IBM Z: Technical Overview of HW and SW Mainframe Evolution (ES82G)

IBM Z: Technical Overview of HW and SW Mainframe Evolution (ES82G)

Overview

Duration  2 Days 

This course is designed to provide an understanding of today's complex system mainframe environment on the zEnterprise System and System z servers. It is mainly targeted for operators technical support, system programmers, and any others who need to keep current in this mainframe environment. Through lecture and hands-on exercises, you learn how the hardware and operating systems interact.

This course addresses the following topics:

  • Mainframes and distributed server comparisons: Why so many servers? 
  • Mainframe directions: Past, current, and future
  • Mainframes: System z introduction and relative performance comparisons
  • IBM System z hardware design: Frames, CEC cage, books, models, and MSUs
  • I/O infrastructure and processor usage: zEC12 to z10 comparisons
  • System z Capacity on Demand
  • Physical/Logical partitioning, server initialization, and CHPIDs
  • I/O configuration and HCD overview
  • MVS to z/OS software overview
  • z/OS Parallel Sysplex
  • z/OS enhancements on the zPlatform
  • z/Architecture overview and virtual addressing concepts
  • System concepts: The big picture
  • HMC introduction, groups, and activation profiles
  • Determining object status and error conditions
  • Activation and operating system interface
