common challenges
Common Challenges
  • System z is too expensive
  • System z is legacy, stabilized and new development should be on other platforms
    • Then, the z will eventually go away
  • I’m afraid if I use z I will have a “single point of failure”
  • The MF skills are all ready to retire—who will support “anything” MF going forward?
  • In what decade was the first MF?
    • What was its name?
  • Last year, the world produced more transistors than grains of rice? t/f
  • What MF name was used for the first follow on MF from above?
  • By 2010, there will be more than 30 billion RFID tabs in circulation. t/f
  • What version of MF would used in the 90’s?
  • What is the major database used on MFs?
  • There are more than 1 billion camera phones in use today? t/f
  • What has been the most prevalent programming language on the MF?
  • What are “modern” languages being used on the MF?


why take this course
Why take this course?
  • Jobs
    • Know companies like Baldor, Data-Tronics, Dillards, JB Hunt, Walmart, etc.
  • Additional computing platform that many students do not have opportunity to learn
  • Broading skillsets as System z becomes more open and accessible
  • Fast growing server—appears to continue as a major computing platform
  • RAS—Reliability, Accessibility, Scalability
  • Did I say Jobs? Or did I say Jobs?

Platform choice – Fit for purpose, workload and situationMany factors influence a platform selection, making it difficult to present a simple selection matrix.

A government organization consolidates applications and data to drive down costs of hardware, software and management by 70%!
