IBM pioneered the concept of introduced recently for the mainframe market? virtual storage on S/370 in the early ’70s. The famous August 1972 IBM System/370 Advanced Function announcement Carney: We’ve introduced several enhancements in introduced four new IBM mainframe operating systems: our Fibre Channel operating system known as FOS, or DOS/VS (DOS with virtual storage), OS/VS1 (OS/MFT with Fabric OS. There are several more currently undergoing virtual storage), OS/VS2 (OS/MVT with virtual storage, qualification at IBM Poughkeepsie with our latest operating which would grow into SVS and MVS) and VM/370. system release (FOS 7.1). For example, we’ve added some Multiple Virtual Storage (MVS) is still with us in the form of enhanced diagnostics features to FICON CUP that will z/OS. The concept of virtual machines has been around for allow for integration of our FICON directors with the IBM more than 40 years now, thanks to the IBM mainframe. As z/OS Health Check functionality. We made some significant far as cloud computing goes, thanks to that pioneering work enhancements to our FOS Extended Fabrics feature that will in virtualization, the IBM mainframe and today’s System z simplify buffer credit management for applications such as were clouds before cloud was a word. Few people realize that multisite Disaster Recovery (DR). We’ve also recently the first Storage Area Network (SAN) was ESCON. And as introduced some exciting, new technologies that will allow far as SDN goes, I think the modern System z led the way customers to more efficiently utilize their cross-site with the z/OS Communications Server. bandwidth, as bandwidth between sites is the most expensive cost in any DR architecture.

Carney: Brocade is a customer-centric company.

However, the reader should have a basic understanding of I BM data processing. VM/370 (Virtual Machine Facility/370) is a system control program (SCP) that tailors the resources and capabilities of a single System/370 computer to provide concurrent users their one unique (virtual) machine. VM/370 consists of a Control Program (CP), which manages the real computer, a Conversational Monitor System (CMS), which is a general-purpose conversational time-sharing system that executes in a virtual machine, a Remote Spooling Communications Subsystem (RSCS), which spools files to and from geographically remote locations, and a Interactive Problem Control System (I PCS), which provides problem analysis and management faci I ities. The first section of the publication is an introduction; it describes what VM/370 can do. The second, third, fourth, and fifth sections describe the Control Program, Conversational Monitor System, Remote Spooling Communications Subsystem, and Interactive Problem Control System respectively. The appendixes include information about VM/370 publication-to-audience relationship and VM/370-related publications for CMS users. , This publication is a prerequisite for the VM/370 system library. --...- --- ---.-- ------- ------ --..- --------- -~-y- Page of GC20-1800-9 As Updated Aug 1, 1979 by TNL GN25-0U89 ~b Edition (Karch 1919) This edition (GC20-1800-~ together with Technical Newsletter GN25-0489. dated August 1, 1919, applies to Release 6 PLC 4 (Program Level Change) of IBM Virtual Machine Facility/310 and to all subsequent releases until otherwise indicated in new editions or Technical Newsletters.

  • 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.
