Spring Connecticut CMG Conference and Vendor Day Meeting

April 21, 2017

This Spring Meeting brings back our popular Vendor Day format, to which we invite many software and hardware companies to exhibit their offerings.  Coffee and refreshments are served in the Vendor Hall, and a little more time is permitted between sessions for you to investigate their services.   Fees earned on Vendor Day help us to keep our admission prices low during the rest of the year, as well.

Held at the Courtyard by Marriott, Cromwell   4 Sebethe Drive, Cromwell, CT, 06416

z/OS GDPS Active/Active Overview  – Ellis Holman, IBM  

IBM’s Geographically Dispersed Parallel Sysplex – (GDPS®) active/active continuous availability solution is designed to provide near-continuous data and systems availability across sites separated by virtually unlimited distances. Join us for an overview of how GDPS active/active is structured. This session is intended to help you plan and implement a solution for your enterprise.

WLM Velocity Goals in the Year 2017 – Peter Enrico, Enterprise Performance Strategies 

Velocity goals have been around since the inception of the z/OS Workload Manager. Velocity is the goal that is assigned to longer running work when that work needs to make progress and there is no short response time objective. Unfortunately, achieving velocity goals are so heavily dependent on a variety of processor related factors such as capacity of the processor, number of processors, HiperDispatch, capping, defined capacity maximums, weight enforcement, specialty engines, SMT, and so much more.

During this session Peter Enrico will explain velocity goals and the latest influences in the modern day era.

Modern Performance Dysfunctions – Mark Tomlinson, Paypal

In this session I'll be sharing a review of recent experiences in performance engineering dysfunctions. Systemic mistakes, common blunders and lazy habits. These are shared in stories from testers who have changed their performance ways, started integrating performance into all aspects of their work. We'll cover new architectures, new tools, new problems, stupid human tricks and a review of a few classic stories from PerfBytes News of The Damned examples.  * * Editor’s note: This presentation earned the Mullen Award.

Cyber Security in Enterprise Networks  – John Corliss, Department of Homeland Security

In a world with cyber breaches occurring on a daily basis, a handful of actions may be taken to help minimize the cyber risk to any organization.  The five functions of the NIST cyber framework will be used to elaborate on key challenge factors present in the 21st century workspace.

Information Technology: The Next Fifty Years – Irwin Kraus, Hitachi Data Systems 

Software defined datacenter. Hyperconverged infrastructure. Containers. Big data. Cloud. Internet of Things.

These are some of the trends and technologies sweeping our industry. Where did we come from and how did we get here? This presentation will provide historical context and describe the how and why of these developments. We will explore the economic and technology drivers and attempt to separate reality from the marketing chaff.

Business Runs on IT – How Efficient is IT? – Jeff  Schultz, TeamQuest 

As capacity planning and management practices evolve, it is important for service owners and performance analysts to quickly identify unhealthy systems and systems at-risk of becoming unhealthy. However, it does no good to have perfect health and no risk if you’re throwing away money on underutilized systems.

In this session:

  • Learn how to ensure that your systems aren’t just healthy, but cost-efficient as well.
  • Always know what systems are over-utilized (warning – outage possible) and under-utilized (warning – waste happening) to fully optimize the delivery of your services.
  • Put IT services in a clear business context to enable IT leaders to spend less time putting out routine fires and more time creating additional value, giving their staff the flexibility they need to fully apply their expertise.
