  3. 3. IntroductionAn Enterprise Resource Planning (ERP) system is the core business application for every company,covering a multitude of different business functions. This applies to both landscapes for large enterprisecompanies as well as for midsize companies with constrained IT resources.For midsize companies in particular, finding a platform that offers good performance, reliability andmaintainability while still offering the right price performance ratio can be a challenge.To specifically address midsize business enterprise resource planning needs, IBM® offers a robust andaffordable platform alternative based on Linux® and IBM POWER7® technology. IBM’s new IBMPowerLinux™ hardware line perfectly fits the needs of a small and integrated ERP setup.Linux, the industry’s fastest growing server operating system, offers a flexible, easy to maintain and cost-optimized environment that is readily used by midsize companies. Coupled with IBM’s new Linux-optimizedhardware, Linux and IBM PowerLinux servers provide an excellent price performance ratio compared totraditional Linux servers.SAP has supported IBM Power systems running Linux since 2004. IBM Power has proven its reliability andperformance leadership with SAP workloads repeatedly since then. Deploying SAP applications on the newIBM PowerLinux hardware offers midsize customers the advantages of an SAP ERP system with theopenness of Linux on an enterprise proven hardware platform. TMThe IBM PowerLinux Solution Edition for SAP Applications enables midsize customers to run multiple SAPlandscapes and their database on a single server, thus reducing floor space and other IT costs. The solutionoffers a robust virtualization solution by leveraging IBM’s advanced virtualization capabilities in PowerVM®technology. IBM has released a new PowerVM edition, PowerVM for IBM PowerLinux that is offeredexclusively for IBM PowerLinux servers. The IBM PowerLinux edition provides enterprise level functionalitywith a new pricing structure, comparable to x86 virtualization solutions.The net result is a highly robust, secure and pre-integrated solution that enables midsize businesses todeliver SAP applications faster, with higher quality and more affordably.Scope of This PaperThis paper describes a set up and configuration example for an SAP ERP landscape on a single IBMPowerLinux server. Its primary focus is on the hardware set up requirements and configuration.The scope is to provide a blueprint for a small, easy to maintain ERP landscape and to give an overview ofthe implementation process from bare metal set up to configuring the SAP system landscape.The architecture in this paper consists of an IBM PowerLinux server with PowerVM virtualization andmanagement tools, and the additional use of a storage extension using Storage Area Network (SAN)storage. On top of this virtualized environment, Linux and SAP products, SAP Solution Manager and SAPERP with an IBM DB2® database are installed and configured.Solution Elements of the IBM PowerLinux Solution Edition for SAP ApplicationsThe IBM PowerLinux Solution Edition for SAP Applications is a comprehensive solution comprised of IBMPower Systems hardware, IBM PowerVM virtualization, the Linux operating system, SAP Solution Managerand SAP ERP with IBM DB2. The following section describes the required elements of the solution.POWER SystemsFor the past 10 years, through sustained investment in the Power Systems platform, IBM has gone head-to-head with competitors in the UNIX market segment, and has become the leader of the UNIX market 3
  4. 4. 1segment . Power systems have supported Linux since 2002, and have developed strategic partnerships withRed Hat and SUSE to optimize, distribute, and support their Linux enterprise server releases on Powersystems.SAP software has been available on PowerLinux serverssince 2004, being the first virtualized Linux platform to runSAP workloads. Starting with Power4+ and up to thecurrent Power7 generation, PowerLinux has proven itsreliability and performance running SAP workloads overseveral years and hardware generations.SAP solutions on IBM PowerLinux servers offer businessesthe flexibility and economics of Linux on an enterpriseproven hardware platform.IBM PowerLinux 7R2 ServerThe SAP on PowerLinux solution edition is based on IBM PowerLinux 7R2 hardware. The IBM PowerLinux7R2 server is a 2U rack-mount server with two processor sockets. The processors are 64-bit POWER7 chipswith 8-core modules. There are two processor frequencies available:IBM PowerLinux 7R2 Rack Sever, Machine Type Model: 8246-L2C, or 8246-L2S for external drawersupportFeature Code Sockets Processor Frequency CoresEPL4 2 socket 3.3 GHz 16 coresEPL5 2 socket 3.55 GHz 16 coresThe PowerLinux 7R2 server provides a maximum of 16 DDR3 DIMM slots and is available with a maximumof 256GB RDIMM DDR3 memory.Both Linux distributions Red Hat Enterprise Linux and SUSE Linux Enterprise Server are supported, on the7R2. The supported distribution versions are RHEL 5 and 6 as well as SUSE Linux Enterprise Server 10 and11.Several configuration options with disks or tape drive are possible. The maximum internal storage withoutRAID is 6 x 600 GB. Additional external storage and a Fibre Channel Adapter to connect to it can be addedto the machine. Four PCI Express adapter slots can be equipped with required adapters.The IBM PowerLinux 7R2 system is a small up to medium size server that is the ideal platform for an SAPsolution for 250 with up to 1000 SAP users depending on the used memory from 64 GB to 256 GB and alsothe landscape setup. It combines the advantages of the Power platform with those of Linux as openoperating system, and offers an excellent price performance ratio. The whole SAP landscape can run on oneserver, nevertheless if the landscape is growing, scale out to additional servers is possible. 4
  5. 5. IBM Flex System p24LIBM PureFlex System is an expert integrated system that can support a hybrid environment of both POWERand x86 compute nodes to leverage the advantages of both hardware architectures within the sameenvironment. Different compute nodes can be installed and managed in one IBM Flex System chassis alongwith integrated Storage, Flex System Manager and Networking.IBM PureFlex systems can be built with your choice of two socket or four socket compute nodes: • Two and four socket Power Systems compute nodes for AIX, IBM i and Linux applications (Flex System p260 and p460) • Two socket PowerLinux compute node for Linux only applications (Flex System p24L) • Two socket x86 compute node for Windows or Linux applications (Flex System x240)The IBM Flex System V7000 Storage Enclosure is available inside or outside of the chassis. The FlexSystem Manager is an integrated management appliance that manages all of the physical and virtualresources within the Flex System chassis.IBM Flex System p24L compute nodes are Linux only, half-wide, two socket POWER servers with 64-bitPower7 processor cores in three speeds. IBM Flex System p24L compute nodes have a maximum of 16DDR3 DIMMs with up to 256GB memory.IBM Flex System p24L compute nodes, Machine Type Model: 1457-7FLFeature Code Sockets Processor Frequency CoresEPR7 2 socket 3.7 GHz 12 coresEPR8 2 socket 3.2 GHz 16 coresEPR9 2 socket 3.5 GHz 16 coresBoth Linux distributions Red Hat Enterprise Linux and SUSE Linux Enterprise Server are supported, on theIBM PowerLinux compute nodes. The supported distribution versions are RHEL 5 and 6 as well as SUSELinux Enterprise Server 11.Companies that already use the IBM Flex System can expand its use by adding an IBM Flex System p24LCompute Node to run their ERP landscape in the IBM Flex system.In this paper the set up and configuration example refers to either an IBM PowerLinux 7R2 rack server or anIBM Flex System p24L Compute Node.IBM PowerVMPowerVM, the virtualization technology of Power, is an intrinsic part of the IBM Power platform. It comprisesseveral virtualization features that improve management, utilization and administration of the Powerlandscape and therefore significantly reduces the total cost of ownership. 5
  6. 6. PowerVM is also a proven technology with Linux, and has demonstrated itsvirtualized efficiency for years, long before other Linux virtualization technologiesappeared. In SAP environments, PowerLinux was the first virtualized Linuxplatform, exploiting advanced virtualization features from the onset.The PowerLinux 7R2 server comes with the PowerVM for IBM PowerLinuxedition. It offers customers a comprehensive set of advanced PowerVMvirtualization features, e.g. Multiple Shared Processor Pools; virtualized disk andoptical devices (VIOS); Integrated Virtualization Manager (IVM); SharedDedicated Capacity; Live Partition Mobility (LPM) and Active Memory Sharing(AMS).Particularly important for SAP environments are the following virtualizationfeatures:A vital application for the management and monitoring of Power hardware is the Integrated VirtualizationManager. It offers functionalities like creating or deleting logical partitions, adding or removing resources, andthe ability to log on to the partitions via console. The Integrated Virtualization Manager is located on theVirtual I/O Server (VIOS), which provides virtual I/O resources to the logical partitions. A logical partition, orLPAR, is the equivalent term for a Virtual Machine (VM) used with x86-based virtualization. Only the VIOSowns dedicated physical I/O adapters while client partitions use virtual e.g. Ethernet or storage adapters.Using a virtual I/O server increases flexibility and leads to resource reductions, and therefore cost savings.A major virtualization feature of PowerVM is micropartitioning which enables up to 10 partitions perprocessor sharing CPU cycles. This enables the 16 core 7R2 server or compute node to host as many as160 Logical Partitions (LPARs). Dedicated CPU resources are never completely used, and free cycles arelost. By sharing the processor capacity across several partitions enables greater workload consolidation andbetter hardware utilization.A slightly different approach is to reserve CPU for a partition but donate free cycles to the shared CPU poolwhich can then be used by other LPARS. In this manner the partition with dedicated resources can use all itsdedicated resources without interrupts from other partitions. It all the dedicated resource is not requiredhowever, it can be shared with other LPARs. This configuration is called “shared dedicated capacity”.For partitions using shared processor resources there is a priority assignment option to make sure a specificLPAR gets enough resources. According to the priority of the partition it will be assigned the appropriateamount of CPU cycles. This ensures a better balance of resources while still ensuring high priority partitionsreceive the required resources. The resource distribution for the sharing partitions is done by the Hypervisor.In the case of the SAP architecture solution, the SAP production system should be assigned a higher prioritythan SAP development system.PowerVM Live Partition Mobility (LPM) allows relocation of LPARS between two Power servers withoutdowntime. Running SAP systems on an LPAR do not have to be stopped as LPM supports the concurrentuse SAP applications while the LPAR is being relocated. This means that the server does not have tobrought down for system maintenance or other types of planned SW and HW outages. This feature has beensupported for multiple Power processor generations and is one of Power’s key availability and cost reductionfeatures. The ability to run workloads without interruption provides continued service for businesses.For more information on PowerVM and SAP refer to the following resources: • IBM Datasheet for the Virtual I/O Server http://www14.software.ibm.com/webapp/set2/sas/f/vios/documentation/datasheet.html • IBM Whitepaper “Live Migration of Power Partitions Running SAP Applications” http://www.ibm.com/support/techdocs/atsmastr.nsf/WebIndex/WP101471 • IBM Redbook "SAP Applications on IBM PowerVM" http://www.redbooks.ibm.com/abstracts/sg247564.html 6
  7. 7. Required SAP products for the SAP landscape setupSAP ERPSAP Enterprise Resource Planning (ERP) is the core product of SAP AG. It is one of the most popularEnterprise Resource Planning tools and reflects the major business processes of a company, such asFinancial Accounting, Controlling, Logistics, Sales and Distribution etc.SAP ERP is the successor of SAP R/2 and R/3 and is based on the SAP NetWeaver platform, whichprovides SAP ERP with a comprehensive technology stack.The ERP system is customized according to the needs of the customer and its business processes. Theapplication can be extended with custom source code or other custom functionalities can be added. Not allmodules of the systems must be configured and used; only the parts that will be customized.SAP Solution ManagerCombining several supporting funtionalities in one tool, the SAP Solution Manager is an essential part ofevery SAP landscape. SAP requires its installation before other products can be added to the landscape.Key application areas of the SAP Solution Manager are for example change management support, solutionmonitoring, implementation and upgrades of SAP products, service-level management and reporting.It functions as SAPs entry point to the local landscape with early watch landscape monitoring, updatenotifications and support portal.Getting StartedIBM PowerLinux 7R2 Set UpThe example configuration described in this paper is comprised of four workloads or LPARs. One of theLPARs will host the Virtual I/O Server (VIOS) with the Integrated Virtualization Manager (IVM) and the otherthree LPARs will host the SAP installations that form together the SAP landscape.LPAR1The first LPAR is reserved for the VIOS with the integrated IVM. It does not need a lot of resources butshould be given the highest priority for resource sharing. Without the VIOS running, the attached LPARs willbe out of control as their virtual adapters will not be configured. Therefore it is important to set up the VIOSconfiguration in order for the other paritions to run properly. In this configuration the VIOS shares ethernetand storage adapters with the attached LPARs. Every LPAR owns a virtual ethernet and storage adapter.LPAR2The second LPAR hosts the installation of the SAP Solution Manager which is a pre-requisite for all the otherSAP product installations in the landscape and needs to be installed first. The SAP Solution Manager isbased on a SAP dual stack and should therefore be equipped with sufficient memory resources, although itwill not host of a lot of users and therefore does not need a high priority in cpu shares.LPAR3The SAP ERP development system is located on the third LPAR. SinceI it is a development system andused only for development and test purposes, the required resources are moderate, but need to fulfill aminumum for the ERP system to work. The priority of the resources could be lower compared to those of theproduction ERP system, which is located on the fourth LPAR on the PowerLinux 7R2 machine.LPAR4The production SAP ERP system is the core component of the SAP landscape and will have the highest userfrequency. Therefore, it should get the most CPU and memory resources, and with higher CPU sharing 7
  8. 8. priority. If the partition should not in general share resources with the other LPARS, another possibility wouldbe to set it up with shared dedicated capacity. It then only shares unused resources if they are not required.The LPAR for the production system is the partition with the most assigned system resources and also hasthe highest resource priority after the partition running the VIOS. This ensures ongoing availability of theproduction system.The following values are a sample configuration with 64 GB of memory. Please note that a separate sizingmust be done for every landscape, that this sample configuration should not be used as blueprint.Sample Memory Allocation by LPARLPAR1: VIOS 6 GBLPAR2: SAP Solution Manager 14 GBLPAR3: SAP ERP Development 10 GBLPAR4: SAP ERP Production System 30 GBSample CPU Allocation by LPARFor this small installation the LPARs can be part of one cpu pool and share their resources. A sampleresource entitlement could be:LPAR1: VIOS 0.2 (priority 255)LPAR2: SAP Solution Manager 0.4. (priority 64)LPAR3: SAP ERP Development 0.4. (priority 64)LPAR4: SAP ERP Production System 2 (priority 128)Additionally every LPAR gets two virtual adapters from the VIOS: 8
  9. 9. • ethernet adapter • storage adapterDisk space must be defined according to the required data in the system. A minimum requirement to installan SAP ERP system is at about 300 GB, but this does not provide sufficient storage for a lot of businessdata.LPAR resource assignment for memory, CPU and adapters is done via the IVM where new LPARs areadded. The IVM view shows the four LPARs with their memory and processors. In this case the LPARs areall in CPU sharing mode and are part of one CPU pool. The IVM can also be used to monitor the LPARsrunning during production.For more detailed information on IVM with IBM PowerLinux 7R2 servers, consult the Architecture and SizingGuide for IBM PowerLinux and the Implementation and Tuning Guide for IBM PowerLinux in the PowerLinuxCommunity on DeveloperWorks. • PowerLinux Communityhttps://www.ibm.com/developerworks/mydeveloperworks/groups/service/html/communityview?communityUuid=fe313521-2e95-46f2-817d-44a4f27eba32Configuration Requirements for your hardwareThe amount of the CPU and memory resources, as well as disk space described above is only an examplefor the architecture. Every SAP landscape has different requirements, thus the sizing for the landscape willvary significantly based on factors like the number SAP users, peak workload requirements, etc.An important pre-requisite for any server’s successful deployment is planning its workload capacity, physicaland virtual resource, and implementation steps. Take time to size the SAP landscape planned for the server.Sizing should also take into consideration if attached hardware will be needed to provide sufficient storage.Proper sizing will prevent running out of capacity, or conversely,wasting resources that will not be used. Besure to consult resource guidelines in SAP documentation based on performance results from SAPbenchmarks. The following site can provide useful information: • IBM Sizing and Planning Questionnaire for SAP Solutions http://www.ibm.com/support/techdocs/atsmastr.nsf/PubAllNum/PRS261 9
  10. 10. You should also contact your IBM representative or SAP business partner to help plan and size SAPlandscapes on Power Systems. IBM can provide assistance with the planning and deployment of yourPowerLinux server, setting up your SAP landscape, and migrating data. For IBM Lab Services Assistancefind contact information at: http://www.ibm.com/systems/services/labservices/PerformanceSAP Sales and Distribution (SD) Benchmarks prove the performance of Power Systems in combination withSAP workloads. SAP SD Benchmarks are a common vehicle to show the performance of a platform. Theperformance of a benchmark run is measured in the unit called SAPS that indicate the capacity of a server.The performance measurements are then the basis for capacity sizings of production SAP systems and theirhardware planning.IBM PowerLinux benchmark runs with both 12 and 16 core hardware demonstrated market leadingperformance of Linux running on Power hardware.For more information and current benchmark runs please visit the SAP SD Benchmark site. • SAP SD Benchmark information http://www.sap.com/solutions/benchmark/sd2tier.epxSAP landscape setupThe described SAP landscape is a very basic setup to cover the major business processes of a companywith a SAP ERP system. Additional products may be added to the described landscape.The setup of the SAP landscape starts with the Solution Manager. Its installation is a prerequisite to run SAPand it offers some support tools for the landscape setup. It is required for every SAP landscape regardless ofthe number of SAP installations attached.The major parts in the landscape are two ERP installations. One system is used as a development and testsystem, and the other one is used for production. Code changes or Service Pack installations are firstperformed on the development system and are also tested there. After successful testing, the changes aredeployed into the production environment. This process ensures that the production system remains a stableenvironment, and is unaffected by possible issues caused by beta/pre-production code. The ERP landscapecould even be enhanced to three systems, a development system, a separate test system and theproduction system. As this landscape requires setting up and maintaining three SAP systems, it is onlyrequired for large or extremely sensitive environments. For small and midsize installations, a two systemERP landscape is sufficient.Both the development and the production ERP system are configured as two-tier systems that have thedatabase and application logic on one server. This ensures an easy to maintain infrastructure that keepssetup and administration effort low. For bigger installations it is also possible to set up the database andapplication logic on separate LPARS or hardware.To learn more information about SAP landscape setup options and to read more about SAP systemconfigurations, please view the SAP on Power Linux reference architecture paper. It describes thePowerLinux architecture for use with an SAP landscape. • SAP on PowerLinux reference architecture http://www.sdn.sap.com/irj/scn/go/portal/prtroot/docs/library/uuid/904b62ee-a64d-2f10-9cae- 93f1fe232b03?QuickLink=index&overridelayout=true&53953379192934DB2® UDBTo leverage database optimization with SAP and POWER7, it is recommended to use the IBM DB2database management system with the IBM PowerLinux Solution Edition for SAP Applications. IBM offers a 10
  11. 11. DB2 LUW version that was developed jointly with SAP and is optimized for SAP applications and the SAPNetWeaver platform running on Linux.DB2 is performance-optimized for SAP workloads, and offers a simplified storage layout and automaticstatistics collection. With the DBCockpit, DB2 offers multiple enhanced monitoring features that are unique tothe SAP system. Recent SAP SD Benchmarks with a PowerLinux environment and DB2 demonstrate theoptimal combination of operating system, hardware and database.The DB2 database setup is embedded in the SAP install routine for SAP products, offering a quick and easyinstallation of the database. The database is shipped and fully integrated in SAP applications as one product.This sample architecture uses a DB2 v9.7 database for SAP installations. Other versions of DB2, however,are also supported.For more information on SAP and DB2 please visit • DB2 and SAP information by IBM http://www.ibm.com/solutions/sap/db2 • Features in DB2 v9.7 for SAP http://scn.sap.com/docs/DOC-8062Migrating to DB2IBM offers standardized procedures to help you migrate your database to DB2 if you are already a SAPcustomer and want to leverage the advantages of DB2. Migrating to DB2 is simple and ensures younumerous benefits such as easy database compression and excellent performance.The change to new hardware is also a perfect time to switch your database, so if you are planning to move tonew PowerLinux hardware consider migrating to DB2 LUW.For more information on database migration to DB2 please visit • Redbook “DB2 Optimization Techniques for SAP Database Migration And Unicode Conversion” http://www.redbooks.ibm.com/abstracts/sg247774.htmlor contact your IBM representative.IBM Systems StorageThe example configuration in this paper uses internal hard drive disks. External storage is also an option,and often preferred since ERP is a mission critical workload for midsize and large enterprise companies. Useof external disks will increase data security and reliability. It is also likely that over time growing businessneeds, and hence storage requirements, will eventually exceed the maximum internal disk storage of an IBMPowerLinux server. Thus the recommendation for this SAP setup is to add external storage to the landscapein order to provide extra capacity for landscape growth in the future. This storage could also be used forother applications that may run in the PowerLinux landscape.External storage can be added as Disk Storage, Network Attached Storage (NAS) or storage in a StorageArea Network (SAN). The advantage of external storage is that it can be easily extended and can offeradditional administration tools for its management.Using external storage also brings other advantages to the landscape, e.g. the flexibility to use live partitionmobility if replacing a Power server or adding more Power servers to the landscape. Live partition mobility allows you to move easily between PowerLinux servers while the data still stays on the same disk space. A small and very cost efficient storage box that perfectly fits with IBM PowerLinux hardware and the described sample 11
  12. 12. architecture is the IBM DS3500 express storage, which is available with up to 12 or 24 disks.It includes 6 Gbps SAS systems, a built-in storage management software, Fibre Channel access and datasecurity with full disk encryption.For further information on supported storage solutions that work in a virtualized Power environment with aVirtual I/O Server please visit • Datasheet for the Virtual I/O Server with storage solutions section http://www14.software.ibm.com/webapp/set2/sas/f/vios/documentation/datasheet.htmlConclusionThe SAP landscape described in this paper gives you a starting point to configure a compact SAP ERPlandscape on PowerLinux hardware. Depending on the requirements of your business your landscape mayvary from the example. Regardless, PowerLinux hardware and PowerVM technology provide an idealplatform for SAP solutions. All major SAP products are available on PowerLinux and each landscape can becreated according to your business needs. This applies for both new SAP setups as well as migrations toPowerLinux.PowerLinux offers you the flexibility to start small, and to grow your SAP landscape and other workloads thatyou might want to add to your PowerLinux hardware.For additional information on IBM PowerLinux servers with SAP workloads refer to the following URLs: • IBM PowerLinux http://www.ibm.com/power/powerlinux • SAP Community Network: SAP on IBM Power Linux http://scn.sap.com/docs/DOC-8438 12
