VM2000

Last updated

VM 2000 is a hypervisor from Fujitsu (formerly Siemens Nixdorf Informationssysteme) designed specifically for use with the BS2000 operating system. It is an EBCDIC-based operating system. It allows multiple images of BS2000 and Linux [1] to operate on a S-series computer, which is based on the IBM System/390 architecture. It also supports BS2000, Linux and Microsoft Windows on x86-based SQ-series mainframes. [2] Additionally, it can virtualize BS2000 guests on SR- and SX-series mainframes, based on MIPS and SPARC respectively. [3] [4]

A hypervisor or virtual machine monitor (VMM) is computer software, firmware or hardware that creates and runs virtual machines. A computer on which a hypervisor runs one or more virtual machines is called a host machine, and each virtual machine is called a guest machine. The hypervisor presents the guest operating systems with a virtual operating platform and manages the execution of the guest operating systems. Multiple instances of a variety of operating systems may share the virtualized hardware resources: for example, Linux, Windows, and macOS instances can all run on a single physical x86 machine. This contrasts with operating-system-level virtualization, where all instances must share a single kernel, though the guest operating systems can differ in user space, such as different Linux distributions with the same kernel.

IBM mainframes are large computer systems produced by IBM since 1952. During the 1960s and 1970s, IBM dominated the large computer market. Current mainframe computer in IBM's line of business computers are developments of the basic design of the IBM System/360.

Mainframe computer computers used primarily by corporate and governmental organizations

Mainframe computers or mainframes are computers used primarily by large organizations for critical applications; bulk data processing, such as census, industry and consumer statistics, enterprise resource planning; and transaction processing. They are larger and have more processing power than some other classes of computers: minicomputers, servers, workstations, and personal computers.

z/VSE is an operating system for IBM mainframe computers, the latest one in the DOS/360 lineage, which originated in 1965. Announced Feb. 1, 2005 by IBM as successor to VSA/ESA 2.7, then-new z/VSEwas named to reflect the new "System z" branding for IBM's mainframe product line.

Hercules (emulator) computer emulator

Hercules is a computer emulator allowing software written for IBM mainframe computers and for plug compatible mainframes to run on other types of computer hardware, notably on low-cost personal computers. Development started in 1999 by Roger Bowler, a mainframe systems programmer.

A computing platform or digital platform is the environment in which a piece of software is executed. It may be the hardware or the operating system (OS), even a web browser and associated application programming interfaces, or other underlying software, as long as the program code is executed with it. Computing platforms have different abstraction levels, including a computer architecture, an OS, or runtime libraries. A computing platform is the stage on which computer programs can run.

BS2000 is a mainframe computer operating system developed in the 1970s by Siemens and from early 2000s onward by Fujitsu Technology Solutions.

This article presents a timeline of events in the history of computer operating systems from 1951 to the current day. For a narrative explaining the overall developments, see the History of operating systems.

VM (operating system) family of IBM virtual machine operating systems

VM is a family of IBM virtual machine operating systems used on IBM mainframes System/370, System/390, zSeries, System z and compatible systems, including the Hercules emulator for personal computers.

The Integrated Facility for Linux (IFL) is an IBM mainframe and Power Systems processor dedicated to running the Linux operating system. On System z, it can be used with or without z/VM. IFLs are one of three types of IBM mainframe processors expressly designed to reduce software costs.. Microcode restricts IFLs to Linux workload by omitting some processor instructions not used by the Linux kernel. As with zAAPs and zIIPs, IFLs are not specifically optimized to run Linux faster or better.

z/VM is the current version in IBM's VM family of virtual machine operating systems. z/VM was first released in October 2000 and remains in active use and development as of 2016. It is directly based on technology and concepts dating back to the 1960s, with IBM's CP/CMS on the IBM System/360-67. z/VM 6.4 runs on IBM's System z family of computers. It can be used to support large numbers (thousands) of Linux virtual machines.

Fujitsu Siemens Computers Japanese and German IT vendor

Fujitsu Siemens Computers GmbH was a Japanese and German vendor of Information technology. The company was founded in 1999 as a 50/50 joint venture between Fujitsu Limited of Japan and Siemens of Germany. On April 1, 2009, the company became Fujitsu Technology Solutions as a result of Fujitsu buying out Siemens' share of the company.

PowerLinux is the combination of a Linux-based operating system (OS) running on PowerPC- or Power ISA-based computers from IBM. It is often used in reference along with Linux on Power, and is also the name of several Linux-only IBM Power Systems.

A logical partition, commonly called an LPAR, is a subset of a computer's hardware resources, virtualized as a separate computer. In effect, a physical machine can be partitioned into multiple logical partitions, each hosting a separate instance of an operating system.

Since the rise of the personal computer in the 1980s, IBM and other vendors have created PC-based IBM-compatible mainframes which are compatible with the larger IBM mainframe computers. For a period of time PC-based mainframe-compatible systems had a lower price and did not require as much electricity or floor space. However, they sacrificed performance and were not as dependable as mainframe-class hardware. These products have been popular with mainframe developers, in education and training settings, for very small companies with non-critical processing, and in certain disaster relief roles.

IBM Z Family name used by IBM for its non-POWER mainframe computers from the Z900 on

IBM Z is a family name used by IBM for all of its non-POWER mainframe computers from the Z900 on. In July 2017, with another generation of products, the official family was changed to IBM Z from IBM z Systems; the IBM Z family now includes the newest model the IBM z14, as well as the z13, the IBM zEnterprise models, the IBM System z10 models, the IBM System z9 models and IBM eServer zSeries models.

Fujitsu Technology Solutions German company

Fujitsu Technology Solutions is a European information technology vendor with a presence in markets in Europe, the Middle East, Africa, as well as India. A subsidiary of Fujitsu Limited headquartered in Tokyo, Japan, FTS was founded in 2009 after Fujitsu bought out Siemens' 50% share of Fujitsu Siemens Computers.

IBM zEnterprise System A line of IBM mainframe computer systems

IBM zEnterprise System is the latest line of IBM mainframes designed to offer both mainframe and distributed server technologies in an integrated system. The zEnterprise System consists of three components. First is a System z server – a choice of the newest enterprise class server, the IBM zEnterprise EC12 that was announced August 28, 2012, the smaller business class server the IBM zEnterprise 114 (z114) announced July 2011, or the older enterprise-class server the IBM zEnterprise 196 (z196) that was introduced July 2010. Second is the IBM zEnterprise BladeCenter Extension (zBX), the infrastructure designed to provide logical integration and host IBM WebSphere DataPower Integrated Appliance XI50 for zEnterprise or general purpose x86 or Power ISA blades. Last is the management layer, IBM zEnterprise Unified Resource Manager (zManager), which provides a single management view of zEnterprise resources.

Linux on z Systems

Linux on IBM Z is the collective term for the Linux operating system compiled to run on IBM mainframes, especially IBM Z and IBM LinuxONE servers. Similar terms which imply the same meaning are Linux on zEnterprise, Linux on zSeries, Linux/390, Linux/390x, etc. The terms zLinux or z/Linux are also sometimes used, but these terms are discouraged by IBM as they create the implication of an IBM-offered or IBM-distributed version of Linux, which is incorrect.
