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. -

Introducing Linux on IBM Z Systems IT Simplicity with an Enterprise Grade Linux Platform
Introducing Linux on IBM z Systems IT simplicity with an enterprise grade Linux platform Wilhelm Mild IBM Executive IT Architect for Mobile, z Systems and Linux © 2016 IBM Corporation IBM Germany What is Linux? . Linux is an operating system – Operating systems are tools which enable computers to function as multi-user, multitasking, and multiprocessing servers. – Linux is typically delivered in a Distribution with many useful tools and Open Source components. Linux is hardware agnostic by design – Linux runs on multiple hardware architectures which means Linux skills are platform independent. Linux is modular and built to coexist with other operating systems – Businesses are using Linux today. More and more businesses proceed with an evolutionary solution strategy based on Linux. 2 © 2016 IBM Corporation What is IBM z Systems ? . IBM z Systems is the family name used by IBM for its mainframe computers – The z Systems families were named for their availability – z stands for zero downtime. The systems are built with spare components capable of hot failovers to ensure continuous operations. IBM z Systems paradigm – The IBM z Systems family maintains full backward compatibility. In effect, current systems are the direct, lineal descendants of System/360, built in 1964, and the System/370 from the 1970s. Many applications written for these systems can still run unmodified on the newest z Systems over five decades later. IBM z Systems variety of Operating Systems – There are different traditional Operating Systems that run on z Systems like z/OS, z/VSE or TPF. With z/VM IBM delivers a mature Hypervisor to virtualize the operating systems. -

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.
