Reports of the death of the mainframe were premature

Source: IBM Annual Report 2001

“I predict that the last mainframe will be unplugged on March 15, 1996.”– Stewart Alsop, March 1991“It’s clear that corporate customers still like to have centrally controlled, very predictable, reliable computing systems – exactly the kind of systems that IBM specializes in.”– Stewart Alsop, February 2002

Mainframes still dominate top enterprisesSome key mainframe facts

95 % of the Fortune 1000 enterprises use IMS– Originally written in 1968 to support NASA’s Apollo program25 of the world’s top 25 Banks, 23 of the top 25 US Retailers, and nine out of 10 of the world’s largest insurance companies run DB2 on System z490 of IBM’s top 500 customers run CICS– IBM’s CICS handles more than 30 billion transactions a day– IBM has 50,000 CICS customer licenses, and 16,000 customers– There are more than 950,000 CICS application programmersMore than 359 ISVs sell over 972 Linux applications on System z

Enabling growth through innovation that matters

Built upon Open and Industry standardsInfrastructure SimplificationIT Modernization and transformationIntegration and interoperationExtending management and control capabilities across your infrastructureDelivering ongoing improvements in availability, security, manageability, virtualization, scalability, multiple workload support, resource utilization, energy efficiency

IBM System z


The IBM mainframeDesigned to deliver the processing power business needs

A rich history of innovation and refinement– 40+ years of continuous innovation What do mainframes do these days?– Support multiple, diverse workloads

concurrently – Transaction processing / Batch / Web serving / ERP / CRM / Linux

Who uses mainframes?– Financial institutions– Municipal, state/provincial, and federal

governments– Retailers– Manufacturing

IBM System z


What makes a mainframe special?Legendary dependability

Can I count on a mainframe?– Less than 5 minutes downtime a yearHow do mainframes do this?– Hardware, software, storage, and network

designed for maximum application availability How can mainframes help you cope with planned and unplanned outages?– Unique mainframe clustering technology for

maximum up-time – Resilient recovery in multiple locations – Replicate data real-time at remote locations

and switch to replicated data without application outage

IBM System z


How do you manage a mainframe?Big function doesn’t mean big staff

Hardware / Software-based systems management that aligns system resources with business priorities– System responds automatically to assigned

policy – Management functions for centralized Linux

environmentsUse your mainframe as a hub to manage servers / subsystems in your IT infrastructure– Enterprise management software solutions

available from IBM and other vendorsAccurate and comprehensive charge-back informationMainframe skills– IBM Academic Initiative– Plentiful Linux and Java skills availableISV solutions available – Provisioning, management, and more

Cost of People vs. Spending on New Systems

How do you control management costs? Centralize workloads onto highly utilized mainframes

Do you recognize this description?– Thousands of lightly loaded servers– Hundreds of application instances– IT everywhere across the business

• Physically• Logically

– Thousands of distributed control points

The Result:– Massive complexity– Spiraling people costsCompounded by the inability to allocate IT costs to the business– Lack of internal costing

methodologies

IBM System z


How do you protect sensitive data?Mainframes deliver security

Protect the data– End-to-end protection that helps keep data

uncorrupted and uncompromisedPrevent unauthorized access– IBM and ISV access control solutions – Support for a variety of encryption

algorithms– EAL5 and other security certifications Secure and speed the transaction– Specialized Cryptographic co-processor

hardwareMonitor, manage, and control– Centralized access and control helps lower

security costs, meet compliance guidelines, and simplify audit trail.

Compliance with privacy/security legislation– Auditability – Control – RecoverabilityISV solutions available

IBM System z


Can you outgrow a mainframe?Here’s how to grow up and out, all with the same server

Adding capacity to a mainframe, or “scaling up”– Add new processors “on the fly” with

Capacity Upgrade on Demand• User initiated – does not require on-site

service• Add processing power economically for

specific workloads Adding more servers to a mainframe, or “scaling out”– IBM System z platforms can support up to

hundreds of virtual servers concurrentlyPay for capacity when you use it– On/Off Capacity on Demand lets you tailor

processor capacity to daily business needs

IBM System z


Can virtualization simplify my IT infrastructure?Mainframes – the leader in virtualization function

Share processor, memory, I/O, and network among multiple operating environments– Isolate workloads with EAL5 level security – Share resources among workloads– Enable communication for workloads internally

with an in-memory TCP/IP network 40 year history of virtualization, innovation and refinement– Hardware and software based for optimum

performanceand flexibility

– Robust suite of function for creating, provisioning, deploying, and managing virtual servers

z/VM Virtualization to simplify your IT infrastructure– Support up to hundreds of concurrent applications

with z/VM– Management tools for operation, maintenance, and

accounting
