Duration : 2 Days

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

• Describe the evolution of the data center, categorize the various server platforms, and servers that are commonly found there and their workloads
• Identify past, current, and future data center trends
• Describe the basic functions, characteristics, and terminology of z Systems servers
• Identify and list the various z Systems servers and hardware models, from zSeries server to the
• latest z14 and z14 ZR1 servers
• Identify the number of CPs and specialty processors available to various z Systems
• Identify and describe key components of z Systems and compare various z Systems
• components

                   - Frame layout, drawer, and cage usage
                   - Server models, processor drawers, books, memory, and cache structure
                   - Performance and millions of service units (MSUs) 

• Describe and compare I/O infrastructure and processor usage across z14 to zEC12 mainframes

                  - I/O drawers, cages, and technology used
                  - PU, cache, and fan-out connectivity

• Describe how and what z Systems physical components are used when processing instructions
• and performing an I/O operation
• Identify z Systems Capacity on Demand (CoD) options available for planned and unplanned
• outages
• Describe how logical partitioning is used, resource assignments, channel and CHPID types, assignments and initialization activities
• Describe the purpose and use of HCD
• Use the HMC to control basic operational tasks and monitor z Systems servers
• Identify and describe mainframe operating systems and their supported mainframe servers
• Describe the difference between a base and Parallel Sysplex
• Identify and describe the major enhancements provided by the recent z Systems software and
• hardware platform

The following are optional objectives in the z/Architecture and z/OS overview and concepts unit:

• Explain basic z/Architecture terminology and concepts for Real and virtual storage Address spaces, data spaces, and hiperspaces
• Identify processor architectural modes and their supported addressing implementations
• Define what is z/OS
• Name the server solutions included in z/OS
• Identify the characteristics of a base and Parallel Sysplex
• Identify current CFs and connectivity options
• Describe the purpose and use of the coupling facility
