DR Solution for Standard Deployment

Table 1 shows the file systems used in standard SAP application deployment.

In standard deployment mode, all file systems are mounted on EVS disks. Therefore, SDRS is applicable to the SAP application systems. Figure 1 shows the DR solution for the standard deployment mode.

Solution Description

SAP applications are deployed in the standard mode, and SAP HANA is deployed in a single-node mode without HA required. AZ 1 is the production site, and AZ 2 is the DR site.

SDRS is configured for SAP applications, and asynchronous system replication is configured for SAP HANA. SAP applications are deployed on one PAS & ASCS node and as many AAS nodes as possible. SDRS is configured for each node. The system volume, data volume, log volume, and shared volume of SAP HANA are provided by EVS in AZ 1, and the backup volume is provided by SFS, and is mounted across AZs to both the production and DR sites. SAP HANA data is periodically backed up to the backup volume, or to an OBS bucket using CSBS or VBS.

If the production site is faulty, SAP applications are switched over to the DR site through SDRS. Servers and disks at the DR site become available immediately. SAP HANA restores to a specified data recovery point through backup files in the backup volume, or using CSBS or VBS.
