Overview of Mainframe

  • Mainframes can add or hot swap system capacity without disrupting system function, with specificity and granularity to a level of sophistication not usually available with most server solutions.[citation needed] Modern mainframes, notably the IBM zSeries, System z9 and System z10 servers, offer two levels of virtualization: logical partitions (LPARs, via the PR/SM facility) and virtual machines (via the z/VM operating system).
  • Mainframes have a fewthing called “five nines” availability which means that a mainframe’s “up time” factor is 0.99999 or put in plain English, a mainframe can run non-stop 24x7x365 supporting thousands of simultaneous users for a full year and can reliably be counted on to not be “down” for more than about 5 minutes total for the year.
  • Mainframe is made up of several multiprocessors, vector processors and Massivelly Processors(MPP) connected thru very large scale interconnected bus has the capability to process mulit-processing fuctions and to having RAM and ROM having much capibility to send and receive the Data at much hi speed.
  • Mainframe return on investment (ROI), like any other computing platform, is dependent on its ability to scale, support mixed workloads, reduce labor costs, deliver uninterrupted service for critical business applications, and several other risk-adjusted cost factors.
  • Mainframe computers are powerful computers that can handle vast quantities of data and offer highly stable transaction processing (a transaction is a discrete computer operation that must be completed in its entirety and cannot be sub divided into separate tasks).
  • The mainframe is more powerful and more secure than ever before, and it’s the technology for supporting analytics, application management, blockchain, machine virtualization, cloud, containerization and cryptography that are all vital to thrive in today’s economy.
  • Mainframe as-a-Service is an alternative that re-orients existing legacy mainframe systems infrastructure – compute, storage and networking – and allows operators to scale mainframe capacity in alignment with their organization’s unique requirements.
  • Mainframe compatibility options in products like Microfocus COBOL and Gnu COBOL don’t produce zOS-ready load modules; they provide source-level compatibility, so you can transfer the source code back and forth without any modifications.
  • Mainframe is the Joe soldier who discovers that Cobra exists as an organization in the first place; his theories that they are a group willing to profit in the long term pans out.
  • Mainframe and Dusty are sent in to locate a Cobra Terror Drome launch base hidden in the country after spy satellites detect the base’s infrared signature.
  • Network

    8,000 virtual machines on a single mainframe.Another factor currently increasing mainframe use is the development of the Linux operating system, which arrived on IBM mainframe systems in 1999 and is typically run in scores or up to c.Batch processing, such as billing, became even more important (and larger) with the growth of e-business, and mainframes are particularly adept at large-scale batch computing.But MIPS (millions of instructions per second) shipments increased 4% per year over the past two years.[18] Alsop had himself photographed in 2000, symbolically eating his own words (“death of the mainframe”).[19]
    For example, in the 4th quarter of 2009, IBM’s System z hardware revenues decreased by 27% year over year.However, IBM’s mainframe hardware business has not been immune to the recent overall downturn in the server hardware market or to model cycle effects.IBM’s quarterly and annual reports in the 2000s usually reported increasing mainframe revenues and capacity shipments.Linux allows users to take advantage of open source software combined with mainframe hardware RAS.providing unified, extremely high volume online transaction processing databases for 1 billion consumers across multiple industries (banking, insurance, credit reporting, government services, etc.) In late 2000, IBM introduced 64-bit z/Architecture, acquired numerous software companies such as Cognos and introduced those software products to the mainframe.Rapid expansion and development in emerging markets, particularly People’s Republic of China, is also spurring major mainframe investments to solve exceptionally difficult computing problems, e.g.That trend started to turn around in the late 1990s as corporations found new uses for their existing mainframes and as the price of data networking collapsed in most parts of the world, encouraging trends toward more centralized computing.The growth of e-business also dramatically increased the number of back-end transactions processed by mainframe software as well as the size and throughput of databases.


    Availability.Mainframes have something called “five nines” availability which means that a mainframe’s “up time” factor is 0.99999 or put in plain English, a mainframe can run non-stop 24x7x365 supporting thousands of simultaneous users for a full year and can reliably be counted on to not be “down” for more than about 5 minutes total for the year.


    According to IBM, 80% of the world’s corporate data is still managed by mainframes.Long past their predicted extinction in 1996, mainframes are the only type of computing hardware that can handle the huge volumes of transactions used in many industries today, including banking, insurance, healthcare, government and retail.Mainframes are ideal for server consolidation, where one mainframe can run as many as 100,000 virtual Linux servers.More than a quarter of the mainframe processing capacity that IBM ships is used to run Linux.SUSE Linux Enterprise provides support for IBM z System mainframes.

    A glimpse into the future?

    I saw a very interesting demo machine a couple of years ago.An IBMer brought it to a demo of the Rational suite for a client.It was an Apple MacBook Pro with a full-blown instance of zOS installed.It was a single-user mainframe on a laptop.It was not, and still is not, a generally-available commercial product.

    History of Mainframe

  • In 1979, Digital Equipment Corporation (DEC) developed an operating system called the Virtual Memory System (VMS) for the new VAX mainframe (successor to the PDP-11 computer).
  • In 1984 estimated sales of desktop computers ($11.6 billion) exceeded mainframe computers ($11.4 billion) for the first time.
  • In 1991 Stewart Alsop, the editor of InfoWorld, predicted that the last mainframe would be retired by 1996.
  • In 1991, AT&T Corporation briefly owned NCR.
  • In 2000, Hitachi co-developed the zSeries z900 with IBM to share expenses, and latest Hitachi AP10000 models are made by IBM.
  • In 2002, Hitachi co-developed the
    zSeries z800 with IBM to share expenses, but subsequently the two
    companies have not collaborated on new Hitachi models.
  • In 2007,[34] an amalgamation of the different technologies and architectures for supercomputers and mainframes has led to a so-called gameframe.
  • In 2008, a new version of Mainframe was released, but renamed “Dataframe”.[5] A Comic Pack with Beach Head & Dataframe also has been released.
  • In 2012, NASA powered down its last mainframe, an IBM System z9.[20] However, IBM’s successor to the z9, the z10, led a New York Times reporter to state four years earlier that “mainframe technology—hardware, software and services—remains a large and lucrative business for I.B.M., and mainframes are still the back-office engines behind the world’s financial markets and much of global commerce”.[21] As of 2010[update], while mainframe technology represented less than 3% of IBM’s revenues, it “continue[d] to play an outsized role in Big Blue’s results”.[22]
  • In 2019, the product was branded Cloud Data Gateway for z/OS – reflecting its function as a mainframe backup and database image copy data mover to the cloud.
