What is this solution about?
The new solution started by SUSE in the SAP LinuxLab is to automate the takeover in SAP HANA system replication setups.
The basic idea is that only synchronizing the data to the second SAP HANA instance is not enough, as this only solves the problem of having the data shipped to a second instance. To increase the availability you need a cluster solution, which controls the takeover of the second instance as well as providing the service address for the client access to the database.
