6 What is Linux on System z? It is not your parents mainframe anymore!
7 What is Linux on System z? A native System z operating environmentPure Linux, an ASCII environmentExploits IBM System z hardware, including IEEE floating pointLinux for System z – 32 (31) -bit/64-bitNot a unique version of Linux or other operating systemDeveloped and supported by the Open Source CommunityDistributed by Novell SuSE, RedHat, and OthersNot 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 LPARHardware provides a pool of virtual capacityOnly fully supported Oracle environment in a VM aside from Oracle’s VM

9 What System z Hardware Brings to Linux: The most reliable hardware platform availableMTF measured in decadesRAS features built into hardwareScalabilityBoth Physical and LogicalNon-disruptive capacity upgrade on demandDesigned to support mixed work loadsComplete workload isolationHigh speed inter-server connectivityHigh Internal Bandwidth, sophisticated cache nestVirtualization
10 What System z Hardware Brings to Linux (cont’d): HipersocketsVirtual network between LPARs, at memory speedNetwork stays inside the box - secureIntegrated Facility for Linux (IFL) CPUFull Processing Speed, not clocked downIFLs upgrade as hardware is upgraded: z9>z10: 50% performance increaseProcessor-based software costs
11 Customer Trends From a perspective of the z Series SIG group Trend is to move to LinuxOracle strategic direction is LinuxOracle and IBM are supporting Oracle products on Linux on zLong list of 3’rd party vendor now support Linux on System zSteady yearly growth usage of Oracle on Linux on zSteady growth of Oracle solutions available on Linux on z
12 Top ten reasons for running Oracle on IBM System z The Mainframe has been the platform for mission criticalapplications for yearsReasons may vary why companies choose to run on the mainframeObjective of this session is to list some common reasonsYou can see if these fit your situation
13 Top ten reasons for running Oracle on IBM System z Excellent virtualization capabilities of IBM System z,highest resources use efficiency/utilization, mixed workloadsAbility to exploit existing disaster recovery plansLowest security breach risks/costs via most secure design, encryption, etcHigh availability features provided by IBM System zLowest power consumption, cooling, and data center floor spaceEase of interfacing with traditional dataIncreased performance and scalability capabilities of z10Specialty engines available on IBM System zEnd to end solution for dynamic infrastructure data centerLowest total cost of ownership, total cost per user, and total costper transaction
14 Details on using the VM Operating System The solid virtualization capabilities of z/VM and System z are a key reasonMature technologyVM/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
15 Details on Reason - VM (cont’d) Software Hypervisor integrated in hardwareSharing of CPU, memory, and I/O resourcesVirtual network – virtual switches and routersVirtual I/O (mini-disks, virtual cache, and so on)Virtual appliances (SNA/NCP, and so on)
16 Details on Reason - VM (cont’d) Easy managementFast 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.
17 Details – Consolidation Benefits Consolidate workloads – Green FeatureUse less power (electric)Distributed servers often run at average utilization levels in the range of 5% to20%.Run multiple images on fewer processorsAchieve utilization levels of 85 or 90 % or more
18 Details on Reason - Security Integrated cryptographic acceleratorAdvanced Encryption Standard (AES) 192 and 256Stronger hash algorithm with Secure Hash Algorithm (SHA- 512)Tamper-resistant Crypto Express2 featureSupports high levels of security for demanding applicationsFully programmable and configurableHighly scalable performance for SSL transactionsTrusted Key Entry (TKE) 5.2 with optional Smart Card reader
19 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
20 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 zIFL processors run at “full speed”• z9 EC, z9 BC, z10 EC, z10 BC, z9 EC, z9 BC, z800, z890Traditional IBM and Independent Software Vendor (ISV) mainframe software charges are unaffected.Linux and z/VM charged only against the IFLs.
21 Reasons the data center is starting to migrate to Linux on System z Floor SpaceUse existing System z HardwareNo need to stand up new Hardware or Server (s) for a new projectSecurityEase of network attachment (Virtual IP Addresses)Ease of Oracle Home Cloning/Same OSEase of standardizing Linux ReleasesCLOUD Computing - Customers of my customer’s data center pay for what they useSUSE 10 - Solid operating system under VMRED HAT Available on Linux on System z
22 Reasons the Data Center is starting to migrate to Linux on System z Ease of consolidation of potentially thousands of serversSmall < 100 user database system was firstNext was up to 5 million a day user system movedUNIX TECH REFRESH being moved to Linux on System zIBM AIXHP UXSUN/Oracle SolarisWindows where applicableApplication ServersWeb ServerCharged by CPU usage keeps you honestCPU reduction project – Close to complete

26 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.So, with future generations we will breakthrough some of the barriers that limit the way we use IT today. The objective is to move away from today’s Silo-ed approach to IT where each platform is managed as a separate and distinct entity, and instead focus on managing across heterogeneous platforms to give an end-to-end solution view. This will enable IT resources and services to be properly aligned according to business viewpoint, rather than limited to an IT viewpointThis new alignment will enable resources to be optimized to give the right level of service with appropriate risk at the right cost to the business.
