Agenda • History and current status of the zSeries SIG group • What is Linux on System z? • Customer Trends running Oracle on Linux on System z • Top ten reasons to run Oracle on Linux on System z • Real life experience migrating to Oracle/Linux on System z • Reference material • Questions
History of zSeries SIG Group • User Group formed over 23 years ago • One of the oldest Oracle SIG’s • Started with Oracle on MVS • Moved 8 years ago to include Oracle on Linux on System z • z/OS Oracle de-support • Small technical community and growing
Current status of zSeries SIG Group • 2008 and 2009 yearly conference attendees were mostly Linux • Oracle on Linux is more streamlined than Oracle on z/OS • In 2010 joined IOUG as a SIG • zSeries SIG sessions held as part of Collaborate • IOUG has been very helpful
Future of zSeries Oracle SIG Group • Join our Round Table Session on Monday 02:30 PM • Session 261, Room REEF B • zSeries Oracle SIG Panel Discussion • Panel • Oracle • IBM • zSeries Oracle SIG Committee
What is Linux on System z? • It is not your parents mainframe anymore!
What is Linux on System z? • A native System z operating environment • Pure Linux, an ASCII environment • Exploits IBM System z hardware, including IEEE floating point • Linux for System z – 32 (31) -bit/64-bit • Not a unique version of Linux or other operating system • Developed and supported by the Open Source Community • Distributed by Novell SuSE, RedHat, and Others • Not a replacement for other IBM System z operating systems (z/OS formally MVS/OS/390) • Can be run Virtual under z/VM or in its own LPAR • Hardware provides a pool of virtual capacity • Only fully supported Oracle environment in a VM aside from Oracle’s VM
Virtual Machine Partitioning Example for Linux on System z TEST LPAR PROD LPAR Oracle DB TEST 1 Oracle DB TEST 2 Linux Hundreds to Thousands of guests=> Web or App Server Web or App Server Oracle DB PROD 1 Oracle DB PROD 2 Linux Lin Linux Linux Linux Linux z/VM PR/SM I/O and Network Memory Processors Easy to create new images, easy to manage
What System z Hardware Brings to Linux: • The most reliable hardware platform available • MTF measured in decades • RAS features built into hardware • Scalability • Both Physical and Logical • Non-disruptive capacity upgrade on demand • Designed to support mixed work loads • Complete workload isolation • High speed inter-server connectivity • High Internal Bandwidth, sophisticated cache nest • Virtualization
What System z Hardware Brings to Linux (cont’d): • Hipersockets • Virtual network between LPARs, at memory speed • Network stays inside the box - secure • Integrated Facility for Linux (IFL) CPU • Full Processing Speed, not clocked down • IFLs upgrade as hardware is upgraded: z9>z10: 50% performance increase • Processor-based software costs
Customer Trends • From a perspective of the z Series SIG group • Trend is to move to Linux • Oracle strategic direction is Linux • Oracle and IBM are supporting Oracle products on Linux on z • Long list of 3’rd party vendor now support Linux on System z • Steady yearly growth usage of Oracle on Linux on z • Steady growth of Oracle solutions available on Linux on z
Top ten reasons for running Oracle on IBM System z • The Mainframe has been the platform for mission critical • applications for years • Reasons may vary why companies choose to run on the mainframe • Objective of this session is to list some common reasons • You can see if these fit your situation
Top ten reasons for running Oracle on IBM System z • Excellent virtualization capabilities of IBM System z, highest resources use efficiency/utilization, mixed workloads • Ability to exploit existing disaster recovery plans • Lowest security breach risks/costs via most secure design, encryption, etc • High availability features provided by IBM System z • Lowest power consumption, cooling, and data center floor space • Ease of interfacing with traditional data • Increased performance and scalability capabilities of z10 • Specialty engines available on IBM System z • End to end solution for dynamic infrastructure data center • Lowest total cost of ownership, total cost per user, and total cost per transaction
Details on using the VM Operating System The solid virtualization capabilities of z/VM and System z are a key reason Mature technology VM/370, introduced in 1972, enhanced and significantly expanded for Linux in recent years. For ORACLE SOFTWARE - Only fully supported Oracle environment in a VM aside from Oracle’s VM
Details on Reason - VM (cont’d) Software Hypervisor integrated in hardware Sharing of CPU, memory, and I/O resources Virtual network – virtual switches and routers Virtual I/O (mini-disks, virtual cache, and so on) Virtual appliances (SNA/NCP, and so on)
Details on Reason - VM (cont’d) Easy management Fast provisioning of preinstalled and configured Linux images. This can be accomplished in minutes instead of days or weeks. No additional space, electric connections, or network cables.
Details – Consolidation Benefits Consolidate workloads – Green Feature Use less power (electric) Distributed servers often run at average utilization levels in the range of 5% to 20%. Run multiple images on fewer processors Achieve utilization levels of 85 or 90 % or more
Details on Reason - Security • Integrated cryptographic accelerator • Advanced Encryption Standard (AES) 192 and 256 • Stronger hash algorithm with Secure Hash Algorithm (SHA-512) • Tamper-resistant Crypto Express2 feature • Supports high levels of security for demanding applications • Fully programmable and configurable • Highly scalable performance for SSL transactions • Trusted Key Entry (TKE) 5.2 with optional Smart Card reader
Details on Reason - Security • IBM LPARs have been certified to the security level of Evaluation Assurance Level 5 (EAL5) • z/VM has achieved the EAL 4+ level of certification
Details – Mainframe Cost Reduction with Specialty Engines on IBM System Z • Cost savings are significant based on the Linux Specialty Engine: • IFL processors for Linux are additional engines dedicated to Linux workloads: • Support z/VM and Linux on System z • IFL processors run at “full speed” • • z9 EC, z9 BC, z10 EC, z10 BC, z9 EC, z9 BC, z800, z890 • Traditional IBM and Independent Software Vendor (ISV) mainframe software charges are unaffected. • Linux and z/VM charged only against the IFLs.
Reasons the data center is starting to migrate to Linux on System z • Floor Space • Use existing System z Hardware • No need to stand up new Hardware or Server (s) for a new project • Security • Ease of network attachment (Virtual IP Addresses) • Ease of Oracle Home Cloning/Same OS • Ease of standardizing Linux Releases • CLOUD Computing - Customers of my customer’s data center pay for what they use • SUSE 10 - Solid operating system under VM • RED HAT Available on Linux on System z
Reasons the Data Center is starting to migrate to Linux on System z • Ease of consolidation of potentially thousands of servers • Small < 100 user database system was first • Next was up to 5 million a day user system moved • UNIX TECH REFRESH being moved to Linux on System z • IBM AIX • HP UX • SUN/Oracle Solaris • Windows where applicable • Application Servers • Web Server • Charged by CPU usage keeps you honest • CPU reduction project – Close to complete
Details on Reason 10 Lowest total cost of ownership, total cost per user, and total cost per transaction Example – Cost Savings with IBM System z
Large Bank Saves $1.5M with System z 72% reduction in SW maintenance costs 95% reduction in connectivity costs 75% reduction in power/cooling costs 60% reduction in System Admin costs Note: Upgrade required for mainframe; Dell and HP were existing HW Prices are in USD. Prices may vary in other countries. details on next slide
(Details for Previous Chart) • Summary of Benefits: • 111-to-4 core reduction, 45:1 footprint reduction • Up to 72% software maintenance cost reduction • Improved application reliability, and efficient Disaster Recovery capabilities Prices are in USD. Prices may vary in other countries.
System z futures for a workload-optimized world Re-write the rulebook and set new standards for business-centric IT with IBM System z, to be the world’s premier workload-optimized platform for enterprise applications. Vision: Deliver the best of all worlds, Mainframe, UNIX, x86 and single function processors, integrated in a single system for ultimate flexibility and simplicity to optimize service, risk and cost across multiple heterogeneous workloads.
