Linux on zEnterprise, Easy, Scalable, High Available & Secure Hans Picht System z New Workload & Growth Initiatives Leader IBM Central & Eastern Europe [email protected]
§ Last year, 75% of the Linux code was developed by programmers working for corporations.
§ $7.37 billion: projected cost to produce the 283 million lines of code which are contained in Linux Distribution in a commercial environment.
§ IDC forecasts show that Linux server revenue will grow by 85.5% between 2008 and 2012 in the non-x86 server space equalling a four year compound annual growth rate of 16.7%.
§ Linux is Linux, but …features, properties and quality differ dependent on your platform
Hardware The industry’s fastest and most scalable and flexible enterprise server
The z196 offers a total of 96 cores running at an astonishing 5.2 GHz, and delivering up to 40 percent improvement in performance per core and up to 60 percent increase in total capacity for z/VM®, and Linux® on System z® workloads compared to its predecessor, the z10 EC. The z196 has up to 80 configurable cores for client use. The zEnterprise 196 allows Up to 3 TB of redundant array of independent memory (RAIM).
Designed and right-sized as an entry level mainframe server with increased flexibility, scalability and performance in a lower cost package
Powered by up to 14 total processors running at 3.8 GHz (10 of which are customer configurable). Supports up to 256 GB of real (usable) RAIM-protected memory—an industry exclusive currently available only on System z.
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.
• 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

Application Selection What applications are you going to run?
Have a look at the IBM Linux on System z ISV Application Directory: http://www-03.ibm.com/systems/z/solutions/isv/linuxproduct.html
• 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.

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
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.

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. Indeed, we are aiming to deploy our next nationwide application early next year, and hope to represent a leading example to other government agencies and businesses in Malaysia."
- Laila Binti Abdul Majid, Chief Assistant Director, JPN
Benefits: • Dramatically improved response times, increasing utilization of the
application to 100 percent and boosting employee productivity by an estimated 50 percent.
• Gained a highly reliable, stable platform making it possible to offer the SAL application 24/7 (previously it was available only during working hours).
• The Linux on IBM System z environment is highly secure and virus resistant, protecting the confidential data of Malaysia’s citizens.
• Moving to open source technology has introduced significant cost savings.

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.”
