A simple question to profis

  • 1.  A simple question to profis

    Posted Tue April 25, 2023 04:46 PM

    Hi everyone, 

    As a novice in IBM Z tech and learning path, am wondering  to know in simple human words, what is the difference between today's IBM Z from all previous ones and existing ones from other high tech companies.

    I appreciate your answers.

    Kind regards,
    Kanatbek Abdurasulov

    Hi Kanatbek,

    if you are asking for todays IBM Z, I think you refer to z16. While there are many improvements compared to previous generations, the main differentiator is the Tellum Chip with an integrated AI unit.

    The main difference for me between IBM Z and other architectures is that it's build for data processing rather that computation. That means, while you have 200+ cores in one machine, it can drive massively more I/O. Most business workload is build that way. Think about an money transfer from one account to another account. That very few computation but many I/Os. That way, you can run your cores constantly at high utilization.

    Is that simple enough?

    Regards,

    Michael Groetzner

    Hi Kanatbek,
    There would be lots to tell about the IBM mainframe history HW constant evolution and its architecture. You may want to start at the current IBM z16 machine and discover all of its features as Michael suggested.

    This general site seems interesting to discover IBM Z =>  https://www.ibm.com/topics/mainframe

    Also, as there are many resources available for education, please see for example:

    Welcome to this wonderful platform for which you shall find many many courses and badges to help you learn about it !

    Kind regards.

    Hi Kanatbek,
    I fully concur (liked) the previous responses.  My view of the IBM mainframe past, present, and future, 1) IBM mainframe was built from the ground up for business (data I/O throughput, I/O device independence, upward compatibility, reliability, availability, serviceability, scalability, security which is uncompromising design criteria for the past 60+ years and subject to relentless technological advancements) 2) The holy grail of business is deep advanced analytics at the time of transaction.  The latest IBM Z mainframe, z16, is a significantly new technology step enabling the 'holy grail of business'.

    Hi Kanatbek, I found a ton of interesting info about IBM Z and it's competitors on Wikipedia (Surprisingly!).  The best thing I read said the market consists of "IBM and the 7 Dwarfs" meaning the IBM is the biggest, most recognized, and best brand.  For IBM Z, the Z stands for zero downtime. Each version improves upon the last, so all companies should strive to stay on the latest and greatest version.  Do you have any follow up questions for us?

    Hi Kari,

    Thanks for your reply. 

    In your explanation on the IBM Z the word 7 dwarfs caught my eye, and I'm wondering who the 7 dwarfs might be when the IBM is the biggest. Do you mean by 7 dwarfs the corporations such as Apple, Microsoft, Google etc. ? :)

    Kind regards,
    Kanatbek

    "IBM and the Seven Dwarfs" was a 1960s reference to the companies manufacturing business computers:

    Burroughs,
    UNIVAC,
    NCR,
    Control Data Corporation (CDC),
    Honeywell,
    RCA,
    General Electric.

    The first five were also collectively called "BUNCH".

    Hi Scott,

    Thanks for your answer.  I looked  into all corporations on the internet and all are focused on electronics and supercomputers during the period of 1960s - 1970s.  According to Wikipedia there were  probably 9 (dwarfs) : CDC, IBM, Burroughs Corporation, DEC, NCR, General Electric, Honeywell, RCA, and UNIVAC. 

    An Insightful information for a person from the high mountains lying in between heavens :)

    Kind regards,
    Kanatbek

    RCA manufactured the Spectra 70 series which was directly compatible with the IBM System 360. RCA competed heavily against IBM, until the exited the business.

     

    All of the others had their own proprietary architectures.

     

    CDC was more in the scientific market than the business/commercial market. (Before the System 360, computers were either "scientific computers" or "business computers: -- basically, floating point or decimal arithmetic. One of the significances of "360" in the name was that the line addressed the whole compass of needs: scientific to business.)

    Apple, Microsoft and Google did not exist! Hard to believe, but true!

     

    But you have the right idea.
