  3. High Availability in IT • High availability is critical in today’s IT world! • Most businesses depend on their critical applications! • “Always On” became mandatory for many companies! • Downtime impacts productivity, money and reputation!

  4. Costof Downtime Is SAP uptime important to your business? • IT downtime causes significant damage to businesses! Source: ServiceMax, from GE Digital, commissioned Vanson Bourne to conduct a global study into unplanned downtime, “After The Fall: Cost, Causes and Consequences of Unplanned Downtime. “The Study surveyed 450 IT & field services decision makers in the UK, US, France and Germany across the manufacturing, medical, oil and gas, energy & utilities, telecoms, distribution, logistics and transportation sectors, among others.

  5. The Main Question is: Do you need always On availability for your SAP applications? Automatic Switchover is needed! if YES: if NO: Manual Switchover is a valid Solution!

  6. App Server Client General System Replication Setup virtual IP SAP HANA – secondary SAP HANA – primary (active) HANA HANA Do you need always On availability for your SAP applications? How about automatic Switchover? Linux Clustering needs to be configured! Always On availability achieved? SAP HANA System Replication (active) (data pre-loaded) Log Transfer by SAP HANA Database kernel Mgmt Mgmt VM VM VM vSphere Hypervisor vSphere Hypervisor Server Two datacentres and sync. data replication is required Storage If Yes: Log Data Data Redo Persistent Storage Persistent Storage

  7. App Server Client virtual IP SAP HANA – secondary SAP HANA – primary (active) HANA HANA SAP HANA System Replication (active) (data pre-loaded) Log Transfer by SAP HANA Database kernel Mgmt Mgmt VM VM Linux Cluster Services VM Let’s configure Linux clustering! Very complex to setup and maintain! vSphere Hypervisor vSphere Hypervisor Heartbeat Heartbeat Server Voting Device Storage Log Data Data “Pacemaker” 3rd Datacentre Redo Persistent Storage Persistent Storage

  8. App Server Client virtual IP SAP HANA – secondary SAP HANA – primary (active) HANA HANA SAP HANA System Replication (active) (data pre-loaded) Log Transfer by SAP HANA Database kernel Mgmt Mgmt Done! VM VM Linux Cluster Services VM Let’s configure Linux clustering! No Linux Clustering needed! Replace third Datacentre by Cloud Quorum vSphere Hypervisor vSphere Hypervisor Connect Agents Server Storage Log Data Data Redo Persistent Storage Persistent Storage

  9. App Server Client virtual IP SAP HANA – secondary SAP HANA – primary (active) HANA HANA SAP HANA System Replication (active) (data pre-loaded) Log Transfer by SAP HANA Database kernel Mgmt Mgmt VM VM VM Reduce complexity to gain uptime! vSphere Hypervisor vSphere Hypervisor Server Storage Log Data Data Redo Persistent Storage Persistent Storage

  10. App Server Client virtual IP SAP HANA – secondary SAP HANA – primary (active) HANA HANA Always On availability achieved! SAP HANA System Replication (active) (data pre-loaded) Log Transfer by SAP HANA Database kernel Mgmt Mgmt Takeover VM VM VM << Monitoring Monitoring >> vSphere Hypervisor vSphere Hypervisor Outage Server Storage Log Data Data Redo Persistent Storage Persistent Storage

  11. Simple ProLion Setup Complex Linux Cluster Setup • Disadvantages: • Complex cluster setup • High risk of failures (Cluster Services, Human Error) • Complextomaintain (Testing, Patch Mgmt, etc.) • Poor traceability • Advantages: • No more Linux clustering • Easy tosetup and configure • Simple Patch management • Easy to test and maintain • Lowest TCO (no 3rd datacentre) • Simple monitoring

  12. No SAP Solution Certification for Cluster Managers! Note: No solution certification is offered for cluster managers – Support is handled by solution partner directly Data source: http://service.sap.com/sap/support/notes/0002407186
