When you use SAP HANA to place hot data in SAP HANA in-memory tables, and warm data in extended tables, highest value data remains in memory, and cooler less-valuable data is saved to the extended store. In most case, tier 1 and tier 2 are in sync/syncmem for HA purepose, while tier 3 is used for DR. For your information, I copy sap note For more information about how to create a new There are two scripts: HANA_Configuration_MiniChecks* and HANA_Security_Certificates*. If you've got a moment, please tell us how we can make the documentation better. For more information about network interfaces, see the AWS documentation. SAP is using mostly one certificate for all components (host agent, DAA, SystemDB, Tenant) which belongs to the physical hostname (systempki). Internal Network Configurations in System Replication : There are also configurations you can consider changing for system replications. These are all pretty broad topic and for now we will focus on the x.509 certificates for encryption of the communication channels between server and clients. You comply all prerequisites for SAP HANA system
For the section [system_replication_hostname_resolution], you can add either all hosts or neighboring sites, but I am going to add only neighboring sites in order to remove all the configuration conflicts in below examples. isolation. Secondary : Register secondary system. Prerequisites You comply all prerequisites for SAP HANA system replication. This is the preferred method to secure the system as it's done automatically and the certificates are renewed when necessary. Download the relevant compatible Dynamic Tiering software from SAP Marketplace and extract it to a directory. subfolder. Switches system replication primary site to the calling site. the OS to properly recognize and name the Ethernet devices associated with the new On AS ABAP server this is controlled by is/local_addr parameter. There can be only one dynamic tiering worker host for theesserver process. Operators Detail, SAP Data Intelligence. I just realized that the properties 'jdbc_ssl*' have been renamed to "hana_ssl" in XSA >=1.0.82. It is also important to configure the appropriate network communication routing, because per default every traffic on a Linux server goes per default over the default gateway which is by default the first interface eth0 (we will need this know how later for the certificates). If this is not possible, because it is a mounted NFS share,
The instance number+1 must be free on both

Separating network zones for SAP HANA is considered an AWS and SAP best practice. SAP HANA system replication is used to address SAP HANA outage reduction due to planned maintenance, fault, and disasters. If you set jdbc_ssl to true will lead to encrypt all jdbc communications (e.g. Application Server, SAP HANA Extended Application Services (XS), and SAP HANA Studio, Internal zone to communicate with hosts in a distributed SAP HANA system as Persistence encryption of the SAP HANA system is not available when dynamic tiering is installed. SAP HANA dynamic tiering is a native big data solution for SAP HANA. With DLM, you can model data migration rules on SAP HANA tables, and move data at specified times between high performance SAP HANA memory and a lower cost storage and processing tier. Data Lifecycle Manager optimizes the memory footprint of data in SAP HANA tables by relocating data to Dynamic Tiering or HADOOP. Thanks a lot for sharing this , it's a excellent blog . Amazon EBS-optimized instances can also be used for further isolation for storage I/O. There are two types of network used in HANA environment: Since we have a distributed scenario here, configuration of internal network becomes mandatory for better system performance and security. To change the TLS version and the ciphers for the XSA you have to edit the xscontroller.ini.
