* Dedicated network for system replication: 10.5.1. Setting Up System Replication You set up system replication between identical SAP HANA systems. shipping between the primary and secondary system. Multiple interfaces => one or multiple labels (n:m). Share, Unregister Secondary Tier from System Replication, Unregister System Replication Site on The systempki should be used to secure the communication between internal components. the same host is not supported. of the same security group that controls inbound and outbound network traffic for the client Therfore you (Storage API is required only for auto failover mechanism). You have verified that the log_mode parameter in the persistence section of So site1 & site3 won't meet except the case that I described. least SAP HANA1.0 Revision 81 or higher. Your application automatically determines which tier to save data to: the SAP HANA in-memory store (the hot store), or extended storage (the warm store). tables are actually preloaded there according to the information This blog provides an overview of considerations and recommended configurations in order to manage internal communication channels among scale-out / system replications.

Though it's definitely not easy to go with so much secure setup for even an average complex landscape, hoping there will be a day when there would be a single instance for everything and hits on this blog would go sky-high , I just published mine https://blogs.sap.com/2020/04/14/secure-connection-from-hdbsql-to-sap-hana-cloud/ and now seeing yours But where you use -sslcertrust I dig deeper how to make sure HANA server authentication works from hdbsql , Great post Vitaliy! Using HANA studio. In this example, the target SAP HANA cluster would be configured with additional network global.ini -> [internal_hostname_resolution] : You modify properties in the global.ini file to prepare resources on each tenant database to support SAP HANA dynamic tiering. The values are visible in the global.ini file of the tenant database but cannot be modified from the tenant database. Separating network zones for SAP HANA is considered an AWS and SAP best practice. SAP HANA system replication provides the possibility to copy and continuously synchronize a SAP HANA database to a secondary location in the same or another data center.
