SUSE SAPHanaSR in 3 Facts
Reduces complexity- provides a wizard for easy configuration with just SID, instance number and IP address- automates the sr-takeover and IP failover ("bind")
Reduces risk- includes always a consistent picture of the SAP HANA topology- provides a choice for automatic registrations and site takeover preference
Increases reliability- provides short takeover times in special for table preload scenarios- includes the monitoring of the system replication status to increase data consistency
