1 Technology Roadmap Arne Arnold, SAP HANA Product Management September, 2014

2 High-Level Overview

3 Why care about SAP HANA virtualized Why SAP HANA virtualized offer customers reduced TCO and additional options for planning and managing their systems landscapes. It also impacts CAPEX positively and hence can help lower the barriers to entry for SMEs and startups. How A hypervisor specific validation process has been established to determine all necessary constraints and best practices to ensure supportability and minimum performance requirements for running SAP HANA in virtualized environments. The first hypervisor which went through validation and is supported in the context of SAP HANA is VMware vsphere, but others will follow over time.

6 Hypervisor Support Status & Outlook

7 Currently Supported Hypervisors Currently supported hypervisors for running SAP HANA virtualized (on either SLES or RHEL guest OS): VMware vsphere 5.1 and SAP HANA SPS 05 (or later releases) for non-production use cases VMware vsphere 5.5 and SAP HANA SPS 07 (or later releases) production and non-production use cases o In General Availability for single-vm scenarios (see SAP Note for details). o In Controlled Availability for multi-vm scenarios, (see later slide for process description) Hitachi LPAR 2.0 and SAP HANA SPS 07 (or later releases) production and non-production use cases o In Controlled Availability for single- and multi-vm scenarios, (see later slide for process description) The following general constraints and conditions do apply while running SAP HANA virtualized: o Limited to scale-up scenario only (scale-out / multi-node database installations are not supported). o CPU & memory overprovisioning must not be used. Each SAP HANA instance / virtual machine is sized according to the existing SAP HANA sizing guidelines and corresponding hypervisor vendor recommendations. o SAP HANA installation was either done following by an SAP HANA certified engineer on SAP HANA certified hardware and successfully verified with the SAP HANA hardware configuration check tool (SAP HANA Tailored Datacenter Integration option), or system had been delivered pre-configured as certified SAP HANA appliance, with hypervisor installed by SAP HANA hardware partner.

8 High Availability Options High Availability solution Hypervisor High Availability Hypervisor HA + In-Guest Cluster (node recovery) Scenario Description Standard VM HA solution (based on shared file system, no split brain) Cluster manager handles switch over to secondary site, while VM HA is used to restart/restore availability of primary host, so HA cluster is ready for next fault situation (just in opposite direction). In-Guest cluster only SAP HANA System Replication * + In-Guest Cluster Standard 3 rd party cluster manager, not utilizing VM capabilities. Data replication between primary and secondary site may be done by storage replication (or similar). Operating system failures Yes Yes Yes Yes Standard 3 rd party cluster manager, not utilizing VM capabilities. Data replication between primary and secondary site is done by SAP HANA system replication, however. Hardware failures Yes Yes Yes Yes Application failures No ** Yes Yes Yes IP Redirect / DNS update Not necessary Handled by In-Guest Cluster Manager RTO Medium (crash recovery of DB) Medium (crash recovery of DB) Handled by In-Guest Cluster Manager Medium (crash recovery of DB) Handled by In-Guest Cluster Manager Shortest (IP redirect) RPO (synchronous) >0 (asynchronous) Remarks: Suitable also for disaster tolerant (DT) solution, in conjunction with site failover with VMware Site Recovery Manager and storage replication Note: 2 nd cluster node shall not reside on same physical host Possible cluster manager includes SUSE HA; HP Service Guard, SAP LVM, VMware Site Recovery manager Note: 2 nd cluster node shall not reside on same physical host Alternative to VM HA / DT solution, leveraging SAP HANA system replication to achieve possible lower RTO. * The SAP HANA host auto-failover is currently not supported, as scale-out supported is missing for virtualized environments ** In case of VMware, future plans to also support application failure detection 2014 SAP SE.

9 Technology Roadmap (from today to 2015+) Today Support for SAP HANA on VMware in non-production scenarios Support for single-vm SAP HANA on VMware in production and nonproduction scenarios Controlled Availability for VMware multi-vm scenarios, as well as Hitachi LPAR technology in production On Roadmap Support for scale-up on vsphere 6 Support for scale out scenarios Single VM production support Complement deployment options Extend platform support Add variety Multi VM support Support of additional hypervisors HANA scale out 8 socket hardware Future vsphere optimization / releases On single host On vsphere cluster H1/2014 H2/ This is the current state of planning and may be changed by SAP at any time SAP SE.

10 Application Process for Controlled Availability Customers interested in running multiple SAP HANA VMs on VMware vsphere 5.5 in production one or more SAP HANA VMs on Hitachi LPAR 2.0 in production can apply for Controlled Availability of SAP HANA production support by sending an to: This should contain High-level scenario description and timeline (e.g. planned Go-live date) Expected database size (compressed HANA DB size, number of users) Hardware spec (HW vendor, server t-shirt size), Planned HA/DR setup (if applicable), Contact details (if possible incl. SAP account number) for further communication All information provided will be kept confidential and is only being used during the selection process. Once accepted, customers will receive the usual SAP HANA support as also provided for non virtualized environments for the presented scenario SAP SE. All rights reserved. Customer 11
