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
