1 SICOOB The Second Largest Linux on IBM System z Implementation in the World Claudio Kitayama Thiago Sobral IT Infrastructure Analyst Sicoob claudio.kitayama@sicoob.com.br Sales Engineer tsobral@suse.com SUSE Brazil

2 Sicoob Credit Cooperative Bank - Foundation: 1996 (17 years) - Headquarters: Brasília, Brazil 2 - Number of Employees: 27,000 - Ranked in Points of Service: 6th

3 Credit Cooperativism It is an association of people who seek through mutual assistance, to make a better management of their financial resources What s the Purpose of Credit Cooperative? Providing banking and credit cooperation 3

4 Sicoob Sicoob is a financial institution that offers the same products and services as other banks. The difference is that Sicoob's costs are smaller. Private Pension Investments Payments Wire Transfer 4 Insurance Saving Account Consortium Debit and Credit Cards Loans

5 Regular Banks Headquarters Regional Branches Local Branches Clients 5

6 Sicoob Members (Owners): 2, Cooperatives: 529 Branches: 15 Confederation: 1 Bank: 1 6

7 Ranking Points of Service Ranking - Points of Service Raking Institution Points of Service 1º Banco do Brasil º Bradesco º Itaú Unibanco º Santander º Caixa Econômica Federal º Sicoob º HSBC Assets: US$ 17 billion 7

8 Sicoob's IT Evolution

9 IT infrastructure Timeline 2006 Before Consolidation and Virtualization One Datacenter (no redundancy) Entry Level Equipments Variety of Vendors and Models Equipment without warranty Software without support Heterogeneous architecture Low availability High Horizontal Growth 9

10 IT Infrastructure Timeline blade servers + 90 rack servers 300 servers Compaq Proliant IBM Blade Middle-range servers 8 servers 2 Itanium servers 2 serves IBM X3950 HP RX8620 IBM X335 IBM X335 / Waste of Resources Waste of Resources Waste of Resources - Total CPU 1056 cores - Total heat dissipation: BTUh - Average Consumption (CPU and Memory): 90% - Operational System Installed: Linux and Windows - Total power consumption:259 KWh - Number of Operational System: 310 servers Average infrastructure monthly cost: US$ 50,

11 IT Infrastructure Scenario Without Virtualization Today Difficulties Difficulties 1457 blade servers 71 middle-range servers Power consumption Data Center space Server maintenance Software licensing Low availability and scalability Points of failure Manageability Network assets/security Server Migration Average infrastructure monthly cost: US$ 234,

12 IT Infrastructure Sicoob IT Strategy In 2007 Sicoob stablished the strategy of Consolidation and Virtualization of Sicoob. It brought the dynamism flexibility and scalability necessary to be inserted on a high-tech scenario companies. The expected result was: - a fast technological infrastructure which follows up the business growth and expansion. - reduction of maintenance costs, licensing, management, power consumption, Datacenter s footprint and computational resources optimization. 12

13 IT Infrastructure Technological Guidelines IT GUIDELINES - Technological Initiatives: 14 Secure, available and updated solutions Focus on business growth Products and services monitoring Quality control Automation Licensing Savings

14 IT Infrastructure New Processing Platform Replacement Proposal Which Operating System was chosen? 210 blade servers + 90 servers rack servers 20 middle-range 300 physical servers Middle-range servers Fujitsu 8 serves IBM X335 SUSE Linux Enterprise Server 15 2 Itanium servers Mainframes 2 serves

15 What Is Linux on System z Linux on System z exploits the strengths and reliability features of the System z hardware, while preserving the openness of Linux Linux on System z is synonym for Linux running on any IBM mainframe: 16 IBM zenterprise EC12, IBM zenterprise BC12 IBM zenterprise 196, IBM zenterprise 114 IBM System z10, IBM System z9 IBM eserver zseries (z990, z890, z900, z800) S/390 (9672 G5, G6 and Multiprise 3000 processors) It is a native System z operating environment Pure Linux, an ASCII environment Exploits IBM System z hardware Not a replacement for other IBM System z operating systems Linux can be run under z/vm or in its own LPAR

16 IT Infrastructure Timeline Sicoob IT Strategy SUSE Linux and System z begins - Acquisition of first mainframe z9 - New mainframe z196 M49 with 16 IFL was acquired - More than 150 z/linux guests Adopted mixed technology for z/linux based on OS running on DASD and Data disk on FCP - Mainframe z9 replaced to z More than 100 z/linux guests - Geographical Contingency Project Starts z/linux guests upgraded to SUSE 11 sp2 - Running 250 z/linux guests New mainframe z196 M80 with 38 IFL - Mainframe z196 M49 upgraded with more 20 IFL - Running 350 guests on z/linux

17 IT Infrastructure Timeline 2013 Sicoob IT Strategy Mainframe z196 M80 expanded to 24 IFL more - Mainframe z196 M49 expanded to 11 IFL more - High-availability started with SSI and LGR on 2 Mainframes z196 - More than 450 z/linux guests Sicoob's Datacenter 19

18 IT Infrastructure Scenario Virtualizated 2013 Mainframes z/196 - M80 Processors: 60 IFLs Memory: 1136 GB Systems: - Banking core - Monitoring - Application Server - Data banks 20 z/196 - M49 Processors: 47 IFLs / 1 ICP Memory: 1136 GB Systems: - Business Intelligence - Baking Core - Monitoring - Application Server - Data banks z/10 - E26 Processors: 26 IFLs Memory: 768 GB Systems: - Baking Core - Application Server - Data banks

20 Sicoob's Case

21 IT Infrastructure Operating System Upgrade Case SUSE Linux Enterprise Server for System z 10 upgrade SUSE Linux Enterprise Server for System z 11 SP2 25% of performance gain Checking clearance SPB Financial Transactions 25% faster 24

22 SICOOB Business Issues Improve checking clearance Reduce transactions time Able to do more with same IT resources Powerful and reliable backoffice Reduce costs Business continuity Quality and security services 25

23 IT Infrastructure Operating System Upgrade Checking Clearance Case SUSE Linux SUSE Linux upgrade Enterprise Server for Enterprise Server for System z 10 System z 11 SP2 25% of performance gain Previous Environment 13 servers CPU usage: 100% Memory usage: 100% Processing: 1 million image checks per day Actual Environment 9 servers CPU usage: 50% Memory usage: 50% Processing: 2 million image checks per day Saving: US$ 1,013,

24 SUSE Linux Enterprise Server for System z Technical Features Enhanced CPU node affinity support for z196: This feature allows the Linux kernel scheduler to optimize its decisions based on the z196 processor, cache and book topology, and provides increased application workload density per system and much better performance technical 27 Hardware exploitation z196 processor topology and cache hierachy, increase cache hit ratio and therefore overall performance business Increase of application workload density per system Increased performance

25 SUSE Linux Enterprise Server for System z Technical Features z196 exploitation via alternate GCC: This feature provides performance improvement to applications through the exploitation of new z196 processor instructions and optimized code alignment. This increases the application workload density per system, less time and cycles are used for the same workload. technical Hardware exploitation of the z196 instruction set for user land applications (ISV and self compliled applications), recompile programs with --march=z196 and/or mtune=z business z196 optimized code and efficient excecution use less time and cycles for same workload Increase of application workload density per system

26 SUSE Linux Enterprise Server for System z Technical Features s390-tools: s390-tools enhancements: package with a set of user space utilities. It is the essential tool chain for Linux on System z and contains everything from the boot loader to dump-related tools for a system crash analysis Kernel 3.0.x: SUSE Linux Enterprise Server for System z 11 SP2 includes the Linux 3.0.x kernel derived from the upstream stable branch. This allows for enablement of the most recent hardware and provides massively improved I/O throughput and performance 29
