2 Agenda VMware HA and DR solutions SAP Performance Monitoring Why virtualization of business critical SAP applications?

3 Top Challenges for SAP Customers  Innovation – Build of optimized SAP infrastructures to support new business opportunities  Manageability – Delivery of better SLAs at lower Capex and Opex  Reliability – Highly reliable technologies and products  Agility – Flexible SAP Infrastructure as a Service for new and continously changing business requirement.  Cost Reduction – Provisioning of measurable and documented TCO and ROI metrics

4 Challenges of todays SAP landscapes Physical Infrastrukture limits SAP operation Different SAP Environments Multiple SAP Versions.Multiple SAP VersionsInfrastructureSilos

5 Lower CAPEX & OPEX Better “Quality of Service” Better IT Performance Higher Availability Why virtualization of business critical SAP?

6 Virtualization of all IT assets with one virtualization platform. VMware and SAP, a strategic partnership VMware vSphere, vCOps, SRM, vCHS

7 SAP is the Fastest Growing Workload on VMware % of Workload Instances That are Virtualized With VMware Source: VMware customer survey, Jan 2010, Jun 2011, Mar 2012, June 2013 Question: Total number of instances of that workload deployed in your organization and the percentage of those instances that are virtualized.

9 VMware Fault Tolerance, High Availability, DRS, VMotion Server Data Replication and Site Recovery Manager Location Protection against Hardware failure Planned maintenance with zero downtime Protection against unplanned downtime und disaster Storage VMotion Storage VMFS NIC Teaming, Multipathing Components Overview of VMware's Availability Options Data VMware Data Recovery and Data Protection solution from VMware or 3 rd Party provider

10 Business Continuity - Basic Concepts  VMware vMotion™ & Storage vMotion™ zero downtime maintenance live migration of SAP applications and data bases with transaction integrity  VMware Distributed Resource Scheduler (DRS) dynamic allocation of computer ressources to SAP workloads, e.g. to meet SLAs  High Availability (HA) monitors, starts and stops resources takes care of data consistency through fencing methods  Disaster Recovery (DR) replicates data to a recovery site "DR" is also often read as "Data Replication", but this is only a part of a Disaster Recovery concept provides failover and recovery methods (not necessarily automated)

11 Business Continuity - VMware HA Cost effective solution for multiple SAP systems independent of Guest OS SAP on VMware customers have achieved “three nines” availability Not application aware - no monitoring of SAP CI or database

12 VMware HA for SAP HANA Scale Out and High Availability  SAP HANA Physical High Availability Needs one Standby Server IDLE Server will be used only after fail over  Physical HANA HA is N+1 architekture 3+1 outage of one HANA node only! HANA Node 1 HANA Node 3 HANA Node 2 HANA Standby  SAP HANA vCloud Suite HA No standby or idle Server necessary In a Cloud architekture: migration of virtual machines in case of failure; ressource distribution as needed. Significant savings. VMware vCenter Operations VMware vSphere HANA Node 1 HANA Node 2 VMware vSphere HANA Node 3 Test & Dev VMware vSphere ASESAP Fully utilized Hardware, reduced cost

13 Business Continuity - VMware Fault Tolerance Single identical VMs running in lockstep on separate hosts, one is primary Zero downtime, zero data loss of ASCS virtual machine in case of hardware failure How much load can 1 x vCPU VM running ASCS handle: 200 concurrent users running SD txns, avg CPU utilization of ASCS VM < 5 %

14 Business Continuity – Application HA VMware integrated solution from different vendors Agents for DB and SAP installed in VM provide service monitoring and restart capability Integrated to vCenter via VMware HA API Application visibility from vSphere Client Bridges gap between VMware HA and in-guest clustering solutions es/techresources/10147

15 DIA DB CI MSCS / WSFC SLE 11 HAe Red Hat Cluster Veritas Cluster SteelEye LifeKeeper...others OS Business Continuity - Third Party In-Guest Clustering Solutions  Third party in-guest clustering solutions on top of VMware VMware KB shows how to share virtual disks, so every HA solution which does not use SCSI reservations is a potential candidate monitoring agents for database and SAP supports rolling upgrades for guest OS patching can also include data replication methods

16 VMware HA and DRS Cluster Example: Business Continuity - SLE 11 HAe App SCS App SCS DB App VMware DPM host offline SUSE Linux Enterprise High Availability Extension

17 VMware HA and DRS Cluster Example: Business Continuity - SLE 11 HAe App SCS App SCS DB App VMware DPM host offline SUSE Linux Enterprise High Availability Extension vMotion

18 Example: Business Continuity - SLE 11 HAe VMware HA and DRS Cluster App SCS DB App VMware DPM host offline SUSE Linux Enterprise High Availability Extension

19 Example: Business Continuity - SLE 11 HAe VMware HA and DRS Cluster App SCS DB App VMware DPM host offline SUSE Linux Enterprise High Availability Extension DB

20 Example: Business Continuity - SLE 11 HAe VMware HA and DRS Cluster App DB SCS App SUSE Linux Enterprise High Availability Extension failed, waiting for hardware maintenance VMware DPM powers up the host. Failed Virtual Machines get started by VMware HA.

21 Example: Business Continuity - SLE 11 HAe VMware HA and DRS Cluster App SUSE Linux Enterprise High Availability Extension failed, waiting for hardware maintenance App vMotion DB SCS

22 Example: Business Continuity - SLE 11 HAe VMware HA and DRS Cluster App SUSE Linux Enterprise High Availability Extension failed, waiting for hardware maintenance App DB SCS

23 START Determine Uptime requirements S/W monitoring required? H/W monitoring Yes rolling patch upgrades; replicated enqueue? Yes No VMware HA VMware HA + Application HA 3 rd Party Clustering in VMs (fastest failover) Cost / Complexity LOW MEDIUM HIGH H/W + S/W monitoring No Business Continuity - High Availability Solutions - Conclusion

24 Business Continuity - Site Recovery Manager Disaster Recovery Management Protect virtual machines by storage replication using integration adapters. Create and manage recovery plans directly from vCenter Server. Monitor availability of remote site and alert users of possible site failures. Store, view and export results of test and failover execution from vCenter Server. Non-Disruptive Testing Use storage snapshot capabilities to perform recovery tests without losing replicated data. Automated Failover Initiate recovery plan execution from vCenter Server with a single button.

25 VMware vCenter Operations Suite  Analysis: SAP Workloads Monitoring of performance peeks and under utilization Early handling of upcoming hardware failure  Prediction: Ressource Utilization Pattern for SAP Applications Pro active and prioritized ressource allocation for SAP Applications  Planning: SAP Application - Live Migrations Migration of SAP and other Applications with vMotion, Storage vMotion and Distributed Resource Scheduler (DRS) SAP HANAERP Sybase ASE SOLMAN vCenter Operations Suite: for SAP Applications
