IBM Introduces Two Open-Source-Only Mainframes

IBM is introducing two mainframe servers that run only on the open-source Linux operating system.

The new hardware will make it easier to run technology like the MongoDB database and the open-source software Spark. Presently more than a third of IBM's mainframe clients are running the Linux operating system. IBM also said it will release mainframe code to the public and join a new cohort of less than a dozen academic, government and corporate entities in what's called the Open Mainframe Project, an open source endeavor devoted to helping companies using mainframe computers.

IBM is sweetening the pot by contributing 250,000 lines of mainframe code to the Linux community, hoping to attract a new generation of developers to their platform. To help coax new users, IBM will be offering free access to the LinuxOne cloud, a mainframe simulation tool it developed for creating, testing and piloting Linux mainframe applications.

Some of the specs for the machines can be found in this article from Reuters, including a partnership with Canonical Ltd. to distribute Ubuntu on the LinuxONE and zSeries systems.

    The new mainframe is explained (somewhat) here: http://techcrunch.com/2015/01/13/the-new-ibm-z13-is-not-your-fathers-mainframe/ [techcrunch.com] and more detailed specs here: http://www-03.ibm.com/systems/z/hardware/z13_features.html [ibm.com]

    Its not what you think it is. It is a massively parallel processor platform with a chipset of their own design, and huge numbers of cores per processor (up to 141 cores per processor, but each machine can have many processors of different types).

    And its pretty small compared to the mainframes of yesteryear. Its heavy in Cryptographic processing at every step in the transaction process, on each core in the machine.

    It is designed for a different work load than Google's concept of massively parallel cheap computers.

    Contrary to the summary, these things are not Linux only. There are a bunch of different OS's that it can run, including Windows Server 2008 and 2012, and AIX.

    Good stuff from frojack. Continue to mod him up.

    these things are not Linux-only

    It appears that patella.whack is trying to steal away my Linux Fanboy crown.

    a chipset of their own design

    ...but I see nothing that says the processors have an architecture that is not x86-compatible.
    ...though, if they were to stop funneling bucks to an outside silicon vendor|"intellectual property" gatekeeper, that could do good things for IBM's bottom line.

    I had heard rumors that Visduh10 would drop support for ARM(v7).
    While M$ appears to be distancing itself from its ARM-using Surface line, "10" still appears to support ARM.
    So, even if IBM had gone with ARM architecture for this, Windoze wouldn't be aced-out.
    Supported architectures, Windows NT [wikipedia.org]

    ...and for comparison: Supported architectures, GCC [gnu.org]
    The line above 3.18 in the ToC is the nugget.

    There are a bunch of different OS's that it can run

    z13 Features (your 2nd link)[1] [ibm.com]

    Through its hybrid computing capability, IBM z Systems with IBM z BladeCenter® Extension (zBX) also supports IBM® AIX® on Power, Microsoft Windows® and Linux® on System x®

    Now, IBM -has- been playing down the Windoze angle for quite some time.
