  1. Is your infrastructure Ready for SAP HANA? SAP HANA on POWER Benjamin Kwan (benkwan@nz1.ibm.com) Systems Specialist IBM New Zealand

  2. Evolution of SAP S/4HANA SAP ports its Business Suite applications to run on HANA • SAP introduces its own in-memory database. HANA will enable applications to run both transactional and analytical workloads on a single copy of the data • By this time, distributed Unix and Windows systems were available and SAP ported their ERP application to these platforms as R/3 • Multiple components were merged into SAP ERP such as BW, SEM and ITS. The business logic and technical layer were separated for ease of implementation • SAP started out with R/1 and R/2 as a real-time system offering on the mainframe. Initially it was a 1-tier system, which then became 2-tier with R/2 SAP introduces S/4HANA, an ERP replacement, that will form the Digital Core of SAP’s modernization of the enterprise business processes

  3. Rapid adoption of SAP HANA on POWER Systems Acceleration: 0 to >1500 clientsin 36 months 50+ CSP/MSP using IBM POWER for SAP HANA Clouds 4 out of the top 10 Fortune 500 Global 60% faster from procurement to go-live (e.g. 2.5 months instead of 6) 17 out of the top 135 European Companies • 2018 SAP Pinnacle awards Winner • IBM POWER Systems - Global Partner of Year – Infrastructure • Seidor - running on POWER, Cloud Partner of the Year

  4. What makes IBM Power Systems the best platform for clients’ mission critical SAP HANA deployments? Risk-free sizing and implementation • Dynamically adjust sizing to changing requirements • Grow number of systems and sizes on demand while project advances Reliable infrastructure for enterprise applications Best infrastructure to achieve scalability, response time and throughput requirements • Additional headroom for peak workload due to virtualization capabilities TCA: competitive to x86 TCO: better than x86 4 FlexibilitySuperior virtualization and management features to afford flexibility and maximum utilization ResiliencyUnsurpassed RAS (reliability, availability, serviceability) characteristics to support mission critical SAP applicationsPerformanceHighest throughput per core and core/memory bandwidth to deliver faster business results, up to 2x Intel-based alternatives Competitive Cost

  10. Enterprise Level Virtualization • Consolidate multiple HANA workloads onto fewer systems, increasing server utilization. • Live Partition Mobility (LPM) avoids service impact due to systems maintenance • HANA benefits from Enterprise Resource Pool (EP) and Cores on Demand (COD) by accessing capacity and resources in unexpected situations. • PowerVC improve administrator productivity and simplifies the management of HANA VMs and LPARs on POWER Systems servers.

  11. IBM Power Systems the Most Reliable Servers after IBM ZHow much Unplanned Downtime have you experienced, per server/per annum in minutes in 2017 – 2018? 2.1 minutes per year Source: ITIC 2017 – 2018 Global Server Hardware, Server OS Reliability Report

  12. Systems Architecturevs x86 • SMT enables higher throughput and reduces core count. Particularly suited to support HANA features such as the HANA indexing server, which is know to spawn many hundred threads. SMT technologies have been built to handle this type of behaviour • Large memory footprints enable larger single node HANA in-memory database systems and provide more flexibility to consolidate workloads • POWER systems feature superior CPU and Memory bandwidth to handle HANA in-memory data operations faster • Higher CPU clock speeds and overall processing capabilities leading to HANA record benchmarks 4x threads per core vs. Intel 24TB* larger memory space vs. Intel 1.8x system bandwidth vs. Intel 2x core performance vs. Intel * Scale-up for S/4 and SoH. For BW/4HANA or BWoH, the max is 16TB

  16. Better Total Cost of Ownership As business grows, the HANA database size increases, and larger server memory is required • In the SAP 2-socket server certification, POWER9 systems can support 33% larger HANA databases than x86 servers (4TB vs. 3TB) • AND • With less than half the cores • Which results in • Lower purchase and maintenance cost for smaller servers • Lower power consumption • Lower complexity Don’t get trapped by hardware restrictions

  17. IBM IT Economics Team TCO Comparison Cloud, x86 and PowerSwiss Customer case 2018 IT.Economics@us.ibm.com Assumed workload growth : year 1 => 25% , year 2 and 3 => 5% , year 4 and 5 => 0% • Main Assumptions • People cost Power & Cloud to x86 assumed to be 1,5 : 2 • Power discount typical for large client conditions • For x86 an end price of 30k per TB is assumed for servers > 512 GB • For Cloud (Azure) a premium network connection with unlimited data transfer is assumed and 50% discount on list price is assumed.

  32. 2686722 - SAP HANA virtualized on Nutanix Acropolis HypervisorVersion 2 from 18.09.2018 By issuing this SAP Note, SAP declares support for SAP HANA on Nutanix Akropolis, providing the following conditions are met: SAP HANA start release: SAP HANA 1.0 SPS 12 (122.19) Single and multiple SAP HANA production virtual machines on a single physical server CPU Architecture: Intel Skylake 2 & 4 socket (only supported processors) The minimum size of a virtual SAP HANA instance is a full socket (represented by at least 8 physical cores). The minimum is 128GB of RAM. The maximum size of a virtual SAP HANA instance is limited CPU-wise by the maximum size of a virtual machine on Nutanix AHV release, which is 168 vCPUs on 3 Sockets (3 Sockets only on 4 Socket Hardware), and 2,3TB of RAM. VM Size – full socket                  minimum 1 socket / maximum 3 sockets                  1- and 2-socket VMs on 2-socket (partly QPI meshed)                1-,2- and 3-socket VMs on 4-socket server (fully QPI meshed) Rules for virtualized SAP HANA on Nutanix AHV Each SAP HANA instance / virtual machine is sized according to the existing SAP HANA sizing guidelines and Nutanix recommendations. CPU and Memory over-commitment must not be used. The Time Stamp Counter (TSC) must be synchronized between all sockets/cores. Certified OS versions (from SUSE) and server combinations as listed on the SAP HANA hardware directory are supported when virtualized. SAP HANA Tailored Datacenter Integration (TDI) delivery methods are not supported for SAP HANA on Nutanix. The hardware must be listed on the SAP HANA hardware directory under “HCI certified hardware”. The SAP HANA installation must done by an SAP certified engineer, qualified as "SAP Certified Technology Specialist - Required exam: C_HANATEC_11 (*) - See SAP Training and Certification Shop for details [2] The SAP HANA Installation on SAP HANA HCI certified hardware must be successfully verified with the SAP HANA hardware configuration check tool [3]. Configuration and overall setup must comply with the latest version of the bestpractice guide [4]  and the here linked most recent best practice guide. This includes compliance to the SAP HANA core-to-memory ratio as reflected in the HANA Hardware Directory and virtualization calculus as described in the best practice guide as well as priority for SAP HANA production workloads over co-deployed non-production workloads. The ownership of the support is with the SAP HANA hardwarevendor providing the solution. In case of software issues SAP and Nutanix will jointly support virtual SAP HANA in production adhering to the SLAs defined in the customer support contract. If a reported problem is a known SAP HANA issue with a validated fix, SAP support will recommend the appropriate fix directly to the customer.  For all other performance related issues, the customer will be referred within SAP’s OSS system to the SAP HANA hardwarevendor for support. The SAP HANA hardwarevendor will take ownership and work with Nutanix and SAP and the customer to identify the root cause. SAP support may request that additional details be gathered by the customer or the SAP HANA HW partner to help with troubleshooting issues. In rare cases – SAP may require to re-produce the issue on SAP HANA running in a bare metal environment. SAP and Nutanix saw degradation compared in performance on bare metal in average of 4%, and this is to be expected in virtualized environments. Customers are encouraged to size correct and test performance before going live. The socket pinned to the Nutanix CVM must not be used for productive HANA workloads. Non productive and non -HANA are fine. Ist only a hardwarepartitioning
