IBM SAP International Competence Center 1 Executive Overview Today IT leaders are facing a lot of new challenges, such as: - IT has become more and more the center of business - IT capabilities needs to deliver faster and with greater flexibility - Complexity of IT systems has grown significant - Cost especially for management and administration of IT systems are growing and are the key cost factor today SAP eco systems are especially affected by these challenges as they form the IT backbone of customers business. With PureSystems IBM delivers a new technology approach to face and answer the new challenges in entire IT eco systems. IBM PureSystems positions into the existing system portfolio and is not a replacement. It is a smarter computing approach. Systems with integrated expertise will dramatically speed the deployment of new IT and SAP processes as well as services and reduce many of the risks and inefficiencies that are inherent in today’s fixed, deterministic IT solutions. SAP business applications running on IBM PureSystems are: - Built-in Expertise: Capturing and automating what experts do – from the infrastructure to SAP applications - Integration by Design: Integrating POWER / x86 and storage hardware – in a single, ready-togo system - Simplified Experience: Making every part of the SAP and total IT lifecycle easier with integrated management of the entire system and a broad open ecosystem of optimized solutions Expert integrated systems promise a future with far less reliance upon costly system design skills that businesses neither desire, nor understand. Embedded business and technology patterns of expertise replace many system design tasks, changing the economics for SAP ecosystems. This paper covers the members of IBM PureSystems family of expert integrated systems. Each of the systems leverages the expertise and best practices from decades of client engagements and optimizations around the world to address ordinarily complex tasks with patterns of expertise. They are fully integrated by design and tuned by IBM labs and factories This document will provide an overview, on the latest IBM PureSystems platform and its technology usage for the SAP ecosystem consisting of the SAP NetWeaver technology layer, SAP Business Suite applications,SAP HANA and complementary SAP modules. Focus in this document is clearly on the Intel processor based units but will also provide information for integrated SAP scenarios with IBM POWER based units. More detailed information on the Power7 nodes are available in the Reference Architecture: “IBM PureFlex Solution for SAP Business Suite Reference architecture for IBM POWER and IBM AIX based core SAP systems on IBM PureFlex System featuring IBM Systems Solution for SAP Business Suite and SAP HANA - IBM entry cloud configuration for SAP solutions”. Links are included in the resource section. Latest developments extend the management capabilities of PureSystems beyond the units natively contained within the PureFlex chassis, towards external special purpose compute nodes, namely IBM Systems x servers running an SAP HANA in-memory database and applications as an solution described in this reference architecture. The IBM Flex System Manager serves as the unified management console for the components contained within the IBM PureFlex System chassis and the external IBM Systems Solution running SAP HANA. The Flex System Manager functions available and their fit into SAP landscape monitoring are documented in this paper as well. This reference architecture paper is aimed at informing the IBM Sales force and IBM Business Partners of IBM PureSystems Solutions for SAP, especially for technical sales and architects. This paper is a dynamic document, which means that it will grow as soon as more tests / PoC’s with IBM PureSystems and SAP applications have been performed.

  • 6. IBM SAP International Competence Center 2 Introduction 2.1 IBM PureSystems Platform Overview 2.1.1 Integrated Platform Concept The IBM PureSystems Platform is an integration platform for different server architectures (POWER and x86) and the associated operating systems. Integration also applies for systems storage from a physical and management perspective. The platform concept includes the following major components.  Flex System Enterprise Chassis is a rack-optimized, 10U modular design enclosure that holds up to 14 (1-bay) nodes. It features: - all new Intel processor based and Power compute nodes (in addition up to seven 2-bay compute node or three 4-bay compute nodes) - redundant power supplies / fans - Chassis Management Module (CMM) - support for up to four traditional fabrics using networking switches, storage switches, or pass-through devices - two IBM Flex System Managers (FSMs) for redundancy - IBM X-Architecture: The Flex System Enterprise Chassis is an IBM X-Architecture system that leverages proven innovative IBM technologies to build powerful, scalable, and reliable compute node platforms. It provides features such as IBM Predictive Failure Analysis (PFA) and real-time diagnostics.  Chassis Management Module (CMM) The CMM replaces the Advanced Management Module (AMM) known from legacy IBM BladeCenter. Both provide basic infrastructure access and single chassis management. CMM is used to communicate with the service processor in each compute node to provide system monitoring, event recording, and alerts, and to manage the chassis, its devices, and the compute Document: Author: Reference Architecture - SAP Systems on IBM PureSystems Michael Siegert, Paul Henter © Copyright 2013 IBM Corporation.

  • 7. IBM SAP International Competence Center nodes. The chassis supports up to two Chassis Management Modules. If one CMM fails, the second CMM can detect its inactivity and activate itself and take control of the system without any disruption.  Flex System Manager (FSM) The CMM can be complemented by a dedicated management node running the Flex System Manager (FSM) software stack while providing unified access and end-to-end management of up to four heterogeneously populated IBM PureSystems chassis. FSM functionality is comparable to IBM System Director. Some key FSM functions are: - Up to 4 Chassis Management - Setup & configuration wizards - Heterogeneous Nodes (IT Entities, ITEs) Server, Storage, Network Lifecycle Mgmt - Discovery, Inventory, Updates, Configuration, Status, Reliable Logging / Events - Active Energy Manager - Network Control with Voltaire Fabric Mgt (Discovery & Monitoring, Fabric Service Provisioning) - Single Sign-on, Audit Logging, Role based access control, User Management - Integration APIs to higher level systems and enterprise management sw, e.g. Systems Director, Tivoli Suite - Virtualization and workload management - IT organizations can consolidate workloads onto Flex Systems Manager platform to gain integrated, flexible IT for superior economics, managed using a single point of management. - Deployment of new or existing workload onto Linux, Windows, or competitive platforms - Upgrade of current rack or blade infrastructure to an integrated environment - Optimization of application performance such as SAP by migrating them to Flex System Manager - Move into advanced stages of virtualization or a private cloud deployment Up to two FSMs in each four-chassis configuration (one FSM in two of the four chassis) can be installed for redundancy. This enables the system to continue to operate without disruption if one fails.  Storage Node Besides the compute nodes, customers can integrate IBM Flex System V7000 storage with full SAN Volume Controller functionality into the same 10U-chassis . IBM Flex System V7000 storage system integrated into the PureFlex System is designed to be easy to use and enable rapid deployment. Flex SystemV7000 systems support extraordinary performance and flexibility through built-in solid state drive (SSD) optimization and thin provisioning technologies. With non-disruptive migration of data from existing storage, you also get simplified implementation, minimizing disruption to users. And advanced storage features like automated tiering, storage virtualization, and replication are designed to help you improve the efficiency of your storage. As part of your PureFlex System, Flex System V7000 can become part of your highly efficient, highly capable, next-generation information infrastructure. Highlights o o Document: Author: Integration by design: a single user interface to manage and virtualize internal and third-party storage that can improve storage utilization up to 30 percent Built-in expertise: built-in tiering and advanced replication functions are designed to improve performance and availability without constant administration Reference Architecture - SAP Systems on IBM PureSystems Michael Siegert, Paul Henter © Copyright 2013 IBM Corporation.

  • 8. IBM SAP International Competence Center o Simplified experience: single user interface simplifies storage administration to allow your experts to focus on innovation To meet today's complex and ever-changing business demands, you need a solid foundation of compute, storage, networking and software resources that is simple to deploy and can quickly and automatically adapt to changing conditions. You also need to be able to take advantage of broad expertise and proven best practices in systems management, applications, hardware maintenance and more. The IBM PureFlex System combines advanced IBM storage hardware and storage management software, along with patterns of expertise and integrate them in complete, optimized solutions. IBM Flex System V7000 storage system integrated into the PureFlex System consists of two controllers and one enclosure to hold 24 disks. The number of drives can be extended up to 240 drives per control enclosure, through Flex System V7000 expansion units. You can choose between SSD, SAS, and Near Line SAS drives. All storage and server within the PureFlex System are connected through the internal network; no additional, external cabling is required. o Features: o IBM System Storage Easy Tier Provides automatic migration of frequently accessed data elements to high performing SSDs o Thin provisioning Supports business applications that need to grow dynamically, while consuming only the space actually used o IBM Tivoli Storage FlashCopy Manager application-aware snapshots Performs near-instant application-aware snapshot backups, with minimal performance impact for SAP, DB2, Oracle, Microsoft SQL Server and Microsoft Exchange o IBM Real-time Compression Delivers extraordinary efficiency, enabling storage of up to five times as much active data in the same physical disk space o Storage virtualization and storage pooling Pools the storage capacity of multiple storage systems on a SAN, helping you to manage storage as a resource to meet business requirements and not just as a set of boxes. The storage pooling concept enables the deployment of storage beyond traditional “SAN islands”, and can increase utilization of storage assets.  System Connectivity – Networking - see chapter ‘System Connectivity’ below  Compute Node Power / Intel processor based - Power Based -> see ‘Power’ Reference Architecture ‘Efficiently Deploying SAP Landscapes on IBM PureSystems’ - Intel processor based -> see next chapter This concept matches the trend to multi - SAP system landscapes. Customers can exactly deploy the server units within the IBM PureSystems which they need to best accommodate their functional and non-functional SAP application requirements. While the core SAP Business Suite applications support almost all platforms and virtualization layers, certain SAP components like BWA, HANA, TREX are linked to Intel processor based CPUs and a Linux OS for example. IBM PureSystems and FSM allow for a unified monitoring and administration independent from the platform and OS mix while fully exploiting the native platform strengths of each IBM server family and the related environments.

  • 13. IBM SAP International Competence Center 3 SAP Reference Landscape on IBM PureSystems 3.1 Introduction to SAP Landscape Topology SAP customer landscapes consist of several SAP systems, each supporting a specific business application or dedicated to development and testing purposes. The most common SAP applications are combined as SAP Business Suite, which combines functions for ERP (Enterprise Resource Planning), CRM (Customer Relationship Management), SCM (Supply Chain Management) and BW (Business Warehouse). All of these modules – and much more - can be installed as dedicated SAP business applications, too. Their common underlying technology stack is the SAP NetWeaver layer. SAP NetWeaver provides typical middleware functionality to SAP sites such as Web Application Server, Portal, Service Bus, reporting etc, But the NetWeaver layer also provides abstraction of the SAP business Suite towards hw, OS and RDBMs. This enables the SAP BS to run on top of almost all server platforms. SAP Industry solutions and the “All-In-One” midmarket offering are based on the identical architecture and contain a blend of above BS modules customized with industry specific data and transactions. All of the Business Suite components can be either implemented in 2-tier or 3-tier mode. While 2-tier is the most efficient way of implementing a SAP instance from a resource, overhead and complexity perspective, 3-tier implementations provide advantages in scalability, availability and flexibility. Some backend applications can be extended with dedicated functional systems used to either complement, or to accelerate transactions. Prominent examples are Adobe Document Server, TREX, BWA, HANA. These systems do not rely on the NetWeaver stack and thus execute on dedicated x86based environments. For scalability reasons these modules often follow a scale-out paradigm. The variety and count of backend and complementary systems is customer individual, but in general demands for physical system consolidation by leveraging virtualization technologies. A further dimension of SAP landscape growth is SAP’s requirement of a strict isolation of Production an non-Production environments. Latter mostly comprises of Sandbox-. Development-, Test- and QAsystems. The SAP Transport System links these stages and allows critical changes in either OS or application being tested prior being promoted to business critical SAP instances.

  • 14. IBM SAP International Competence Center 3.2 Intel processor based nodes SAP Performance The latest SAP Certification Benchmark demonstrates clearly the advantages of the latest Intel processor® Xeon® processor E5 family. ITE Cores@GHz SAPS Certificate # IBM PureSystems x240 – 2 socket 16@2.9 43.520* 2012016 IBM PureSystems x440 – 4 socket 32@2.9 69,630 2012030 * The certification result is around 30% higher than the latest 2 socket Westmere EP SAP benchmark result. From that point of view the IBM PureSystems is an easy to migrate platform as it provides enough headroom to migrate existing SAP business applications from older Intel processor based infrastructure. There would not be a need of re-designing but the chance to consolidate and as such decreasing TCO of the entire SAP landscape. 3.3 SAP Positioning for Intel processor based nodes The following chart provides a positioning of the Intel processor based nodes inside the IBM System x / BladeCenter ecosystem. It can be clearly seen that IBM PureSystems is significantly extending the level of integration and manageability and this by reaching highest performance results. These are two typical criteria’s for positioning technology for SAP business applications. The chart below provides an overview of the IBM PureSystems compute nodes and their typical SAP application scenarios.

  • 15. IBM SAP International Competence Center The Intel processor based nodes (Romley EP) are the right choice for memory and performance demanding SAP Application Servers, Apps Server consolidation / virtualization, smaller SAP Database Servers or centralized systems. Especially for SAP Distributed Applications as well as SAP complementary applications the Intel processor based nodes are the platform of choice. 3.4 Supported SAP Solution Stacks For the Intel processor-based nodes the same software stacks as with tower / rack mount systems are supported, i.e. Microsoft Windows, Suse and Redhat Linux. Same is true for the common databases DB2 for Linux and Windows and Oracle for AIX. Restrictions on release level may apply, though. All supported OS/DB/SAP version release combinations are maintained in the Product Availability Matrix on the SAP Service Marketplace. Table 1 shows the supported OS and DB levels on Intel processor-based nodes at time of announcement: X = supported Oracle 11.2 WINDOWS SRV 2008 (R2)/X64 / 2012 SLES 10,11 RHEL 5 / 6 X(2008 only) X X DB2 LUW 10.1 X X X Microsoft SQL 2008 / 2012 X - - MaxDB 7.8 X X X X (2008 only) X (SLES 11 only) X(RHEL 6 only) Sybase ASE 15.7 Document: Author: Reference Architecture - SAP Systems on IBM PureSystems Michael Siegert, Paul Henter © Copyright 2013 IBM Corporation.

  • 16. IBM SAP International Competence Center On top of these OS/DB combinations, all SAP NetWeaver 7.x releases and modules are supported as technology and middleware stack. SAP NetWeaver® Landscape Virtualization Management is also supported for IBM PureSystems and extends the FSM with application monitoring and cloud enabling operations. 3.5 Landscape planning 3.5.1 System Layout Concepts Applications running on IBM PureSystems can take full advantage of the virtualization and partitioning capabilities offered by the operating systems running on IBM PureSystems. For POWER nodes the identical virtualization and partitioning capabilities are available for AIX, IBM i and Power Linux using PowerVM. For x86 nodes the VMware, KVM and Hyper-V virtualization hypervisors are available. This enables a very flexible landscape implementation on IBM PureSystems. The SAP concept of separating production from development and test systems is applied by choosing separate OS instances for those systems. Depending on the sizing requirements this can occupy a dedicated node, or - in most cases – be a LPAR or VM in a shared resource pool which is partitioned to contain multiple components of a SAP Business Suite landscape. In order to make best use of the physical resources and considering Intel processor based nodes , we recommend combining virtual machines for production with high priority (i.e. weighting factor) with nonproduction VM’s with lower priority on a dedicated node. This allows unexpected load peaks within a SAP production system to be covered by additional CPU resources out of these less critical VM’s. Also it is a good idea to collocate SAP instances with recurring load peaks within a single node. E.g., SAP systems serving users in different time-zones fall into this category. SAP applications are rather memory consuming with a large workload dependent variation. The available memory on a Intel processor based node will be sufficient for many SAP workloads, in particular for the very common SAP ERP component which are mostly ABAP based and such that do not make use of a JAVA stack. The memory configuration for an Intel processor based node is especially important since the Intel Nehalem CPU introduction. Wrong memory configuration can have significant performance impact of the hosted SAP environments especially when running virtualized. A detailed overview how to build a performing memory configuration on an Intel processor based server for SAP can be found in the ISICC Sizing GuideLines. There are also sizing recommendations available for planning SAP landscapes based on SAP supported virtualization technologies for x86 systems. For customers who need scalability beyond a single node, or prefer SAP 3-tier implementations, or scaleout DB-Servers, the IBM PureSystems chassis and its inherent network topology provides an ideal physical consolidation platform with a single point of control for infrastructure management. IBM PureSystems scalability continues in the way that multiple (up to 4) chassis can be clustered and still managed as a single IT entity. However, when it comes to application scalability across nodes classical parameters like networking latency need to be considered, too.

  • 17. IBM SAP International Competence Center 3.5.2 Integration of complementary SAP components Certain SAP components are not available on all SAP supported operating systems and databases. If such components are required to support customers’ business processes, they need to be installed on top of a supported OS, which is not necessarily the same location where the SAP core applications are stored. With IBM PureFlex System, supporting both x86 and POWER processorbased operating systems, those complementary components can be tightly integrated into the landscape. The required hardware resources can be hosted within one IBM PureFlex System chassis. Besides the compact server footprint in the datacenter, the internal network eliminates the need for network cables and switches to connect the systems. The IBM PureFlex System management provided by CMM and FSM reduces the complexity of managing possible heterogeneous environment. This allows the creation of a complete SAP landscape within a single box – running either in a complete homogenous environment or heterogeneous with some SAP Business Suite components running on POWER nodes. 3.5.2.1 The IBM Systems Solution for SAP Business Suite and SAP HANA SAP HANA is the strategic in-memory database by SAP AG to accelerate in particular business analytics, but also transactional business. In order to achieve magnitudes of acceleration, SAP HANA exploits specific design features of the Intel EX processor architecture with optimized low-level coding. Consequently, SAP HANA is exclusively supported on certified hardware using this processor type – for example IBM System x3950 X5. The IBM SAP HANA offering is a standardized portfolio of System x hardware and internal (SSD, SAS) storage for data persistency, plus software components, and surrounding services. Exclusively Linux, namely SLES 11, is supported as operating system. As of today, such an appliance cannot be deployed on any compute node within the PureFlex chassis. However, certified x3950 X5 based HANA appliances, also including storage and system software components, may be installed in the same PureFlex rack. Connection to both x86, and POWER based internal compute nodes running standard SAP applications or complementary SAP HANA instances is done via Ethernet through a TOR switch. A big advantage of re-using external technology is that well established and beneficial concepts can be 1:1 applied for PureFlex focused landscapes, too. As an excelling example, IBM GPFS (General Parallel File System) not only enables the IBM SAP HANA solution to grow beyond the capacity of a single system into a scale-out solution, but also adds high availability and disaster recovery features to the IBM HANA appliance. The scope of the Flex System Manager has now been extended to allow the integrated management of PureFlex internal components and IBM x3950 X5 based SAP HANA building blocks. It provides administrative functions like  Manual discovery / inventory  Release Management (FW and SW installation and update)  Power Control Document: Author: Reference Architecture - SAP Systems on IBM PureSystems Michael Siegert, Paul Henter © Copyright 2013 IBM Corporation.

The IBM PureFlex System portfolio offers the administrative integration of the HANA building blocks (T-shirt sizes) listed in the below tables. They meet the SAP defined HANA sizing grid and do not need to be purchased together with a PureFlex System. This allows the integration of existing HANA systems with a newly deployed PureFlex System at customer site.

  • 20. IBM SAP International Competence Center SAP technology and management components, as well as common operational functions, like the Tivoli Storage Manager for Backup/Restore of ERP and HANA may be deployed on PureFlex compute nodes and act on both environments. In case of IBM SAP HANA scale-out configurations the Integrated Management Module of x3950 X5 servers and the SAP HANA appliance related network interfaces (like SAP client access, HANA Studio, ERP, backup and restore, HW/SW-Admin) will be connected to the PureFlex Device Management and Client Data network via Ethernet through TOR switches. Such a scale-out configuration is deployed with separate racks. The SAP HANA Appliances with PureFlex network topology of such a landscape is shown in the below picture. Depended on the amount of external network connections, single node IBM SAP HANA appliances may be connected via available ports on integrated switches of the PureFlex chassis.

SAP BWA has not been this highly optimized for the Intel EX-CPU type. This fact allows deploying SAP BWA appliances on XEON-based FlexSystem nodes running a SUSE Linux Enterprise Server 11 SP2 operating system. The “IBM Flex System Solution for SAP NetWeaver Business Warehouse Accelerator” extends the established IBM BladeCenter offerings for SAP BWA with scalable FlexSystem configurations comprising of x240 compute nodes inside the Flex-chassis and externally attached IBM Storage Systems DS3500. This combination meets the SAP BWA appliance criteria while providing an excellent price/performance ratio. The FlexSystem building blocks for IBM SAP Business Warehouse Accelerator Appliances can be found in the below table. As with the SAP BWA appliances based on IBM BladeCenter, the IBM GPFS filesystem improves overall I/O performance, data scalability, and resiliency. The building blocks have been pre-tested and, optimized to deliver easy integration and quick implementation. Order and shipment processes of the pre-built systems are identical to those of the traditional IBM BWA platforms. Since SAP BWA is an encapsulated appliance, it cannot exploit all functionality provided by FSM for full topology management. Passive – in the sense of monitoring - functions like inventory, system health, hardware service and support are applicable. Dedicated BWA-FlexSystem chassis can be attached to PureFlex systems hosting a SAP BI solution and monitored from there. Performing active administrative functions which may have an impact on the BWA configuration are not allowed, however.

  • 22. IBM SAP International Competence Center 3.5.3 SAP supported virtualization technologies for Intel processor based nodes 3.5.3.1 VMware vSphere5 With vSphere5 there is only the ESXi edition of the hypervisor available. ESXi Server is the product name of a thin virtualization layer that runs directly on x86 hardware without any operating system being involved. ESXi Server provides the environment for multiple virtual machines to run on a single x86 server. Its main task is to create the illusion for each virtual machine that it runs on its own set of hardware and maps those virtual hardware interactions to the physical hardware. VMware vCenter is the key management component. It groups several ESXi servers together into a pool, called a cluster. vCenter provides a single management interface to all participating ESXi servers and represents a uniform view of its resources. It is also instrumental in providing Virtual Infrastructure Services, such as VMotion and high availability (failover protection). VMware ESXi Hypervisor Facts: Host • 64-bit VMkernel • 2 TB host memory • 160 logical CPUs • 512 virtual machines per host Virtual Machines • 32-Way Virtual SMP (combination of sockets / cores) • 1011 GB RAM 3.5.3.2 Hyper-V Microsoft's Hyper-V R2 Hypervisor is available as a component of Microsoft Windows Server 2008 R2 as well as a stand-alone product named Microsoft Hyper-V Server 2008 R2. Hyper-V poses an interesting value proposition to Microsoft customers in that it is included with the cost of the Standard, Enterprise, and Datacenter offerings of Windows Server 2008 R2. As many companies are already familiar with or standardize on VMware's Infrastructure 3 or vSphere offerings, to complete their own virtualization offering, Microsoft leverages their System Center technologies to enhance the management and functionality of their Hyper-V platforms. Since its initial release in 2008, Hyper-V has been both a stable and solid performing hypervisor. The two biggest concerns with Hyper-V have been addressed in the R2 release: It fully supports failover clustering and it now includes live migration, the ability to move a virtual machine from one physical host to another without service interruption. The Hyper-V role lowers the entry barrier to virtualization by using existing Windows Server 2008 architecture that is familiar to system administrators. The Child Partition Guest Operating Systems are enlightened (Microsoft's term for Paravirtualized kernels). Microsoft Hyper-V is a Type 1 Hypervisor, and is therefore an excellent candidate for any of IBM's x86based hardware offerings. Hyper-V is capable of leveraging the entire physical address space of the Windows Server 2008 R2 kernel, which is presently 1TB with Enterprise or Datacenter Editions. Hyper-V facts: Guest Systems for SAP:  Windows Server 2003 x64 (VMs configured as 1-way only)  Windows Server 2008 x64 (VM configured as 1, 2 or 4-way SMP) Document: Author: Reference Architecture - SAP Systems on IBM PureSystems Michael Siegert, Paul Henter © Copyright 2013 IBM Corporation.

  • 23. IBM SAP International Competence Center  Memory 64 GB per guest Desktop Version of OSs are not relevant for SAP. 3.5.3.3 KVM Rather than executing a proprietary hypervisor on bare-metal, the KVM approach leverages open-source Linux (including SUSE & RHEL) as the base operating system and provides a kernel-integrated module (named KVM) that provides hardware virtualization. KVM is a virtualization technology built into Linux that lets the kernel itself act as a hypervisor. KVM executes VMs closer to Kernel in a KVM Guest Mode avoiding User Mode context switching like traditional non-kernel integrated Type 2 Hypervisor. KVM provides full hardware virtualization by using a modified version of the open source QEMU hardware emulator package. This implies that guest operating systems have no requirement for OS paravirtualization. Linux KVM uses VirtIO as a framework for the implementation of I/O para-virtualization which utilizes user mode VirtIO drivers inherent in Kernel/QEMU for enhanced performance. The ability to use the existing Linux code base as host OS, combined with the bare-metal performance characteristics achieved through guest mode has made Linux KVM an increasingly popular hypervisor alternative. KVM architecture leverages the power of Linux and was built on trusted, stable enterprise class platform. KVM features: • Support 160 cores / 2 TB RAM on host and 64 vCPU / 512 GB RAM on guests KVM is now available as a standard module in current Linux distributions including Red Hat Enterprise Linux and SUSE Enterprise Linux. Red Hat is the furthest along in enterprise deployment capabilities, offering full support in RHEL 5.4. KVM is also available in SUSE Linux Enterprise Server 11.

An additional node is dedicated for SAP SCM and hosts SAP Solution Manager. Complementary SAP applications like CRM frontend and Adobe Document Systems are implemented on th the 4 node – all running on virtual machines under MS Windows. Maximum total SAP capacity for one node would be 43.520 SAPS providing enough headroom for sharing a node with 6 virtual machines (ERP: Prod/TST/DEV; CRM: Prod/TST/DEV).

SAP supported HA solutions like Microsoft Failover Cluster increases resiliency of mission critical components of SAP landscapes. Critical SAP components are placed inside the cluster; SAP DB instance is active on the first cluster member and in standby on the second cluster member. The SCS is implemented vice versa. In case of failure each cluster member can take over the critical component and keep the entire application running. The application server tier represented by the Dialog instanced are located outside the cluster and made high available by using multiple instances on dedicated nodes. SAP 3-tier landscape using chassis internal high speed network with built-in HA features to bring HA functionality on chassis level as well. Critical IBM PureSystems components like FSM or CMM can be configured redundant. Very large SAP DB-Server can be mapped to a multi-node DB scenario like DB2 PureScale or Oracle RAC with advantages that no clustering would be required and multiple DB-nodes would be available for scalability and hot-standby. The Flex System V7000 consists of two raid controllers (node pairs) always, enabling high availability access to the storage system by default.
