    Tech Perspective: IBM’s S/390 server joi

    Locked

    by techperspective · about 23 years, 3 months ago

    The Linux operating system had its status boosted with IBM’s recent announcement that it’s making the S/390 server Linux-ready, but support by applications vendors is still lacking. Do you agree with Gartner’s position that Linux has a way to go before acceptance is widespread enough to be useful for the S/390 server? Would you consider the Linux operating system a viable alternative to Windows for running S/390 servers? What do you think are some of the advantages and disadvantages of this alternative? You can read the related Gartner article, which will be posted on 3:00 A.M. Monday, at http://www.techrepublic.com/article.jhtml?id=r00220000710ggp01.htm

      The S/390 is IBM big iron, which is to say it is a mainframe family. The IBM operating system called VM (I think) has the ability to run multiple virtual machines on one piece of hardware. By virtual machine I mean everything is virtualised so youcan run other operating systems such as OS/390 in multiple virtual machines on one box. (You can even run multiple VMs in VM and they can contain VMs too…

      Recently somebody ported Linux to the VM environment so you could run multiple copies of Linux on one box. They got it up to 40,000. So an ISP could buy a system 390 and rent out virtual Linux boxes to subscribers.

      “Would you consider the Linux operating system a viable alternative to Windows for running S/390 servers?”

      WHat kind of a dumb question is this? Windows doesn’t run on anything NEAR the size of an S/390 machine. When the choice comes, it is either between Linux or OS/390, and with Linux having the best momentum of any server platform right now chances are people are going to choose it. Gartner is a fine company I am sure, but they have been wrong before and their estimate of 2004 for Linux being able to scale seems a little long, considering it is used in hundreds of companies NOW for mission critical work.

      First and foremost, IBM’s motive for offering Linux on S/390 is to draw customers away from Microsoft. Anyone who has been a customer of IBM’s consulting services knows that they take every opportunity to turn customers away from anything and everything Microsoft: product, standard, etc. They denigrate Microsoft’s implementation of the Java Virtual Machine as “not open standard” while promoting WebSphere, which also requires an IBM-specific VM.

      Linux on S/390 will not impact their installed base of hardware users. It can only pull business from the high end NT/Win2K user group. As to long-term viability, we’ll all have to wait and see.

      Given that systems such as the 390 and the Sun E10000 run multiple virtual environments, I do not see Linux being on the 390 having a huge impact. I am more impressed with massively parallel Beowolf clusters. I think in reality, having a bunch of networked Pentium-class boxes running a cluster is more likely going to produce the desired results, unless, of course, the desired result is to “see if it can be done.”
