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

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

• http://www.vmware.com/files/pdf/customers/10Q3_MIAMI_DADE.pdf

• 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.

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

Business Continuity - Third Party In-Guest Clustering Solutions

Third party in-guest clustering solutions on top of VMware

• VMware KB 1034165 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

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)
