Network Configuration for SAP HANA System Replication (HSR) You can configure additional network interfaces and security groups to further isolate inter-node communication as well as SAP HSR network traffic. SAP HANA Network and Communication Security You set up system replication between identical SAP HANA systems. More and more customers are attaching importance to the topic security. Its purpose is to extend SAP HANA memory with a disk-centric columnar store (as opposed to the SAP HANA in-memory store). Extended tables behave like all other SAP HANA tables, but their data resides in the disk-based extended store. The latest release version of DT is SAP HANA 2.0 SP05. You can also encrypt the communication for HSR (HANA System replication). Log mode normal means that log segments are backed up. Dynamic tiering enhances SAP HANA with large volume, warm data management capability. The datavolumes_es and logvolumes_es paths are defined in the SYSTEMDB globlal.ini file at the system level but are applied at the database level. subfolder. 2685661 - Licensing Required for HANA System Replication. The new rules are Contact us. different logical networks by specifying multiple private IP addresses for your instances. 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. It would be difficult to share the single network for system replication. ########. The host and port information are that of the SAP HANA dynamic tiering host. Dynamic tiering adds smart, disk-based extended storage to your SAP HANA database. There can be only one dynamic tiering worker host for theesserver process. documentation. Have you identified all clients establishing a connection to your HANA databases? need not be available on the secondary system. At the time of the parameters change in Production both TIER2 and TIER3 systems were stopped and removed from Replication setup Prerequisites You comply all prerequisites for SAP HANA system replication. Below query returns the internal hostname which we will use for mapping rule. By default, on every installation the system gets a systempki (self-signed) until you import an own certificate. SAP HANA communicate over the internal network. In the following example, two network interfaces are attached to each SAP HANA node as well You may choose to manage your own preferences. This blog provides an overview of considerations and recommended configurations in order to manage internal communication channels among scale-out / system replications. Activated log backup is a prerequisite to get a common sync point for log
Figure 12: Further isolation with additional ENIs and security Dynamic tiering is targeted at SAP HANA database sizes of 512 GB and larger, where large data volumes begin to necessitate a data lifecycle management solution.
