IBM Announces First Linux-only Mainframes

A reader writes "The new Z-series mainframe for Linux, which costs $400,000 and is aimed at processing transactions at large businesses, is IBM's first mainframe computer sold without IBM's traditional z/OS mainframe operating system. More info at the IBM zSeries page" This is something that IBM and others of Big Iron vendors of *NIX have said - as Linux grows in maturity, they want to replace their *NIX with Linux. However, there's still work to be done in that area.

  1. HOT SWAPPING!!! by Maddog_Delphi97 · · Score: 3, Interesting

    Does it support Hot Swapping?

    I would think hot swapping would be one feature truely worthy of a mainframe operating system... especially if you can all of the different possible parts of a mainframe and still keep all of your applications running 24/7.

  2. Licensing discount? by grub · · Score: 4, Interesting


    (nb: The last IBM big-box I worked on was a first generation AS400 so this question may be dated)
    I recall licensing of IBM's OSs to be fairly expensive, have they cut prices at all to reflect the fact that a lot (the bulk?) of the vanilla Linux development happens outside IBM, therefore costing them nothing?

      Acording to the article the answer seems to be yes. They said the $400,000 linux box was about equal in power to a $750,000 mainfraim. So around $350,000 in OS savings.

    Will this mean that IBM will finally replace OS/2 as the bootstrap and control server?
    Replacing that with Linux would be a nice start!

    For those that do not have the benifit of a 390 sitting behind them, it is very disconcerting to have that big black IBM monitor on top of it, because it is running OS/2 on a Celeron board inside the mainframe to control the whole show.

      Give me a break. Someone seems to mention this almost every time an article discussing IBM mainframes comes up. If you (gasp!) UNPLUG that OS/2-running laptop, watch what happens. Will your network collapse? Will the entire thing end in a bunch of flames?

      You'd be quite bored to notice that things keep running just like normal.

      The only purpose of the controller computer is to configure the mainframe, provide quick access to load information, etc. The mainframe is entirely self-reliant, and does not need the controller for normal operation. (It does communicate with the controller frequently during normal use, but none of that communication is mission-critical.) The sole time that the laptop is required in order for the mainframe to be even operational is to load the bootstrap, and for that purpose I could care less if the thing ran DOS.

    Architecture is the key. What's the difference between a 120 MIPS mainframe and 3000 MIPS desktop, and why is the 120 MIPS mainframe faster in mainframe type applications?

    Exactly. The point that most /.ers seem to forget is that not every computing task is cpu bound. Mainframes are a specialized tool for doing a specialized job, namely processing a huge number of transactions quickly, in a totally reliable manner. CPU speed is not the limiting factor for this type of task -- I/O throughput is; and this is precicely where mainframe architecture beats the pants off of x86 hardware. If you don't understand the strengths and weaknesses of the different kinds of computer architectures, you don't have any business making technical reccomendations to your employer.


    A good engineer picks the best tool for the task at hand. Depending on the computing task, the best computer could be a mainframe, a MPP supercomputer, a commodity SMP server, a cluster of desktop PCs, or some other specialized architecture.


    Commidity x86 hardware is great, and can do an acceptably good job on a wide variety of tasks, but it isn't the be-all and end-all of computers. Just because you haven't worked on anything else doesn't mean that other computer architectures are outdated crap.

    Without Linux, how long would it take for Microsoft to take the whole server market away from Sun? The trend was set when they released two different versions of NT, "workstation" and "server". The fact that they don't have any version called "server" anymore may reflect a reality check they have done, realizing it will not be so easy after all.

  6. Datacenter in a box by ehiris · · Score: 4, Interesting

    My company purchased one for web hosting

    The system uses VM as a base but has multiple instances of SuSE running. It is able to run up to 10000 instances of Linux which makes it a data center in a box.

    There is no bus and the communication between the processor banks, memory, ... are switched.

    First time I've seen it my eyes jumped out of the sockets.

    Good Job IBM :)
