Seminar Abstract and Outline
Seminar Overview:
Do you have the responsibility of capacity planning of your zArchitecture systems? Are you just beginning to put together a capacity plan and want to learn the latest capacity planning techniques? Or do you have a capacity planning project in progress would like to verify your results with a renowned capacity planning expert? Or maybe you've already done you capacity plan and the upgrade is complete, but now you want to understand how you could have done it differently to help you prepare for next time.
In this seminar you will learn capacity planning techniques from someone who many in the mainframe computer industry deem as the number one expert: Ray Wicks.
The seminar discusses performance analysis and capacity planning techniques with emphasis on large processor systems (zArchitecture platform). In fact, examples will be largely drawn from the z/OS Operating System.
Although emphasis is placed on large processor systems and examples will be largely drawn from z/OS the concepts apply to all levels of operating systems and hardware. The lectures on performance analysis and capacity planning include topics such as architecture, queuing theory, sample selection, trending and more. The student exercises are built using EXCEL. Using EXCEL in hands-on labs you will execute some of the examples in the lecture. Data will be provided for the hands-on components.

This seminar is for you…
- if capacity planning is a keen area of interest for you and you want to hone your skills by learning from a man many consider the leading capacity planning expert for the z/OS platform
- if you want to learn how to put together a capacity planning
- if you are planning for an upgrade and want to learn effective sizing approaches
- if you are considering a server consolidation and want to ensure that the effects on capacity are understood
- if you already performed an upgrade or server consolidation and you want to validate your capacity planning approach
- if the purse strings are tight and you need to ensure the upgrade you will recommend is going to be sufficient

Audience:
This 3.5 day seminar is designed for capacity planners and performance analysts who are responsible for putting together computer capacity plan for their z/OS systems and sysplexes. Whether you are preparing for a machine upgrade or just a reconfiguration or server consolidation, students will leave the seminar knowing the key techniques and approaches for putting together such a capacity plan.

Prerequisites:
It is expected that the attendee will have a laptop with EXCEL already installed. Data files and EXCEL Worksheets to execute class exercises (using the student's own installation data) will be provided during the seminar.
A basic understanding of z/OS (or OS/390) and RMF are assumed.

Seminar Objectives:
This seminar is designed to provide the attendee with a fresh outlook on the performance management of their z/OS systems, sysplexes, and DASD I/O subsystems. It is designed to guide you in learning the basic concepts of z/OS performance management by teaching you a step-by-step approach to z/OS performance evaluation. You will learn how to analyze z/OS and OS/390 performance measurements. You will learn performance management of your own DASD I/O subsystem, processors and LPARs, MVS storage and Workload Manager service definition.
At the end of the seminar students:
- should understand the basic principles involved in Performance Analysis and Capacity Planning
- should be able to both identify and analyze the data required for an analysis
- should be able to produce a quality deliverable detailing the analysis

Seminar Participation:
Prior to the seminar, enrolled students will be sent a note suggesting what configuration data and measurement reports should be collected and brought to class. The purpose of this information is two fold. First, it ensures that each attendee is familiar with their current or planned environment. Second, data brought to class could be used to reinforce concepts learned by using the data during class exercises. Ray is available before class, during breaks, and after class to discuss with each student their own environment.

Seminar Outline:
The following is a high level outline for this seminar. A detailed seminar outline is available upon request. Please feel free to contact Ray Wicks directly for more details or to find out if this seminar is right for you.
Performance Analysis
This part discusses the performance factors that determine the responsiveness of a Host system. (z/OS is used as an example in most cases.) Topics include performance factors of the following resources. Indicated is a selection of the topics by resource.
- Queuing Theory Review versus Simulation
- Processor
- More CPs or faster CPs?
- Hardware and software factors
- Performance and capacity thresholds
- Processor performance data
- Single system image versus multiple images (LPAR)
- Performance factors for z/OS Parallel Sysplex
- Processor Storage
- The storage hierarchy
- Storage performance data
- I/O subsystem
- I/O events tutorial
- DASD and cache controllers
- I/O performance data
- Using rules of thumb for a Health Check®
Capacity Planning
The concepts covered here are necessary for anybody engaged in capacity planning and using any capacity model. Concepts taught and enforced in the seminar include:
- I/O-CPU implications of the forced flow law
- Relative I/O Content (RIOC)
- Saturation Design Point
- Resource Metrics
- Sample Selection
- Relative Processor Power (ITRRs, and MIPS)
- Capture Ratios
- Processor storage estimation
- Parallel Sysplex considerations
- Capacity comparisons for Production Systems
