IT Infrastructure - 2007Sicoob 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.

SUSE Linux Enterprise Server

Which Operating System was chosen ?

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: ‒ 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

IT Infrastructure – Timeline 2007-2012Sicoob IT Strategy

2007- SUSE Linux and System z begins- Acquisition of first mainframe z9

2008- Adopted mixed technology for z/Linux based on OS running on DASD and Data disk on FCP- Mainframe z9 replaced to z10

2009- More than 100 z/Linux guests- Geographical Contingency Project Starts

2010

- New mainframe z196 M49 with 16 IFL was acquired- More than 150 z/Linux guests

2012

- z/Linux guests upgraded to SUSE 11 sp2- Running 250 z/Linux guests

2011

- New mainframe z196 M80 with 38 IFL- Mainframe z196 M49 upgraded with more 20 IFL- Running 350 guests on z/Linux

19

IT Infrastructure – Timeline 2013Sicoob 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

SUSE Linux Enterprise Server for System zTechnical 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 business

● Hardware exploitation z196 processor topology and cache hierachy, increase cache hit ratio and therefore overall performance

● Increase of application workload density per system

● Increased performance

28

SUSE Linux Enterprise Server for System zTechnical 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 business● Hardware exploitation of the z196 instruction set for user land applications (ISV and self compliled applications), recompile programs with --march=z196 and/or –mtune=z196

● z196 optimized code and efficient excecution use less time and cycles for same workload

● Increase of application workload density per system

29

SUSE Linux Enterprise Server for System zTechnical 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

Thank you.
