A little look at the past



The NASDAQ (or Dot Com) Bubble of the late 1990s http://www.housingmarketnews.net/asset-bubbles/dot-com-bubble.php

1998 – 2000: The Dot Com Bubble



1998 – 2000: Microsoft Windows 2000



The number of people running Linux is estimated at over 10 million, making it not only an important operating system in the Unix world, but an increasingly important one in the PC world.

1998 – 2000: Linux Kernel 2.2 Released



1998 – 2000: The Melissa Worm Attacks the Internet



The IBM e-business campaign established IBM's unique role in the Internet arena by introducing a new buzzword: "e-business."

This term defined IBM's vision for doing business in the Internet age and provided IBM with an instant association with the web.

In the beginning … Bigfoot

•  The original i370 project was started in August 1998 by Linas Vepstas, at the instigation of Daniel Lepore

•  Later, Neale Ferguson, Peter Schulte-Stracke, and Rob van der Heij joined in to provide code and shoot bugs

•  Rick Troth helped with boot-loader issues

•  The result of this effort was a compiler, an assembler, a port of glibc, and a kernel that would usually boot but was missing important features, such as disk drivers and network drivers, never mind a variety of infrastructure

Platform Selection



How Do Companies Typically Select a Platform for Their Applications?

They’re done! But this is just a TCA view… Is that all they should be thinking about?

Their first question is:

–  “Will it run there?”

Their second question is:

–  “How much does the hardware cost?”



•  Shouldn’t they have asked questions about: –  Scalability? Availability? Backup? Site disaster

recovery? –  Security? Reliability? Data integrity? Maintainability? –  Volumes and service levels? –  Floor space? Power? Cooling? –  Operations? Scheduling? Monitoring? Server

management? –  Integration? Performance and value of data proximity?

Questions that lead to a more complete TCO view must be considered…

•  Not everything that runs on Linux is available for Linux on System z. (Open Source included!)

•  Ask your ISVs to be specific; they may need to “get back to you.” •  All Open Source, all commercial, or a mixture? •  What are the virtual/real storage requirements for the applications to

be run? •  Oracle can be a tremendous storage hog: But the per-processor

licensing can give big savings on the software license •  How much disk space is going to be needed? •  This can drive the decision on SCSI versus ECKD •  Aggregating 3390-#'s into multiple Terabyte file systems is a pain

Business need: EFiS EDI Finance Service AG had been using a collection of x86-based servers running Linux software to support its mission-critical applications and processes. However, the servers were not meeting the company’s performance or scalability requirements. Solution: PROFI Engineering Systems AG helped the company migrate its mission-critical applications from x86-based servers onto a single IBM Enterprise Linux Server (ELS) – an IBM System z9 Business Class platform running Novell SUSE Linux Enterprise Server for System z. The company then saw an opportunity to expand its IBM and Linux investments and improve the company’s overall services by updating its data center and installing a new ELS, based on IBM System z10 Business Class hardware.

The consolidated IBM System z9 BC and IBM System z10 BC servers successfully streamlined the data center to optimize maintenance and management processes and effectively reduce costs. The virtualized IBM System z environment offers much higher than average processor utilization levels, so a single IFL processor is able to handle workloads equivalent to a large number of x86 servers. This is particularly significant for software which is licensed on a per-processor basis, as is the case for many of the company’s business-critical applications. As a result, the company was able to enjoy instant savings by migrating these applications to the SUSE Linux Enterprise Server solution.

Benefits: §  Successfully consolidated IT environment while deploying hundreds of Linux

instances to support its performance requirements. §  By retiring unnecessary and underperforming hardware, the company was able to

double processing speeds and optimize its data center. §  The implementation of the SUSE Linux Enterprise Server software and System z

technology enabled the company to optimize its fully realized disaster recovery plan.

“The z10 IFL engines in the new ELS not only run Linux environments approximately twice as fast as the previous generation – they also offer around 40 percent more capacity, enabling us to expand our Linux footprint without increasing our costs.”

— Colin Clews, Technologies Manager, Atos Origin

Business challenge: To introduce new applications for major clients in the insurance and rail transport industries, Atos Origin needed be able to support large numbers of users and high transaction volumes. The company required a high-performance infrastructure that could offer 24x7 availability.

Solution:

Atos Origin decided to implement the new applications in Linux environments running under z/VM on an IBM Enterprise Linux Server (ELS). The ELS is an IBM System z10 Business Class server which uses Integrated Facility for Linux (IFL) engines to deliver excellent price-performance.

Benefits:

§  The z10 IFLs in the ELS deliver up to 40 percent more capacity at half the price of the previous generation – a price-performance improvement of up to 65 percent.

§  Running multiple Linux environments on a single ELS can potentially reduce TCO by up to 80 percent, compared to a traditional distributed x86 environment.

§  IBM Capacity Backup Upgrade enables full, rapid disaster recovery while keeping operational costs low.

“The IBM ELS has the potential to provide the best of both worlds for our clients – combining the traditional reliability, availability and serviceability of System z with the openness and flexibility of Linux.”

— Paul Casey, Datacentre Platforms Practice Leader,

Computacenter

Business challenge: With many of its clients keen to move their business-critical systems onto Linux, Computacenter wanted to find a way to deliver world-class availability and security for Linux environments at a competitive price-point. Solution: IBM helped Computacenter deploy an IBM Enterprise Linux Server (ELS) at its Hatfield Solution Centre, enabling the company to run proofs-of-concept demonstrating the superiority of Linux on the mainframe over traditional distributed server architectures.

Benefits: §  The ELS can host thousands of virtual Linux environments within a

single physical footprint – improving energy efficiency by up to 90 percent and supporting Green IT objectives.

§  Powerful IBM Integrated Facility for Linux (IFL) processors reduce the cost of per-processor licensed software (such as Oracle) by up to 97 percent.

§  IBM z/VM enables new Linux environments to be provisioned in minutes with no need to procure new hardware, increasing enterprise agility.

Computacenter helps clients cut costs with the Enterprise Linux Server offering from IBM - Efficient, rapid and flexible


IBM zEnterprise - Freedom by Design Eurocontrol consolidates IT environment into virtual hybrid datacenter Business challenge: Due to the growing number and diversity of applications in the past decades, the need for more server capacity has evolved. This has over time resulted in a rapidly growing datacenter, at the expense of the manageability and efficiency of IT systems.

Solution: To achieve … a smart datacenter, Eurocontrol and IBM are consolidating part of the present server environment into a virtual hybrid datacenter based on an IBM System zEnterprise Server with Linux as operating system. This environment is extremely well suited to operate Linux on System z, as well as to operate Linux on Intel blades and Power blades.

Benefits: §  The new heterogeneous virtual IT infrastructure will give Eurocontrol MUAC greater flexibility and

scalability. §  The centralized supervision substantially improves the user friendliness and management of the

environment, meeting the IaaS service levels. §  Applications run faster and are available 24/7 thanks to the immense computing power and capacity of

the hybrid environment in combination with the fit-for-purpose principle. §  Less hardware -> more floor space in the datacenter, major energy savings -> reduction in CO2

emissions, easier system management results in an even greater financial benefit

“For some software products you need to pay a separate license for each server core. Since the zEnterprise uses the Integrated Facility for Linux instead of cores when calculating license costs, we can reduce the number of these licenses and thus save license costs.”

— Huub Meertens, Head of the SUP Engineering Section at

Eurocontrol MUAC

Business challenge: Here was the challenge presented to John Palmer by his director, Winston Sorfleet: “I want you to find new ways to use and grow the [new mainframe] technology.” In a large organization with a variety of platfoms, competing IT agendas, and a history of diffuse control, this is easier said than done. Solution: The Canada Department of National Defence (DND) path to enterprise hosting with the z196 began with consolidation within the mainframe group itself. Palmer brought all three existing mainframes under centralized organizational management. This entailed the consolidation of all mainframe-related tasks, including: • Hardware / Software / Storage support • Contracting for Software / Hardware / Maintenance • Business Recovery contract management • Role of BR Manager transferred as well • Transfer of all mainframe-related funding At DND Palmer certainly encountered resistance. He overcame the resistance by setting up a proof of concept (POC) around Oracle running with Linux on System z. Based on the results of the POC, Palmer could build a compelling business case emphasizing the dramatic licensing cost savings. With the strong support of management, the mainframe group prevailed.

Source: Independent Assessment case study 2011: public.dhe.ibm.com/common/ssi/ecm/en/zsl03125usen/ZSL03125USEN.PDF

Benefits: •  You continue to manage/administer your applications as before—the mainframe is only managing the virtualized hosting

platform they are running on. •  Your AIX®, Linux, Power™, and x-based skills continue to be valuable—those operating systems and platforms remain

viable and active in the enterprise as do the applications running on them. Thus, your skills continue to be in demand. •  You get rid of platform headaches—the System z team will manage the platforms while you get to do the rewarding work

with the applications and users without platform worries.

Business need: The National Registration Department of Malaysia found its existing infrastructure lacked the power to reliably support it. Access issues, slow response times and crashes led to high numbers of user complaints, leading to some employees refusing to use the system. This prevented critical information being distributed, uploaded and downloaded. Solution: Implemented an IBM System z10 Business Class™ server running the IBM z/OS operating system; activated an IBM Integrated Facility for Linux engine to handle Linux workload cost-effectively.

"We are very proud to be known as the first in Malaysia to embrace Linux on System z, and the success of this project has led to extensive plans to develop this environment further in the future.

National Registration Department of Malaysia ... Supporting super-reliable access to business-critical applications with Linux on IBM System z



Sparda Datenverarbeitung eG

SDV runs a number of very large databases within the virtualized Linux environments … The company also relies on SUSE Linux Enterprise Server to support online banking services for the Sparda Banking Group's 4.2 million customers.

Working with IBM, SDV deployed an IBM z196 at each of its two data centers, activating six Integrated Facility for Linux (IFL) engines on each box.

“Our online banking services process approximately 1,200 online transactions per second, so we simply cannot afford them to fail. SUSE Linux Enterprise Server, which is involved in a significant part of this workload, makes us confident that this will not happen. Since deploying SUSE Linux Enterprise Server on the IBM z196 we have experienced over 99 percent availability. This proves that Linux's reputation for stability and reliability is well and truly deserved. We imagine the solution will play an integral role in SDV's infrastructure for some time to come.”

- Bernd Bohne, Department Head, Central Systems Technology, Sparda-Datenverarbeitung eG

Notes: Performance is in Internal Throughput Rate (ITR) ratio based on measurements and projections using standard IBM benchmarks in a controlled environment. The actual throughput that any user will experience will vary depending upon considerations such as the amount of multiprogramming in the user's job stream, the I/O configuration, the storage configuration, and the workload processed. Therefore, no assurance can be given that an individual user will achieve throughput improvements equivalent to the performance ratios stated here.

All customer examples cited or described in this presentation are presented as illustrations of the manner in which some customers have used IBM products and the results they may have achieved. Actual environmental costs and performance characteristics will vary depending on individual customer configurations and conditions. This publication was produced in the United States.
