the mainframe, and consists of one to four book packages. Just like its personal-computer counterpart, the motherboard or system board, each book package consists of processors, memory, timers, and I/O connections. These collections of hardware parts are called “book packages” because you can slide them in or out of the CPC cage almost as easily as you can slide a book on or off a bookshelf. © Copyright IBM Corp. 2006. All rights reserved. z/OS Basic Skills: The mainframe’s processors Mainframe’s processors > The book package In the System z9, as well as earlier IBM mainframe models, the book package consists of three distinct areas, one each for: • The z9 EC's processors, which are inside one multichip module • Memory cards • Connections to input/output devices All of the book packages plug into a backplane in the z9 EC's frame.

Some CIOs may think it’s time to retire their IBM Z® mainframe. They may think the technology has become outdated, they may not understand the full benefits they provide, or both. The mainframe has design strengths that, today, make it invaluable to IT organizations for hosting their most important, mission-critical applications. These applications typically include customer order processing, financial transactions, production and inventory control, payroll, as well as many other types of computationally intensive and high-volume tasks. This whitepaper demonstrates why IBM Z mainframes are the best choice to be the bedrock for critical, “can’t fail” processing tasks, and why, over the long term, they deliver among the best value in the IT ecosystem. Whitepaper The Rockstar in Your Data Center: The IBM Z Mainframe BACK TO TABLE OF CONTENTS ROCKETSOFTWARE.COM 3 Key takeaways Don’t automatically dismiss IBM Z when making strategic decisions about your current and future IT environment. It continues to have significant market and competitive strength, and IBM makes sure it works with the latest technologies, including cloud computing and open-source tools. It’s a key innovation player that drives better ROI on core infrastructure while supporting the latest advancements in technology and user experience. The at-risk platform in large organization data centers is not the mainframe.
