What is SAP HANA?
A runtime platform, an in-memory database, and a development platform
SAP’s strategic direction: Upcoming version of Business Suite includes HANA
– SAP Business Suite 4 SAP HANA (SAP S/4HANA)

SAP HANA High Availabilty
These things are different– High Availabilty– Desaster Recovery
Approaches for increasing HANA availabiliy– Storage Replication (dependant on storage vendor)– Scale-Out (Auto-Host Failover, built-in)– SAP HANA System Replication (built-in, but the
failover is not integrated)

DR– Cold start of database => long time to full
performance– Typically manual (or scripted) failover– Simple & robust
HA-Setup– Minimizes downtime– Automatic failover– Pacemaker cluster setup required (know how)– Failover testing required

Standardize to simplify your entire landscape.
• Standardize your operating system across all SAP deployments in your IT estate to reduce the complexity.
• Deploy the same OS in both existing and evolving IT estates, from development through production.
• Standardize the stack from operating system through application database.
• Standardization across all workloads (not just SAP) creates an agile infrastructure designed for scale.
• Standardization enables IT to ramp up more quickly on new technologies (e.g., SAP HANA).
