Comingsoon

SAP HANA System Replication● SAP HANA replicates all data to a secondary SAP HANA system (standard SAP HANA

feature). ● Data is constantly pre-loaded on the secondary system to minimize recovery time objective

(RTO)● RHEL-HA support all HANA releases from HANA1.0 SPS08, Scale-Up● Limited support for Scale-Out environments

RHEL-HA

● Support of MCOD, MCD, MCOS● Additional resource groups and

constraints need to be configured● Support of Active/Active

(read enabled) in HANA 2.0

For more details: https://goo.gl/cqFPdb

SAP HANA System Replication Cost Optimized● Alternative for local high availability● Allows non-prod systems on secondary, resources are freed for non-prod instances

(no/less data preload of production database)● During take-over the non-prod operation needs to be ended● Take-Over performance similar to cold start-up of SAP HANA

RHEL-HA

● Setup similar to normal setup● Additional resource groups and

constraints need to be configured For more details: https://goo.gl/cqFPdb
