Use Case Deployment
• Use Cases Have Different Requirements – Scale Up – Scale Out – Master Node Consideration
• Requirements Determine Architecture/Deployment – Standalone/Scale up – Multinode/Scale out – High Availability Design – Disaster Recovery Approach – – –

HANA Standby node
Stretched HA (single node), up to metro distance
• Two data centers in metro distance (dependent on network latency and bandwidth)
• 1 + 1 + quorum, no non-prod system allowed on secondary site
• Quorum node ideally at third location, frequently installed at primary location
• Automatic failover with GPFS functionality, one GPFS cluster
• For BW on HANA and Suite on HANA

HA for single node configs in one DC SAP HANA system replication
• Low RTO, because the data is already active in memory in the secondary system
• Independent of the HW implementation
• Manual failover or additional cluster failover functionality
• Applicable for all use cases

DR Single node: with GPFS (synchronous)
• Two data centers in metro distance (dependent on network latency and bandwidth)
• 1 + 1 + quorum (one GPFS cluster) On the secondary site the HANA instance is not started, secondary site can be used for ONE different SAP HANA system (e.g. Non-prod) with storage expansion (EXP2524)
• Quorum node ideally at third location, frequently installed at primary location
• Manual failover
• For BW on HANA and Suite on HANA

DR Scale out: GPFS Replication (synchronous) aka. Storage Replication
• SAP Note 1755396 • Synchronous replication • Secondary site (identical setup active + standby) can be used for a
different SAP HANA system (e.g. Non-prod) with storage expansion • Not applicable for Suite on HANA

DR Scale out: SAP HANA Synchronous System Replication (available with SPS 6)
• Similar as before, but on the secondary site a non-prod system can run (duplicate persistence required)
• Higher RTO, because „Table pre-load“ is turned off
• Independent of the HW implementation
• Independent of the use case

GPFS and Disaster Recovery
© 2013 IBM Corporation © 2013 IBM Corporation
GPFS introduced concurrent file system access from multiple nodes.
Evolution of the global namespace: GPFS Active File Management (AFM)
Multi-cluster expands the global namespace by connecting multiple sites
AFM takes global namespace truly global by automatically managing asynchronous replication of data

• Can have multiple read-only caches

AFM Mode: Asynchronous Replication (GPFS TL-2)
• Asynchronous Replication in HA Pair – Cache site does the writing – Home site is failover
• Cache Fails – New cache can be defined
• Home Fails – New Home can be defined
