10 Reasons to fall
in love with
The Mainframe
again…

Agenda
 Long Live the Mainframe
 CA Today
 Nice… but how do we tell others?
 New Technology
 How to make the most of it
 “Old things” don’t go away….
Long live the mainframe
 IBM’s MF revenue UP last 3 qtr
 IBM spends > $ 100 mln to make Mainframe easier to
use
 Enhancements include security, systems and data
management, and virtualization
 Since 2000 > 23,000 students from 300 colleges in North
America have been trained on MF
 PHP 5.1.2 now available for z/OS
 And much, much more…..
TCO…
 Illuminata Dec 2006
 Title: “IBM System z TCO: Man Bites Dog”
 Some highlights
 It does not make sense to measure TCO strictly on a “oneapplication-per-server” basis
 Measure with 10-50 applications on 1 Mainframe versus
10-20 blades or a grid of 50 distributed systems
 MF TCO is 30-60% better than 30 Sun servers or 300
Linux Servers
TCO… 2
 Some of the cost factors:
 Air conditioning and electricity
 People costs are a fraction of those required for distributed
systems
 Hardware costs have shrunk (from 65 to 20% of TCO)
 “Software license costs now competitive with other
platforms; especially zIIP, IFL and zAAP offer even lower
HW/SW pricing”
 “A new lease on life for the System/z”
The Mainframe Guru
Long live the Hype
 SOA will save us all
 SOX & other regulations
 Green is better…
 Security is hot (again…)
Something to think about…
 Sony’s Playstation 3 CELL microprocessor will be available
in IBM Mainframes. Companies will use mainframes to
run Virtual Worlds like Second Life
 Press: “Mainframes are big computers commonly used for
transaction processing and other centralized tasks”
 We can finally walk around in our own
mainframe in the future…
 But it’s more serious than that…
Maybe Spiderman
can protect us from
evil programmers
and we can speed up
DB2 by using Sonic
the Hedgehog??
Nice, but how do
we tell others?
Internal Marketing
This is all nice but….
 New applications are often NOT developed on Mainframe
 Mainframe people are not replaced when they retire
 We do more with less, and less and less
 So:
 We must promote our box AND ourselves
more and better
 We must emphasize the good things and make sure the
“bad” things are seen in context (expensive is not always
expensive…)
 We have to think like “them”….
New Technology
 The mainframe is getting more complex
 Java, Linux, Websphere, SOA etc…
 “Old” technology requires new thinking
 Open up legacy for SOA
 Networking now integrated across all platforms
 Databases have “relations” across networks
 Applications cross borders
 Complexity? What complexity?

The 10 reasons… I
 Security
 No external attacks, no malware
 Access Control & Audit part of eco-system
 Investment Protection
 20 year old apps run unmodified on latest hardware
 The co-exist with Linux & Java on same box
 Can me turned into SOA apps quite easy
The 10 reasons… II
 High Availability
 Do we need to explain???
 Workload & Performance
 90% of worlds largest databases
 Utilization close to 100%
 zIIP & zAAP for even better “spread”
 Efficient interoperability
 Co-host multiple systems and workloads
 Hypersockets between LPAR’s for sub second performance
The 10 reasons… III
 Lower overall Operating Costs
 Less systems, lower cost
 Energy
 Physical space
 Emergency Management
 Do I need to explain?
 Think about the “complexity…”
The 10 reasons… IV
 Scalability
 Anywhere from 26 MIPS for an entry-level machine to
17,800 MIPS for a 54-way multiprocessor system
 Parallel Sysplex can go to 500,000 MIPS
 Scalable Linux??
 Virtualization
 It’s part of the architecture, not an afterthought
 Centralized Management
 Hmm, ever tried that? It seems to work…..
Linux on Mainframe
 Slowly winning ground

30% year-on-year growth

390 Business Partners now delivering > 1000 applications on
Linux (100% growth)

20% of IBM revenue & 30% of MIPS now from Linux
 Red Hat & IBM agreed to join forces (May 10, 2007)
 “Greener” than blade’s
 Cost

Set-up & Operational costs lower

Initial costs higher
 Mainly for Development
Usage Trends
 Development Systems
 Integrated Build/Test/QA/Production
 Easy and quick to set-up
 Specialized Applications
 Security & Scalability are most important factors
 “Why Choose Linux on the Mainframe," by Brad Day
from Forrester
 “potential cost savings, productivity gains and improved
utilization rates through capabilities such as virtualization
and security and systems management"
Application Development
 Legacy Renewal
 Import existing Cobol & Natural
 Full documentation including In-depth analysis of code
 Migrate to Java & .Net
 Keep existing investments in Business Logic
CA and the

Long live CA… 
 CA trained > 60 people in Prague
 Announcement for zIIP support for 8 existing products
 New releases of over 16 products
 More in Beta as we speak
 New Mainframe Business Unit
 New Mainframe Affiliate Program
Valued Today. Essential Tomorrow.
 Our five year strategic commitment, we will:
 Build best in class mainframe solution support,
maintenance and optimization capabilities
 Drive a systematic means of customer engagement and
portfolio management
 Develop innovative and business compelling
mainframe software solutions
 Increase CA’s leadership position as the #1 independent
software provider in the mainframe software market
CA & the Future of the MF
 EITM
 Unify & Simplify
 Govern, Manage & Secure
 The Unified Service Model
 More integration, more ease of use
 A state-of-the-art SOA framework
 A World Wide Mainframe BU with very strong people in
the top
It’s time to fall in
love with the
Mainframe
Again….
