SAP HANA using SAP block API
Controlled by the SAP HANA nameserver
Ensures exclusive access to persistence
Uses SCSI-3 PGR (Persistent Group Reservations)
Ensures that only the owning node has access to the persistence layer
Ensures that only the owning node has persistence mounted

SAP HANA: Persistence Layer
• Savepoints (data filesystem)
– In-memory data written to disk in regular intervals (5 mins default)
• Log filesystem
– Capturing all DB transactions since last savepoint
– Restore DB from last savepoint onwards
– High IOPS requirement but SAS drives sufficient
• SAP HANA scale-out (multi-node)
– Filesystems reside on external storage
– Enables node failover
– Foundation for DR and backup

Why Data Domain for SAP HANA?
High-speed, scalable systems – Throughput of up to 31 TB per hour – Reduce storage with inline deduplication
Reliable recovery – Data invulnerability architecture
Network-efficient replication – Send only deduplicated data across the network
Seamless integration – Qualified With all SAP HANA configurations – Optionally use EMC NetWorker for centralized
management – Can be upgraded to DD boost in future

EMC roadmap for SAP HANA backups
• Bill Reid from EMC IT describes:
• the SAP HANA deployment model,
• how SAP HANA relates to the rest of EMC’s enterprise applications, and
• what the SAP HANA roadmap currently consists of
EMC’s deployment model for SAP HANA
• SAP HANA use case and business value for end-of-quarter processing
Business use case
• What is EMC considering now after some experience with SAP HANA that was not planned initially?
• What would EMC IT do differently?
Lesson’s learned
